Positive feedback between auxin signaling and transport is a prerequisite for (1) self-organizing processes, including vascular tissue formation, and (2) directional growth responses such as gravitropism. Here, we identify a mechanism by which auxin signaling directly targets PIN auxin transporters. Via the cell-surface AUXIN-BINDING PROTEIN1 (ABP1)-TRANSMEMBRANE KINASE 1 (TMK1) receptor module, auxin rapidly induces phosphorylation and thus stabilization of PIN2. Following gravistimulation, initial auxin asymmetry activates autophosphorylation of the TMK1 kinase. This induces TMK1 interaction with and phosphorylation of PIN2, stabilizing PIN2 at the lower root side, thus reinforcing asymmetric auxin flow for root bending. Upstream of TMK1 in this regulation, ABP1 acts redundantly with the root-expressed ABP1-LIKE 3 (ABL3) auxin receptor. Such positive feedback between cell-surface auxin signaling and PIN-mediated polar auxin transport is fundamental for robust root gravitropism and presumably for other self-organizing developmental phenomena."}],"status":"public","date_published":"2025-10-30T00:00:00Z","department":[{"_id":"JiFr"},{"_id":"XiFe"}]},{"oa":1,"article_processing_charge":"No","corr_author":"1","fulldoi":"https://doi.org/10.1101/2022.11.30.518503","doi":"10.1101/2022.11.30.518503","publication_status":"draft","ddc":["580"],"month":"02","OA_type":"green","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"language":[{"iso":"eng"}],"ec_funded":1,"project":[{"name":"Tracing Evolution of Auxin Transport and Polarity in Plants","grant_number":"742985","_id":"261099A6-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"_id":"26538374-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"I03630","name":"Molecular mechanisms of endocytic cargo recognition in plants"},{"grant_number":"291734","name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7","_id":"25681D80-B435-11E9-9278-68D0E5697425"},{"_id":"26060676-B435-11E9-9278-68D0E5697425","name":"Cell surface receptor complexes for auxin signaling in plants","grant_number":"ALTF 985-2016"}],"author":[{"full_name":"Rodriguez Solovey, Lesia","id":"3922B506-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7244-7237","first_name":"Lesia","last_name":"Rodriguez Solovey"},{"id":"7c417475-8972-11ed-ae7b-8b674ca26986","last_name":"Fiedler","first_name":"Lukas","full_name":"Fiedler, Lukas"},{"id":"5c243f41-03f3-11ec-841c-96faf48a7ef9","last_name":"Zou","first_name":"Minxia","full_name":"Zou, Minxia"},{"id":"e3fdddd5-f6e0-11ea-865d-ca99ee6367f4","first_name":"Caterina","last_name":"Giannini","full_name":"Giannini, Caterina"},{"full_name":"Monzer, Aline","id":"2DB5D88C-D7B3-11E9-B8FD-7907E6697425","first_name":"Aline","last_name":"Monzer"},{"id":"60466724-5355-11ee-ae5a-fa55e8f99c3d","first_name":"Dmitrii","last_name":"Vladimirtsev","full_name":"Vladimirtsev, Dmitrii"},{"last_name":"Randuch","first_name":"Marek","id":"6ac4636d-15b2-11ec-abd3-fb8df79972ae","full_name":"Randuch, Marek"},{"last_name":"Yu","first_name":"Yongfan","full_name":"Yu, Yongfan"},{"orcid":"0000-0003-4783-1752","first_name":"Zuzana","last_name":"Gelová","id":"0AE74790-0E0B-11E9-ABC7-1ACFE5697425","full_name":"Gelová, Zuzana"},{"id":"362BF7FE-F248-11E8-B48F-1D18A9856A87","last_name":"Verstraeten","first_name":"Inge","orcid":"0000-0001-7241-2328","full_name":"Verstraeten, Inge"},{"last_name":"Hajny","first_name":"Jakub","orcid":"0000-0003-2140-7195","id":"4800CC20-F248-11E8-B48F-1D18A9856A87","full_name":"Hajny, Jakub"},{"full_name":"Chen, Meng","last_name":"Chen","first_name":"Meng"},{"orcid":"0000-0002-0471-8285","last_name":"Tan","first_name":"Shutang","id":"2DE75584-F248-11E8-B48F-1D18A9856A87","full_name":"Tan, Shutang"},{"full_name":"Hörmayer, Lukas","orcid":"0000-0001-8295-2926","first_name":"Lukas","last_name":"Hörmayer","id":"2EEE7A2A-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Li","first_name":"Lanxin","orcid":"0000-0002-5607-272X","id":"367EF8FA-F248-11E8-B48F-1D18A9856A87","full_name":"Li, Lanxin"},{"first_name":"Maria Mar","last_name":"Marques-Bueno","full_name":"Marques-Bueno, Maria Mar"},{"id":"32ff3c64-04a0-11f0-a50f-d0c45bfac466","last_name":"Quddoos","first_name":"Zainab","full_name":"Quddoos, Zainab"},{"full_name":"Molnar, Gergely","last_name":"Molnar","first_name":"Gergely","id":"34F1AF46-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Xu, Tongda","last_name":"Xu","first_name":"Tongda"},{"id":"57a1567c-8314-11eb-9063-c9ddc3451a54","last_name":"Kulich","first_name":"Ivan","full_name":"Kulich, Ivan"},{"full_name":"Jaillais, Yvon","first_name":"Yvon","last_name":"Jaillais"},{"full_name":"Friml, Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","last_name":"Friml","first_name":"Jiří"}],"year":"2025","main_file_link":[{"url":"https://doi.org/10.1101/2022.11.30.518503","open_access":"1"}],"oa_version":"Published Version","date_updated":"2026-10-11T22:30:07Z","OA_place":"repository","publication":"bioRxiv","related_material":{"record":[{"status":"public","id":"20656","relation":"later_version"},{"relation":"dissertation_contains","id":"19395","status":"public"},{"id":"20364","relation":"dissertation_contains","status":"public"}]},"status":"public","department":[{"_id":"JiFr"},{"_id":"XiFe"}],"date_published":"2025-02-20T00:00:00Z","acknowledgement":"We thank W.

The auxin antagonism of our derivatives was further demonstrated in vitro using an SPR-based binding assay. The NBD-labelled compound FL4 with the best fluorescence properties proved to be unsuitable to study auxin accumulation patterns in planta.

By contrast, mechanisms that underlie fast effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4. Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required for the auxin-induced ultrafast global phospho-response and for downstream processes that include the activation of H+-ATPase and accelerated cytoplasmic streaming. abp1 and tmk mutants cannot establish auxin-transporting channels and show defective auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that lacks the capacity to bind auxin is unable to complement these defects in abp1 mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface signalling, which mediates the global phospho-response and auxin canalization."}],"has_accepted_license":"1","file_date_updated":"2023-11-02T17:12:37Z","acknowledgement":"We acknowledge K.

A possible candidate for a component of additional auxin perception mechanisms is the AUXIN BINDING PROTEIN 1 (ABP1), whose function in planta remains unclear.\r\nHere we combined expression analysis with gain- and loss-of-function approaches to analyze the role of ABP1 in plant development. ABP1 shows a broad expression largely overlapping with, but not regulated by, transcriptional auxin response activity. Furthermore, ABP1 activity is not essential for the transcriptional auxin signaling. Genetic in planta analysis revealed that abp1 loss-of-function mutants show largely normal development with minor defects in bolting. On the other hand, ABP1 gain-of-function alleles show a broad range of growth and developmental defects, including root and hypocotyl growth and bending, lateral root and leaf development, bolting, as well as response to heat stress. At the cellular level, ABP1 gain-of-function leads to impaired auxin effect on PIN polar distribution and affects BFA-sensitive PIN intracellular aggregation.\r\nThe gain-of-function analysis suggests a broad, but still mechanistically unclear involvement of ABP1 in plant development, possibly masked in abp1 loss-of-function mutants by a functional redundancy."}],"type":"journal_article","citation":{"ama":"Gelová Z, Gallei MC, Pernisová M, et al.

Although their Histidine Kinase receptors are substantially localised to the endoplasmic reticulum, cellular sites of cytokinin perception and importance of spatially heterogeneous cytokinin distribution continue to be debated. Here we show that cytokinin perception by plasma membrane receptors is an effective additional path for cytokinin response. Readout from a Two Component Signalling cytokinin-specific reporter (TCSn::GFP) closely matches intracellular cytokinin content in roots, yet we also find cytokinins in extracellular fluid, potentially enabling action at the cell surface. Cytokinins covalently linked to beads that could not pass the plasma membrane increased expression of both TCSn::GFP and Cytokinin Response Factors. Super-resolution microscopy of GFP-labelled receptors and diminished TCSn::GFP response to immobilised cytokinins in cytokinin receptor mutants, further indicate that receptors can function at the cell surface. We argue that dual intracellular and surface locations may augment flexibility of cytokinin responses.","lang":"eng"}],"status":"public","article_number":"4284","department":[{"_id":"JiFr"}],"date_published":"2020-08-27T00:00:00Z","quality_controlled":"1","date_updated":"2026-04-03T09:25:48Z","oa_version":"Published Version","publisher":"Springer Nature","publication":"Nature Communications","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"year":"2020","external_id":{"pmid":["32855409"],"isi":["000567931000001"]},"volume":11,"file":[{"date_updated":"2020-12-10T12:23:56Z","checksum":"5b96f39b598de7510cfefefb819b9a6d","file_id":"8936","success":1,"file_size":3526415,"file_name":"2020_NatureComm_Antoniadi.pdf","access_level":"open_access","content_type":"application/pdf","creator":"dernst","relation":"main_file","date_created":"2020-12-10T12:23:56Z"}],"acknowledged_ssus":[{"_id":"Bio"}],"ddc":["580"],"publication_status":"published","article_type":"original","intvolume":"        11","month":"08","project":[{"_id":"26538374-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"I03630","name":"Molecular mechanisms of endocytic cargo recognition in plants"},{"name":"Tracing Evolution of Auxin Transport and Polarity in Plants","grant_number":"742985","call_identifier":"H2020","_id":"261099A6-B435-11E9-9278-68D0E5697425"}],"ec_funded":1,"language":[{"iso":"eng"}],"author":[{"full_name":"Antoniadi, Ioanna","last_name":"Antoniadi","first_name":"Ioanna"},{"full_name":"Novák, Ondřej","last_name":"Novák","first_name":"Ondřej"},{"id":"0AE74790-0E0B-11E9-ABC7-1ACFE5697425","orcid":"0000-0003-4783-1752","first_name":"Zuzana","last_name":"Gelová","full_name":"Gelová, Zuzana"},{"full_name":"Johnson, Alexander J","orcid":"0000-0002-2739-8843","first_name":"Alexander J","last_name":"Johnson","id":"46A62C3A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Plíhal, Ondřej","last_name":"Plíhal","first_name":"Ondřej"},{"full_name":"Simerský, Radim","first_name":"Radim","last_name":"Simerský"},{"full_name":"Mik, Václav","last_name":"Mik","first_name":"Václav"},{"full_name":"Vain, Thomas","last_name":"Vain","first_name":"Thomas"},{"first_name":"Eduardo","last_name":"Mateo-Bonmatí","full_name":"Mateo-Bonmatí, Eduardo"},{"full_name":"Karady, Michal","last_name":"Karady","first_name":"Michal"},{"full_name":"Pernisová, Markéta","last_name":"Pernisová","first_name":"Markéta"},{"first_name":"Lenka","last_name":"Plačková","full_name":"Plačková, Lenka"},{"full_name":"Opassathian, Korawit","last_name":"Opassathian","first_name":"Korawit"},{"full_name":"Hejátko, Jan","last_name":"Hejátko","first_name":"Jan"},{"full_name":"Robert, Stéphanie","last_name":"Robert","first_name":"Stéphanie"},{"full_name":"Friml, Jiří","first_name":"Jiří","last_name":"Friml","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Doležal, Karel","last_name":"Doležal","first_name":"Karel"},{"full_name":"Ljung, Karin","first_name":"Karin","last_name":"Ljung"},{"full_name":"Turnbull, Colin","last_name":"Turnbull","first_name":"Colin"}],"pmid":1,"publication_identifier":{"eissn":["2041-1723"]},"oa":1,"fulldoi":"https://doi.org/10.1038/s41467-020-17700-9","article_processing_charge":"No","doi":"10.1038/s41467-020-17700-9"},{"department":[{"_id":"JiFr"}],"date_published":"2019-04-11T00:00:00Z","status":"public","abstract":[{"lang":"eng","text":"The plant hormone auxin has crucial roles in almost all aspects of plant growth and development. Concentrations of auxin vary across different tissues, mediating distinct developmental outcomes and contributing to the functional diversity of auxin. However, the mechanisms that underlie these activities are poorly understood. Here we identify an auxin signalling mechanism, which acts in parallel to the canonical auxin pathway based on the transport inhibitor response1 (TIR1) and other auxin receptor F-box (AFB) family proteins (TIR1/AFB receptors)1,2, that translates levels of cellular auxin to mediate differential growth during apical-hook development. This signalling mechanism operates at the concave side of the apical hook, and involves auxin-mediated C-terminal cleavage of transmembrane kinase 1 (TMK1). The cytosolic and nucleus-translocated C terminus of TMK1 specifically interacts with and phosphorylates two non-canonical transcriptional repressors of the auxin or indole-3-acetic acid (Aux/IAA) family (IAA32 and IAA34), thereby regulating ARF transcription factors. In contrast to the degradation of Aux/IAA transcriptional repressors in the canonical pathway, the newly identified mechanism stabilizes the non-canonical IAA32 and IAA34 transcriptional repressors to regulate gene expression and ultimately inhibit growth. The auxin–TMK1 signalling pathway originates at the cell surface, is triggered by high levels of auxin and shares a partially overlapping set of transcription factors with the TIR1/AFB signalling pathway. This allows distinct interpretations of different concentrations of cellular auxin, and thus enables this versatile signalling molecule to mediate complex developmental outcomes."}],"_id":"6259","has_accepted_license":"1","file_date_updated":"2020-11-13T07:37:41Z","citation":{"ieee":"M.
