Multilevel regulations of PIN activity under internal and external cues are complicated; however, the underlying molecular mechanism remains elusive. Here we demonstrate that 3’-Phosphoinositide-Dependent Protein Kinase1 (PDK1), which is conserved in plants and mammals, functions as a molecular hub integrating the upstream lipid signalling and the downstream substrate activity through phosphorylation. Genetic analysis uncovers that loss-of-function Arabidopsis mutant pdk1.1 pdk1.2 exhibits a plethora of abnormalities in organogenesis and growth, due to the defective PIN-dependent auxin transport. Further cellular and biochemical analyses reveal that PDK1 phosphorylates D6 Protein Kinase to facilitate its activity towards PIN proteins. Our studies establish a lipid-dependent phosphorylation cascade connecting membrane composition-based cellular signalling with plant growth and patterning by regulating morphogenetic auxin fluxes.","lang":"eng"}],"external_id":{"isi":["000531787500006"],"pmid":["32393881"]},"volume":6,"project":[{"grant_number":"742985","name":"Tracing Evolution of Auxin Transport and Polarity in Plants","_id":"261099A6-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"_id":"256FEF10-B435-11E9-9278-68D0E5697425","name":"Long Term Fellowship","grant_number":"723-2015"}],"status":"public","pmid":1,"publication":"Nature Plants","publication_status":"published","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1101/755504"}],"oa":1,"article_type":"original","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"intvolume":"         6","month":"05","article_processing_charge":"No","doi":"10.1038/s41477-020-0648-9","date_created":"2020-03-21T16:34:16Z","date_published":"2020-05-01T00:00:00Z","_id":"7600","ec_funded":1,"publisher":"Springer Nature","scopus_import":"1","oa_version":"Preprint","quality_controlled":"1","date_updated":"2023-08-18T07:05:57Z","day":"01","type":"journal_article","related_material":{"link":[{"url":"https://doi.org/10.1038/s41477-020-0719-y","relation":"erratum"}]},"year":"2020","publication_identifier":{"eissn":["20550278"]},"page":"556-569"}
