Self-organizing development, such as flexible vasculature formation, depends on so-called auxin canalization, manifested by the gradual formation of auxin transport channels through feedback between auxin signalling and transport. Herein, we identify MAKR6 as an important, novel component in this feedback. MAKR6 expression accumulates strongly in vascular cells and is tightly regulated by auxin via the Aux/IAA-ARF-WRKY23 transcriptional network. MAKR6 is required for auxin canalization-dependent processes, including leaf venation, vasculature regeneration, and de novo auxin channel formation from local auxin sources. Mechanistically, MAKR6 interacts with the PIN1 auxin transporter, modulating its trafficking and polarization. MAKR6 also associates with and integrates two key receptor-like kinase complexes involved in canalization, TMK1/4 and the CAMEL-CANAR. Together, our study establishes MAKR6 as a multifaceted regulator that couples transcriptional auxin signalling to PIN1 repolarization and coordinates multiple RLK-mediated signalling pathways during canalization. This provides mechanistic insights into auxin canalization and exemplifies a framework for exploring similar regulatory nodes in other developmental contexts."}],"publication":"bioRxiv","date_created":"2026-06-13T16:57:07Z","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","date_updated":"2026-06-19T07:14:01Z","type":"preprint","OA_place":"repository","OA_type":"green","title":"MAKR6 integrates TMK and CAMEL/CANAR signalling for auxin canalization in Arabidopsis","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"has_accepted_license":"1"},{"oa":1,"OA_place":"repository","OA_type":"green","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"ABP1/ABL3-TMK1 cell-surface auxin signaling directly targets PIN2-mediated auxin fluxes for root gravitropism","date_updated":"2026-06-18T18:14:07Z","type":"preprint","abstract":[{"lang":"eng","text":"Phytohormone auxin and its directional transport mediate much of the remarkably plastic development of higher plants. Positive feedback between auxin signaling and transport is a key prerequisite for (i) self-organizing processes including vascular tissue formation and (ii) directional growth responses such as gravitropism. Here we identify a mechanism, by which auxin signaling directly targets PIN auxin transporters. Via the cell-surface ABP1-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 auxin receptor ABL3. Such positive feedback between cell-surface auxin signaling and PIN-mediated polar auxin transport is fundamental for robust root gravitropism and presumably also for other self-organizing developmental phenomena."}],"publication":"bioRxiv","date_created":"2025-03-13T08:36:48Z","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"oa_version":"Published Version","language":[{"iso":"eng"}],"corr_author":"1","month":"02","related_material":{"record":[{"id":"20656","relation":"later_version","status":"public"},{"status":"public","id":"19395","relation":"dissertation_contains"},{"relation":"dissertation_contains","id":"20364","status":"public"}]},"ec_funded":1,"day":"20","doi":"10.1101/2022.11.30.518503","department":[{"_id":"JiFr"},{"_id":"XiFe"}],"publication_status":"draft","acknowledgement":"We thank W.

the endomembrane system. The VLCFAs are synthesized in the endoplasmic reticulum by a heterotetrameric enzymatic complex including β-ketoacyl CoA reductase 1 (KCR1), whose mutant is lethal. Here, we describe the ectopic shoot meristems (esm) mutant, a viable kcr1 allele presumably affecting surface properties of the KCR1 protein. This kcr1-2 mutant shows reduced fatty acyl elongation that impacts VLCFAs. The kcr1-2 plants show severe defects during different stages of development, which all correlate with defects in polar localization and subcellular trafficking of PIN auxin transporters and resulting asymmetric auxin distribution. Detailed analysis of KCR1 expression and patterning defects in kcr1-2 suggests that KCR1 plays a role in delineating boundaries around meristematic and specialized differentiating tissues, including root and shoot meristems, initiating lateral roots, lateral root primordia, and trichomes. In these contexts, KCR1-produced VLCFAs may act in a non-cell-autonomous manner. Viable kcr1-2 represents a useful tool to study VLCFA roles in plant development and highlights VLCFAs as critical developmental factors at the interface of cell polarity and tissue development.","lang":"eng"}],"publication":"Plant Journal","date_created":"2025-08-17T22:01:36Z","publication_identifier":{"eissn":["1365-313X"],"issn":["0960-7412"]},"PlanS_conform":"1","file_date_updated":"2025-09-01T14:09:31Z","license":"https://creativecommons.org/licenses/by/4.0/","type":"journal_article","date_updated":"2026-04-07T11:52:02Z","article_type":"original","OA_place":"publisher","title":"Biosynthesis of very long-chain fatty acids is required for Arabidopsis auxin-mediated embryonic and post-embryonic development","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","OA_type":"hybrid","oa":1,"has_accepted_license":"1","status":"public","tmp":{"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","image":"/images/cc_by.png"},"citation":{"apa":"Babic, D., Abualia, R., Fiedler, L., Qi, L., Tellier, F., Smoljan, A., … Friml, J.

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."}],"date_created":"2025-11-19T09:44:31Z","publication":"Cell","publication_identifier":{"issn":["0092-8674"]},"PlanS_conform":"1","file_date_updated":"2025-11-24T10:55:18Z","type":"journal_article","date_updated":"2026-06-18T18:14:07Z","article_type":"original","OA_place":"publisher","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"ABP1/ABL3-TMK1 cell-surface auxin signaling targets PIN2-mediated auxin fluxes for root gravitropism","OA_type":"hybrid","has_accepted_license":"1","oa":1,"status":"public","tmp":{"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","image":"/images/cc_by.png"},"citation":{"short":"L.

These novel compounds did not show auxin-like activity, but instead antagonized physiological auxin effects. The DNS-labelled derivatives FL5 and FL6 showed strong anti-auxin activity in roots and hypocotyls, which also occurred at the level of gene transcription as confirmed by quantitative PCR analysis. 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. On the other hand, the strongest anti-auxin activity possessing compounds FL5 and FL6 could be useful to study binding mechanisms to auxin receptors and for manipulations of auxin-regulated processes.","lang":"eng"}],"publication":"Plant Growth Regulation","date_created":"2023-10-22T22:01:15Z","publication_identifier":{"issn":["0167-6903"],"eissn":["1573-5087"]},"file_date_updated":"2024-07-16T08:13:24Z","type":"journal_article","date_updated":"2024-07-16T08:13:39Z"},{"date_published":"2023-10-01T00:00:00Z","pmid":1,"article_processing_charge":"No","ddc":["580"],"publisher":"Elsevier","year":"2023","article_number":"102443","_id":"14313","external_id":{"pmid":["37666097"],"isi":["001080095300001"]},"issue":"10","isi":1,"author":[{"first_name":"Lukas","last_name":"Fiedler","full_name":"Fiedler, Lukas","id":"7c417475-8972-11ed-ae7b-8b674ca26986"},{"last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jiří","first_name":"Jiří","orcid":"0000-0002-8302-7596"}],"intvolume":"        75","volume":75,"department":[{"_id":"JiFr"}],"publication_status":"published","doi":"10.1016/j.pbi.2023.102443","day":"01","month":"10","corr_author":"1","language":[{"iso":"eng"}],"oa_version":"Submitted Version","quality_controlled":"1","citation":{"ama":"Fiedler L, Friml J.

The authors by no means endorse the rhetoric of Donald Rumsfeld or the 2003 invasion of Iraq by the United States. Nevertheless, Rumsfeld's quote led to both public and academic debates on the concept of known and unknown unknowns, which can be applied to the recent unexpected developments in the auxin signaling field. We thank Linlin Qi and Huihuang Chen for their suggestions on figure presentation and inspiring discussions of TIR1/AFB signaling. Finally, we thank Aroosa Hussain for discussion of Greek mythology.","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"Rapid auxin signaling: Unknowns old and new","article_type":"review","has_accepted_license":"1","oa":1,"publication":"Current Opinion in Plant Biology","date_created":"2023-09-10T22:01:11Z","publication_identifier":{"issn":["1369-5266"]},"abstract":[{"text":"To respond to auxin, the chief orchestrator of their multicellularity, plants evolved multiple receptor systems and signal transduction cascades. Despite decades of research, however, we are still lacking a satisfactory synthesis of various auxin signaling mechanisms. The chief discrepancy and historical controversy of the field is that of rapid and slow auxin effects on plant physiology and development. How is it possible that ions begin to trickle across the plasma membrane as soon as auxin enters the cell, even though the best-characterized transcriptional auxin pathway can take effect only after tens of minutes? Recently, unexpected progress has been made in understanding this and other unknowns of auxin signaling. We provide a perspective on these exciting developments and concepts whose general applicability might have ramifications beyond auxin signaling.","lang":"eng"}],"type":"journal_article","date_updated":"2025-09-09T12:54:16Z","file_date_updated":"2023-11-02T17:03:20Z"},{"oa":1,"has_accepted_license":"1","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"ABP1–TMK auxin perception for global phosphorylation and auxin canalization","file_date_updated":"2023-11-02T17:12:37Z","date_updated":"2026-04-07T11:52:15Z","type":"journal_article","abstract":[{"lang":"eng","text":"The phytohormone auxin triggers transcriptional reprogramming through a well-characterized perception machinery in the nucleus. 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."}],"publication_identifier":{"eissn":["1476-4687"],"issn":["0028-0836"]},"publication":"Nature","date_created":"2023-01-16T10:04:48Z","acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"LifeSc"}],"quality_controlled":"1","language":[{"iso":"eng"}],"oa_version":"Submitted Version","month":"09","corr_author":"1","related_material":{"record":[{"relation":"dissertation_contains","id":"19395","status":"public"},{"id":"20364","relation":"dissertation_contains","status":"public"}]},"ec_funded":1,"doi":"10.1038/s41586-022-05187-x","day":"15","publication_status":"published","department":[{"_id":"JiFr"},{"_id":"GradSch"},{"_id":"EvBe"},{"_id":"EM-Fac"}],"acknowledgement":"We acknowledge K.
