While research has previously explored how phages sense environmental information to make this choice, most studies have focused on modelling known mechanisms that impact the decision. These mechanisms tell us what environmental information the phage does respond to, but not what it should respond to, as the signals sensed by the phage may serve as proxies for other sources of information. Here, using a mechanism-agnostic population dynamics model, we find that irreversible phage binding to lysogens protects sensitive host cells from infection. This results in lysogens being an additional environmental factor that the phage should sense while making its decision to undergo lysis or lysogeny. Using this model, we derive a responsive lysogeny probability for phages that respond to both cell and lysogen densities optimized towards invading phage-occupied systems, and show that it is more capable of invading and resisting invasion than phage with fixed lysogeny probabilities across different environmental conditions.","lang":"eng"}],"pmid":1,"OA_type":"hybrid","department":[{"_id":"CaGu"}],"corr_author":"1","year":"2026","scopus_import":"1","type":"journal_article","file_date_updated":"2026-06-16T12:45:09Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"1365-1373","publication_status":"published","publisher":"Oxford University Press","OA_place":"publisher","oa":1,"quality_controlled":"1","date_created":"2026-06-10T07:38:12Z","article_type":"original","title":"Responsive lysogeny under nonproductive phage binding","article_processing_charge":"Yes (via OA deal)","date_updated":"2026-06-16T12:46:02Z","month":"06","file":[{"relation":"main_file","checksum":"6d0f48566a7a36cb0c469e1968c9cb1c","file_name":"2026_Evolution_Wu.pdf","creator":"dernst","content_type":"application/pdf","access_level":"open_access","date_created":"2026-06-16T12:45:09Z","file_size":2077781,"success":1,"file_id":"22015","date_updated":"2026-06-16T12:45:09Z"}],"publication":"Evolution","date_published":"2026-06-01T00:00:00Z","author":[{"full_name":"Wu, Bryan","id":"3C521EBA-F248-11E8-B48F-1D18A9856A87","first_name":"Bryan","last_name":"Wu"},{"first_name":"Calin C","last_name":"Guet","orcid":"0000-0001-6220-2052","full_name":"Guet, Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87"}],"_id":"21985"},{"title":"Robust antibiotic sensitization of pathogenic Pseudomonas aeruginosa via negative hysteresis in the cell envelope","article_type":"original","date_created":"2026-05-31T22:02:12Z","month":"05","date_updated":"2026-06-02T07:14:35Z","article_processing_charge":"Yes (via OA deal)","author":[{"full_name":"Buchholz, Florian","last_name":"Buchholz","first_name":"Florian"},{"full_name":"Upterworth, Lina M.","first_name":"Lina M.","last_name":"Upterworth"},{"full_name":"Tueffers, Leif","first_name":"Leif","last_name":"Tueffers"},{"full_name":"Groth, Espen E.","first_name":"Espen E.","last_name":"Groth"},{"full_name":"Haas, Kira","last_name":"Haas","first_name":"Kira"},{"first_name":"Daniel","last_name":"Schütz","full_name":"Schütz, Daniel"},{"first_name":"Abigail","last_name":"Savietto Scholz","full_name":"Savietto Scholz, Abigail"},{"last_name":"Batra","first_name":"Aditi","full_name":"Batra, Aditi"},{"last_name":"Pal","first_name":"Surajit","full_name":"Pal, Surajit"},{"first_name":"Samarpita","last_name":"Banerjee","full_name":"Banerjee, Samarpita"},{"first_name":"Badri N.","last_name":"Dubey","full_name":"Dubey, Badri N."},{"full_name":"Franzenburg, Sören","last_name":"Franzenburg","first_name":"Sören"},{"full_name":"Kalsdorf, Barbara","last_name":"Kalsdorf","first_name":"Barbara"},{"last_name":"Rabe","first_name":"Klaus F.","full_name":"Rabe, Klaus F."},{"full_name":"Nurjadi, Dennis","last_name":"Nurjadi","first_name":"Dennis"},{"full_name":"Rupp, Jan","last_name":"Rupp","first_name":"Jan"},{"full_name":"Andersson, Dan I.","first_name":"Dan I.","last_name":"Andersson"},{"full_name":"Sondermann, Holger","last_name":"Sondermann","first_name":"Holger"},{"last_name":"Bramkamp","first_name":"Marc","full_name":"Bramkamp, Marc"},{"id":"68E56E44-62B0-11EA-B963-444F3DDC885E","full_name":"Römhild, Roderich","last_name":"Römhild","orcid":"0000-0001-9480-5261","first_name":"Roderich"},{"full_name":"Schulenburg, Hinrich","last_name":"Schulenburg","first_name":"Hinrich"}],"date_published":"2026-05-20T00:00:00Z","publication":"Nature Communications","file":[{"success":1,"file_id":"21936","date_updated":"2026-06-02T07:11:12Z","file_size":1276166,"date_created":"2026-06-02T07:11:12Z","content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"aa29f8806908dc0469dff21e2d5ad01f","file_name":"2026_NatureComm_Buchholz.pdf","creator":"dernst"}],"_id":"21928","scopus_import":"1","type":"journal_article","year":"2026","corr_author":"1","OA_type":"gold","department":[{"_id":"CaGu"}],"project":[{"_id":"bd6f94d1-d553-11ed-ba76-ae9f07250f74","grant_number":"E219","name":"Non-canonical antibiotic interactions"}],"publisher":"Springer Nature","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2026-06-02T07:11:12Z","oa":1,"quality_controlled":"1","article_number":"4487","OA_place":"publisher","acknowledgement":"We are very grateful to S.

The success of such treatment designs requires their robust efficacy across treatment conditions and a pathogen’s genomic diversity. This study found that an initial treatment with a β-lactam antibiotic causes robust cellular sensitization towards an aminoglycoside antibiotic across the high-risk human pathogen Pseudomonas aeruginosa, including resistant strains. This phenomenon of cellular sensitization, termed negative hysteresis, is modulated by the Cpx envelope stress response system and linked to membrane stress during growth. The increase in efficacy is achieved through a β-lactam induced elevated cellular uptake of the subsequently administered aminoglycoside. Negative hysteresis and the Cpx system are linked in several cases to the expression of synergistic drug interactions, thus enhancing efficacy of antibiotic combinations. Overall, our study identifies the phenomenon of negative hysteresis as a robustly inducible phenotype and thus a unique focus for optimizing antimicrobial therapy."}],"language":[{"iso":"eng"}],"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","has_accepted_license":"1","oa_version":"Published Version","day":"20","DOAJ_listed":"1","citation":{"apa":"Buchholz, F., Upterworth, L.

Although bacteria lack meiotic recombination, homologous recombination has been known to extensively shape their genomes. However, the mechanisms and ecological conditions sustaining frequent recombination in bacteria remain unclear. Using an Escherichia coli–P1 phage model system, we reveal how frequent recombination emerges from CRISPR-based herd immunity to a generalized transducing phage (DNA vector). Herd immunity maintains phage-susceptible donor bacteria, recipient immune bacteria, and transducing phage, which promotes chromosomal gene flow that exceeds spontaneous mutation by up to two orders of magnitude. Notably, recombination begins as bacterial cultures enter stationary phase, when canonical mutation supply through population growth and DNA replication is strongly reduced, and recombination can be reinitiated by brief fresh nutrient pulses. Genetic analysis showed that stationary-phase recombination requires recA, recB, and recG, connecting this process to a defined homologous recombination pathway, and suggests a plausible transcriptional regulatory link to transition to nutrient limitation. Bacterial herd immunity therefore has an unexpected evolutionary consequence: it can promote homologous recombination by turning phages into de facto pollinators. This mechanism can help explain how high rates of homologous recombination may be sustained across bacterial populations and suggests that bacterial immune systems can shape molecular evolution not only by blocking infection but also by regulating genetic exchange.","lang":"eng"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0737-4038"],"eissn":["1537-1719"]},"doi":"10.1093/molbev/msag238","tmp":{"short":"CC BY-NC (4.0)","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","image":"/images/cc_by_nc.png","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"has_accepted_license":"1","status":"public","citation":{"mla":"Payne, Pavel, et al. “Herd Immunity Underlies Homologous Recombination in Stationary Phase Bacteria.” <i>Molecular Biology and Evolution</i>, vol. 43, no. 10, msag238, Oxford University Press, 2026, doi:<a href=\"https://doi.org/10.1093/molbev/msag238\">10.1093/molbev/msag238</a>.","ieee":"P.

Decades-long efforts yielded TF-DNA interaction models that predict how strongly an individual TF binds arbitrary DNA sequences and how individual binding events on the CRE combine to affect gene expression. These insights can be synthesized into a global, biophysically realistic, and quantitative genotype–phenotype map for gene regulation, a ‘holy grail’ for the application of evolutionary theory. A global map provides a rare opportunity to simulate the long-term evolution of regulatory sequences and pose several fundamental questions: How long does it take to evolve CREs de novo? How many non-trivial regulatory functions exist in sequence space? How connected are they? For which regulatory architecture is CRE evolution most rapid and evolvable? In this article, the first of a two-part series, we briefly review the pertinent modeling and simulation efforts for a unique system that enables close, quantitative, and mechanistic links between biophysics, as well as systems, synthetic, and evolutionary biology."}],"language":[{"iso":"eng"}],"intvolume":"        99","acknowledgement":"We thank Nick Barton and Noa Ottilie Borst for essential contributions to this manuscript.\r\nE.M. acknowledges support from the APART-USA fellowship, jointly funded by the Austrian Academy of Sciences (ÖAW) and the Institute of Science and Technology Austria (ISTA).\r\nThis study was supported by the European Molecular Biology Laboratory (J.C.); the European Molecular Biology Laboratory Interdisciplinary Postdoc Programme (EIPOD) under the Marie Skłodowska-Curie Actions cofund (S.H.A.).","fulldoi":"https://doi.org/10.1016/j.gde.2026.102483","PlanS_conform":"1","ddc":["570"],"volume":99,"publisher":"Elsevier","publication_status":"epub_ahead","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","oa":1,"article_number":"102483","OA_place":"publisher","scopus_import":"1","type":"journal_article","year":"2026","corr_author":"1","department":[{"_id":"GradSch"},{"_id":"CaGu"},{"_id":"GaTk"}],"OA_type":"hybrid","author":[{"id":"776a6ed0-a053-11f0-8635-80b95e0e0d53","full_name":"Mascolo, Elia","orcid":"0000-0003-2977-7844","last_name":"Mascolo","first_name":"Elia"},{"last_name":"Körei","first_name":"Reka E","id":"50FDE43E-AA30-11E9-A72B-8A12E6697425","full_name":"Körei, Reka E"},{"full_name":"Herrera-Álvarez, Santiago","first_name":"Santiago","last_name":"Herrera-Álvarez"},{"first_name":"Calin C","last_name":"Guet","orcid":"0000-0001-6220-2052","full_name":"Guet, Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Crocker","first_name":"Justin","full_name":"Crocker, Justin"},{"id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","full_name":"Tkačik, Gašper","last_name":"Tkačik","orcid":"0000-0002-6699-1455","first_name":"Gašper"}],"date_published":"2026-05-09T00:00:00Z","publication":"Current Opinion in Genetics & Development","_id":"21983","title":"Long-term evolution of regulatory DNA sequences.

In contrast, basal expression at uninduced promoters is considered to be a dynamically inert mode of non-functional “promoter leakiness”, merely a byproduct of transcriptional regulation. Here, we investigate the basal expression mode of the mar operon, the main regulator of intrinsic multiple antibiotic resistance in Escherichia coli, and link its dynamic properties to the non-canonical, yet highly conserved start codon of marR across Enterobacteriaceae. Real-time, single-cell measurements across tens of generations reveal that basal expression consists of rare stochastic gene expression pulses, which maximize variability in wildtype and, surprisingly, transiently accelerate cellular elongation rates. Competition experiments show that basal expression confers fitness advantages to wildtype across several transitions between exponential and stationary growth by shortening lag times. The dynamically rich basal expression of the mar operon has likely been evolutionarily maintained for its role in growth homeostasis of Enterobacteria within the gut environment, thereby allowing other ancillary gene regulatory roles to evolve, e.g. control of costly-to-induce multi-drug efflux pumps. Understanding the complex selection forces governing genetic systems involved in intrinsic multi-drug resistance is crucial for effective public health measures.","lang":"eng"}],"_id":"19294","date_published":"2025-03-04T00:00:00Z","author":[{"last_name":"Jain","orcid":"0000-0002-3809-0449","first_name":"Kirti","id":"330F0278-F248-11E8-B48F-1D18A9856A87","full_name":"Jain, Kirti"},{"full_name":"Hauschild, Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","first_name":"Robert","last_name":"Hauschild","orcid":"0000-0001-9843-3522"},{"orcid":"0000-0003-1006-6639","last_name":"Bochkareva","first_name":"Olga","id":"C4558D3C-6102-11E9-A62E-F418E6697425","full_name":"Bochkareva, Olga"},{"first_name":"Roderich","orcid":"0000-0001-9480-5261","last_name":"Römhild","full_name":"Römhild, Roderich","id":"68E56E44-62B0-11EA-B963-444F3DDC885E"},{"id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","full_name":"Tkačik, Gašper","last_name":"Tkačik","orcid":"0000-0002-6699-1455","first_name":"Gašper"},{"orcid":"0000-0001-6220-2052","last_name":"Guet","first_name":"Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","full_name":"Guet, Calin C"}],"doi":"10.15479/AT:ISTA:19294","file":[{"date_updated":"2025-03-04T13:08:52Z","success":1,"file_id":"19295","date_created":"2025-03-04T13:08:52Z","file_size":269054,"content_type":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","access_level":"open_access","checksum":"11a5bab307a4e1e1598a1577d8a2fbb5","relation":"main_file","file_name":"Data1.xlsx","creator":"dernst"},{"file_id":"19296","success":1,"date_updated":"2025-03-04T13:08:52Z","file_size":87143,"date_created":"2025-03-04T13:08:52Z","access_level":"open_access","content_type":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","file_name":"Data2.xlsx","creator":"dernst","relation":"main_file","checksum":"3b057894322639f0c1e11fb2e84173e6"},{"file_size":129101,"date_created":"2025-03-04T13:08:52Z","date_updated":"2025-03-04T13:08:52Z","success":1,"file_id":"19297","checksum":"a551e1b79a138bb97ab96979aa475b3c","relation":"main_file","creator":"dernst","file_name":"Data3.xlsx","content_type":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","access_level":"open_access"},{"content_type":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","access_level":"open_access","checksum":"d6909c9bf111f859058082b1a2f970c4","relation":"main_file","creator":"dernst","file_name":"Data4.xlsx","date_updated":"2025-03-04T13:08:52Z","success":1,"file_id":"19298","file_size":86243,"date_created":"2025-03-04T13:08:52Z"},{"file_size":26049,"date_created":"2025-03-04T13:08:52Z","date_updated":"2025-03-04T13:08:52Z","file_id":"19299","success":1,"file_name":"Data5.xlsx","creator":"dernst","relation":"main_file","checksum":"e5725a3a118a3f06846104906c8792c7","access_level":"open_access","content_type":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"},{"success":1,"file_id":"19300","date_updated":"2025-03-04T13:08:52Z","file_size":7327253,"date_created":"2025-03-04T13:08:52Z","content_type":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","access_level":"open_access","relation":"main_file","checksum":"16763c127049f14bd587dc885677dce1","file_name":"RawData_2_3.xlsx","creator":"dernst"},{"access_level":"open_access","content_type":"text/plain","creator":"dernst","file_name":"Readme.txt","checksum":"2f3e1a368b4e3abc46bf37e02724f0f4","relation":"main_file","file_id":"19301","success":1,"date_updated":"2025-03-05T07:39:38Z","file_size":606,"date_created":"2025-03-05T07:39:38Z"}],"ddc":["570"],"month":"03","date_updated":"2026-05-20T08:33:07Z","article_processing_charge":"No","title":"Data for \"Pulsatile basal gene expression as a fitness determinant in bacteria\"","related_material":{"record":[{"id":"19626","relation":"used_in_publication","status":"public"}]},"date_created":"2025-03-04T13:27:21Z","fulldoi":"https://doi.org/10.15479/AT:ISTA:19294","OA_place":"repository","oa":1,"citation":{"apa":"Jain, K., Hauschild, R., Bochkareva, O., Römhild, R., Tkačik, G., &#38; Guet, C.

In contrast, basal expression at uninduced promoters is considered to be a dynamically inert mode of nonfunctional “promoter leakiness,” merely a byproduct of transcriptional regulation. Here, we investigate the basal expression mode of the mar operon, the main regulator of intrinsic multiple antibiotic resistance in Escherichia coli, and link its dynamic properties to the noncanonical, yet highly conserved start codon of marR across Enterobacteriaceae. Real-time, single-cell measurements across tens of generations reveal that basal expression consists of rare stochastic gene expression pulses, which maximize variability in wildtype and, surprisingly, transiently accelerate cellular elongation rates. Competition experiments show that basal expression confers fitness advantages to wildtype across several transitions between exponential and stationary growth by shortening lag times. The dynamically rich basal expression of the mar operon has likely been evolutionarily maintained for its role in growth homeostasis of Enterobacteria within the gut environment, thereby allowing other ancillary gene regulatory roles to evolve, e.g., control of costly-to-induce multidrug efflux pumps. Understanding the complex selection forces governing genetic systems involved in intrinsic multidrug resistance is crucial for effective public health measures.","lang":"eng"}],"doi":"10.1073/pnas.2413709122","publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"volume":122,"ddc":["570"],"acknowledged_ssus":[{"_id":"Bio"}],"fulldoi":"https://doi.org/10.1073/pnas.2413709122","related_material":{"record":[{"id":"19294","relation":"research_data","status":"public"}],"link":[{"url":"https://ista.ac.at/en/news/clockwork-just-for-antibiotic-resistance/","description":"News on ISTA website","relation":"press_release"}]},"acknowledgement":"K.J. thanks B.

Control of PPIs through optically or chemically responsive protein domains has had a profound impact on basic research and some clinical applications. Most chemogenetic methods induce the association, i.e., dimerization or oligomerization, of target proteins, whilst the few available dissociation approaches either break large oligomeric protein clusters or heteromeric complexes. Here, we have exploited the controlled dissociation of a homodimeric oxidoreductase from mycobacteria (MSMEG_2027) by its native cofactor, F420, which is not present in mammals, as a bioorthogonal monomerization switch. Using X-ray crystallography, we found that in the absence of F420 MSMEG_2027 forms a unique domain-swapped dimer that occludes the cofactor binding site. Rearrangement of the N-terminal helix upon F420 binding results in the dissolution of the dimer. We then showed that MSMEG_2027 can be fused to proteins of interest in human cells and applied it as a tool to induce and release MAPK/ERK signalling downstream of a chimeric fibroblast growth factor receptor 1 (FGFR1) tyrosine kinase. This F420-dependent chemogenetic de-homodimerization tool is stoichiometric and based on a single domain and thus represents a novel mechanism to investigate protein complexes in situ.","lang":"eng"}],"isi":1},{"date_created":"2025-06-22T22:02:06Z","title":"A bacterial toxin-antitoxin system as a native defence element against RNA phages","article_type":"original","article_processing_charge":"Yes (via OA deal)","month":"06","date_updated":"2025-09-30T13:38:08Z","file":[{"file_name":"2025_BiologyLetters_Nikolic.pdf","creator":"dernst","checksum":"016f644ed068f8609ded306ad26dbd3f","relation":"main_file","access_level":"open_access","content_type":"application/pdf","date_created":"2025-06-23T11:34:39Z","file_size":1850797,"date_updated":"2025-06-23T11:34:39Z","file_id":"19873","success":1}],"publication":"Biology Letters","author":[{"full_name":"Nikolic, Nela","id":"42D9CABC-F248-11E8-B48F-1D18A9856A87","first_name":"Nela","last_name":"Nikolic","orcid":"0000-0001-9068-6090"},{"full_name":"Pleska, Maros","id":"4569785E-F248-11E8-B48F-1D18A9856A87","first_name":"Maros","orcid":"0000-0001-7460-7479","last_name":"Pleska"},{"id":"2C471CFA-F248-11E8-B48F-1D18A9856A87","full_name":"Bergmiller, Tobias","orcid":"0000-0001-5396-4346","last_name":"Bergmiller","first_name":"Tobias"},{"orcid":"0000-0001-6220-2052","last_name":"Guet","first_name":"Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","full_name":"Guet, Calin C"}],"date_published":"2025-06-11T00:00:00Z","_id":"19857","ec_funded":1,"pmid":1,"OA_type":"hybrid","department":[{"_id":"CaGu"}],"project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","grant_number":"291734","call_identifier":"FP7","name":"International IST Postdoc Fellowship Programme"},{"call_identifier":"FWF","name":"Bacterial toxin-antitoxin systems as antiphage defense mechanisms","grant_number":"V00738","_id":"26956E74-B435-11E9-9278-68D0E5697425"}],"year":"2025","type":"journal_article","scopus_import":"1","corr_author":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","file_date_updated":"2025-06-23T11:34:39Z","publisher":"The Royal Society","publication_status":"published","quality_controlled":"1","article_number":"20250080","oa":1,"OA_place":"publisher","fulldoi":"https://doi.org/10.1098/rsbl.2025.0080","acknowledgement":"This work was supported by ISTFELLOW (People Program – Marie Curie Actions of the European Union’s Seventh Framework Program FP7 under REA grant agreement 291734), the FWF (Austrian Science Fund) Elise Richter Program project number V 738 and the Wellcome Trust Institutional Strategic Support Award (WT105618MA), to N.N.

Most known bacterial antiphage defence systems target phages with DNA genomes, which raises the question of how bacteria defend against phages with RNA genomes. Bacterial toxin–antitoxin systems that cleave intracellular RNA could potentially protect bacteria against RNA phages, but this has not been explored experimentally. In this study, we investigated the role of a model toxin–antitoxin system, MazEF, in protecting Escherichia coli against two RNA phage species. When challenged with these phages, the native presence of mazEF moderately reduced population susceptibility and increased the survival of individual E. coli cells. Genomic analysis further revealed an underrepresentation of the MazF cleavage site in genomes of RNA phages infecting E. coli, indicating selection against cleavage. These results show that, in addition to other physiological roles, RNA-degrading toxin–antitoxin systems may also help defend against RNA phages.","lang":"eng"}],"has_accepted_license":"1","status":"public","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"day":"11","external_id":{"pmid":["40494395"],"isi":["001505019800001"]},"oa_version":"Published Version","issue":"6","citation":{"ista":"Nikolic N, Pleska M, Bergmiller T, Guet CC. 2025.

More recently, it has been demonstrated that activation of the proton ATPs pump (H+-ATPs) promoting acidification of the apoplast is the principal mechanism by which auxin and other hormones such as brassinosteroids (BR) induce cell elongation. Despite these advances, the impact of this acidification on the mechanical properties of the cell wall remained largely unexplored.\r\n\r\nMethods: Here, we use elongation assays of Arabidopsis thaliana hypocotyls and Atomic Force Microscopy (AFM) to correlate hormone-induced tissue elongation and local changes in cell wall mechanical properties. Furthermore, employing transgenic lines over-expressing Pectin Methyl Esterase (PME), along with calcium chelators, we investigate the effect of pectin modification in hormone-driven cell elongation.\r\n\r\nResults: We demonstrate that acidification of apoplast is necessary and sufficient to induce cell elongation through promoting cell wall softening. Moreover, we show that enhanced PME activity can induce both cell wall softening or stiffening in extracellular calcium dependent-manner and that tight control of PME activity is required for proper hypocotyl elongation.\r\n\r\nDiscussion: Our results confirm a dual role of PME in plant cell elongation. However, further investigation is needed to assess the status of pectin following short- or long-term PME treatments in order to determine if pectin methyl-esterification might promote its degradation as well as the role of PME inhibitors upon PME induction."}],"isi":1,"language":[{"iso":"eng"}],"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","has_accepted_license":"1","oa_version":"Published Version","external_id":{"pmid":["40688689"],"isi":["001530690900001"]},"day":"04","DOAJ_listed":"1","citation":{"mla":"Gallemi, Marçal, et al. “Dual Role of Pectin Methyl Esterase Activity in the Regulation of Plant Cell Wall Biophysical Properties.” <i>Frontiers in Plant Science</i>, vol. 16, 1612366, Frontiers Media, 2025, doi:<a href=\"https://doi.org/10.3389/fpls.2025.1612366\">10.3389/fpls.2025.1612366</a>.","chicago":"Gallemi, Marçal, Juan C Montesinos López, Nikola Zarevski, Jan Pribyl, Petr Skládal, Edouard B Hannezo, and Eva Benková. “Dual Role of Pectin Methyl Esterase Activity in the Regulation of Plant Cell Wall Biophysical Properties.” <i>Frontiers in Plant Science</i>.

Here, we highlight some of the major sources of complexity that arise when relating molecular mechanisms to their evolutionary consequences and ask whether accounting for every mechanistic detail is important to accurately predict evolutionary outcomes. To do this, we developed a mechanistic model of a bacterial promoter regulated by 2 proteins, allowing us to connect any promoter genotype to 6 phenotypes that capture the dynamics of gene expression following an environmental switch. Accounting for the mechanisms that govern how this system works enabled us to provide an in-depth picture of how regulated bacterial promoters might evolve. More importantly, we used the model to explore which factors that contribute to the complexity of this system are essential for understanding its evolution, and which can be simplified without information loss. We found that several key evolutionary properties—the distribution of phenotypic and fitness effects of mutations, the evolutionary trajectories during selection for regulation—can be accurately captured without accounting for all, or even most, parameters of the system. Our findings point to the need for a mechanistic approach to studying evolution, as it enables tackling biological complexity and in doing so improves the ability to predict evolutionary outcomes."}],"isi":1,"language":[{"iso":"eng"}],"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","has_accepted_license":"1","oa_version":"Published Version","external_id":{"pmid":["39601269"],"isi":["001379194200001"]},"day":"01","citation":{"apa":"Grah, R., Guet, C.

I found that essential proteins of temperate phages\r\ncan interfere with potential hosts, indicating limitations to composability. I also designed a\r\nlysogeny reporter construct and characterize its behavior across various laboratory and\r\nenvironmental strains, finding differences in phage lambda lysogens, and potential\r\ninterference from prophages that already exist within the environmental strains.

As such, bacterial electrophysiology is fundamentally important for the bacterial life cycle, but it is often neglected and consequently, by and large, not understood. Arguably, the two main reasons for this are the complexity of measuring relevant variables in small cells with a cell envelope that contains the cell wall and the fact that, in a unicellular organism, relevant variables become intertwined in a nontrivial manner. To help give bacterial electrophysiology studies a firm footing, in this review, we go back to basics. We look first at the biophysics of bacterial membrane potential, and then at the approaches and models developed mostly for the study of neurons and eukaryotic mitochondria. We discuss their applicability to bacterial cells. Finally, we connect bacterial membrane potential with other relevant (electro)physiological variables and summarize methods that can be used to both measure and influence bacterial electrophysiology."}],"language":[{"iso":"eng"}],"intvolume":"        53","acknowledgement":"We would like to thank all members of the Pilizota lab, as well as Calin Guet, Orkun Soyer, Munehiro Asally, Peter Swain, and in particular Matt Scott and Ariel Amir, for their support, comments, and useful discussions.

As many different chemical compounds can induce this operon, identifying the parameters that govern the dynamics of its induction is crucial to better characterize the processes of tolerance and resistance. Most experiments have assumed that the properties of the mar transcriptional network can be inferred from population measurements. However, measurements from an asynchronous population of cells can mask underlying phenotypic variations of single cells. We monitored the activity of the mar promoter in single Escherichia coli cells in linear micro-colonies and established that the response to a steady level of inducer was most heterogeneous within individual colonies for an intermediate value of inducer. Specifically, sub-lineages defined by contiguous daughter-cells exhibited similar promoter activity, whereas activity was greatly variable between different sub-lineages. Specific sub-trees of uniform promoter activity persisted over several generations. Statistical analyses of the lineages suggest that the presence of these sub-trees is the signature of an inducible memory of the promoter state that is transmitted from mother to daughter cells. This single-cell study reveals that the degree of epigenetic inheritance changes as a function of inducer concentration, suggesting that phenotypic inheritance may be an inducible phenotype."}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1664-302X"]},"doi":"10.3389/fmicb.2023.1049255","ddc":["570"],"volume":14,"intvolume":"        14","acknowledgement":"This work was supported by NIH P50 award P50GM081892-02 to the University of Chicago, a catalyst grant from the Chicago Biomedical Consortium with support from The Searle Funds at The Chicago Community Trust to PC, and a Yen Fellowship to CCG.

Recent progress with experimental platforms and optogenetics has made it possible to expose each cell in an experiment to an individualised input and automatically record cellular responses over days with fine time resolution. However, methods to infer parameters of stochastic kinetic models from single-cell longitudinal data have generally been developed under the assumption that experimental data is sparse and that responses of cells to at most a few different input perturbations can be observed. Here, we investigate and compare different approaches for calculating parameter likelihoods of single-cell longitudinal data based on approximations of the chemical master equation (CME) with a particular focus on coupling the linear noise approximation (LNA) or moment closure methods to a Kalman filter. We show that, as long as cells are measured sufficiently frequently, coupling the LNA to a Kalman filter allows one to accurately approximate likelihoods and to infer model parameters from data even in cases where the LNA provides poor approximations of the CME. Furthermore, the computational cost of filtering-based iterative likelihood evaluation scales advantageously in the number of measurement times and different input perturbations and is thus ideally suited for data obtained from modern experimental platforms. To demonstrate the practical usefulness of these results, we perform an experiment in which single cells, equipped with an optogenetic gene expression system, are exposed to various different light-input sequences and measured at several hundred time points and use parameter inference based on iterative likelihood evaluation to parameterise a stochastic model of the system."}],"isi":1},{"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file_date_updated":"2022-05-02T06:26:26Z","publisher":"Springer Nature","publication_status":"published","quality_controlled":"1","oa":1,"article_number":"385","pmid":1,"department":[{"_id":"CaGu"}],"year":"2022","scopus_import":"1","type":"journal_article","publication":"Communications Biology","file":[{"file_size":2827723,"date_created":"2022-05-02T06:26:26Z","date_updated":"2022-05-02T06:26:26Z","file_id":"11342","success":1,"creator":"dernst","file_name":"2022_CommBiology_Glover.pdf","checksum":"7c6f76ab17393d650825cc240edc84b3","relation":"main_file","access_level":"open_access","content_type":"application/pdf"}],"author":[{"first_name":"Georgina","last_name":"Glover","full_name":"Glover, Georgina"},{"last_name":"Voliotis","first_name":"Margaritis","full_name":"Voliotis, Margaritis"},{"first_name":"Urszula","last_name":"Łapińska","full_name":"Łapińska, Urszula"},{"full_name":"Invergo, Brandon M.","last_name":"Invergo","first_name":"Brandon M."},{"full_name":"Soanes, Darren","last_name":"Soanes","first_name":"Darren"},{"last_name":"O’Neill","first_name":"Paul","full_name":"O’Neill, Paul"},{"full_name":"Moore, Karen","first_name":"Karen","last_name":"Moore"},{"first_name":"Nela","last_name":"Nikolic","orcid":"0000-0001-9068-6090","full_name":"Nikolic, Nela","id":"42D9CABC-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Petrov","first_name":"Peter","full_name":"Petrov, Peter"},{"last_name":"Milner","first_name":"David S.","full_name":"Milner, David S."},{"first_name":"Sumita","last_name":"Roy","full_name":"Roy, Sumita"},{"full_name":"Heesom, Kate","first_name":"Kate","last_name":"Heesom"},{"full_name":"Richards, Thomas A.","last_name":"Richards","first_name":"Thomas A."},{"full_name":"Tsaneva-Atanasova, Krasimira","last_name":"Tsaneva-Atanasova","first_name":"Krasimira"},{"last_name":"Pagliara","first_name":"Stefano","full_name":"Pagliara, Stefano"}],"date_published":"2022-04-20T00:00:00Z","_id":"11339","date_created":"2022-05-01T22:01:41Z","title":"Nutrient and salt depletion synergistically boosts glucose metabolism in individual Escherichia coli cells","article_type":"original","article_processing_charge":"No","date_updated":"2023-08-03T06:45:26Z","month":"04","day":"20","external_id":{"pmid":["35444215"],"isi":["000784143400001"]},"oa_version":"Published Version","citation":{"mla":"Glover, Georgina, et al. “Nutrient and Salt Depletion Synergistically Boosts Glucose Metabolism in Individual Escherichia Coli Cells.” <i>Communications Biology</i>, vol. 5, 385, Springer Nature, 2022, doi:<a href=\"https://doi.org/10.1038/s42003-022-03336-6\">10.1038/s42003-022-03336-6</a>.","ieee":"G.

In most cases growth rate is treated as a proximal metric for understanding the cellular metabolic status. However, changes in growth rate might not reflect metabolic variations in individuals responding to environmental fluctuations. Here we use single-cell microfluidics-microscopy combined with transcriptomics, proteomics and mathematical modelling to quantify the accumulation of glucose within Escherichia coli cells. In contrast to the current consensus, we reveal that environmental conditions which are comparatively unfavourable for growth, where both nutrients and salinity are depleted, increase glucose accumulation rates in individual bacteria and population subsets. We find that these changes in metabolic function are underpinned by variations at the translational and posttranslational level but not at the transcriptional level and are not dictated by changes in cell size. The metabolic response-characteristics identified greatly advance our fundamental understanding of the interactions between bacteria and their environment and have important ramifications when investigating cellular processes where salinity plays an important role."}],"fulldoi":"https://doi.org/10.1038/s42003-022-03336-6","acknowledgement":"G.G. was supported by an EPSRC DTP PhD studentship (EP/M506527/1).

MazF cleaves single-stranded ribonucleic acid (RNA) regions at adenine–cytosine–adenine (ACA) sequences in the bacterium Escherichia coli. The MazEF system has been used in various biotechnology and synthetic biology applications. In this study, we infer how ectopic mazF overexpression affects production of heterologous proteins. To this end, we quantified the levels of fluorescent proteins expressed in E. coli from reporters translated from the ACA-containing or ACA-less messenger RNAs (mRNAs). Additionally, we addressed the impact of the 5′-untranslated region of these reporter mRNAs under the same conditions by comparing expression from mRNAs that comprise (canonical mRNA) or lack this region (leaderless mRNA).\r\nResults: Flow cytometry analysis indicates that during mazF overexpression, fluorescent proteins are translated from the canonical as well as leaderless mRNAs. Our analysis further indicates that longer mazF overexpression generally increases the concentration of fluorescent proteins translated from ACA-less mRNAs, however it also substantially increases bacterial population heterogeneity. Finally, our results suggest that the strength and duration of mazF overexpression should be optimized for each experimental setup, to maximize the heterologous protein production and minimize the amount of phenotypic heterogeneity in bacterial populations, which is unfavorable in biotechnological processes."}],"has_accepted_license":"1","status":"public","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"day":"13","external_id":{"pmid":["35562780"]},"keyword":["General Biochemistry","Genetics and Molecular Biology","General Medicine"],"oa_version":"Published Version","citation":{"ista":"Nikolic N, Sauert M, Albanese TG, Moll I. 2022.
