In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback regulation of auxin on the polarized localization of PIN auxin transporters in individual cells has been proposed as a self-organizing mechanism for coordinated tissue polarization, but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport remain unknown. We performed a microarray-based approach to find regulators of the auxin-induced PIN relocation in the Arabidopsis thaliana root. We identified a subset of a family of phosphatidylinositol transfer proteins (PITP), the PATELLINs (PATL). Here, we show that PATLs are expressed in partially overlapping cells types in different tissues going through mitosis or initiating differentiation programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis embryos, primary roots, lateral root primordia, and developing stomata. Higher order patl mutants display reduced PIN1 repolarization in response to auxin, shorter root apical meristem, and drastic defects in embryo and seedling development. This suggests PATLs redundantly play a crucial role in polarity and patterning in Arabidopsis."}],"date_created":"2018-12-11T11:49:10Z","publication_status":"published","publication":"Journal of Cell Science","language":[{"iso":"eng"}],"_id":"913","oa":1,"scopus_import":"1","file":[{"file_size":14925985,"relation":"main_file","file_id":"6299","file_name":"2017_adamowski_PATELLINS_are.pdf","creator":"dernst","content_type":"application/pdf","date_updated":"2020-07-14T12:48:15Z","date_created":"2019-04-12T08:46:32Z","access_level":"open_access","checksum":"bf156c20a4f117b4b932370d54cbac8c"}],"day":"29","publisher":"Company of Biologists","department":[{"_id":"JiFr"}],"isi":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","article_processing_charge":"No","oa_version":"Published Version","date_updated":"2023-09-26T15:47:50Z","publist_id":"6530","status":"public","external_id":{"isi":["000424842400019"]},"author":[{"full_name":"Tejos, Ricardo","first_name":"Ricardo","last_name":"Tejos"},{"last_name":"Rodríguez Furlán","first_name":"Cecilia","full_name":"Rodríguez Furlán, Cecilia"},{"first_name":"Maciek","orcid":"0000-0001-6463-5257","last_name":"Adamowski","full_name":"Adamowski, Maciek","id":"45F536D2-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Michael","last_name":"Sauer","full_name":"Sauer, Michael"},{"first_name":"Lorena","last_name":"Norambuena","full_name":"Norambuena, Lorena"},{"first_name":"Jirí","orcid":"0000-0002-8302-7596","last_name":"Friml","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"issue":"2","article_number":"jcs.204198","ddc":["581"],"doi":"10.1242/jcs.204198","has_accepted_license":"1","type":"journal_article","intvolume":"       131","citation":{"short":"R.
