Auxin is directionally transported from cell to cell by the action of specific auxin influx [AUXIN-RESISTANT1 (AUX1)] and efflux [PIN-FORMED (PIN)] transport regulators, whose polar, subcellular localizations are aligned with the direction of the auxin flow. Auxin itself regulates its own transport by modulation of the expression and subcellular localization of the auxin transporters. Increased auxin levels promote the transcription of PIN2 and AUX1 genes as well as stabilize PIN proteins at the plasma membrane, whereas prolonged auxin exposure increases the turnover of PIN proteins and their degradation in the vacuole. In this study, we applied a forward genetic approach, to identify molecular components playing a role in the auxin-mediated degradation. We generated EMS-mutagenized Arabidopsis PIN2::PIN2:GFP, AUX1::AUX1:YFP eir1aux1 populations and designed a screen for mutants with persistently strong fluorescent signals of the tagged PIN2 and AUX1 after prolonged treatment with the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D). This approach yielded novel auxin degradation mutants defective in trafficking and degradation of PIN2 and AUX1 proteins and established a role for auxin-mediated degradation in plant development."}],"oa_version":"Preprint","oa":1,"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","date_created":"2018-12-11T11:53:12Z","publisher":"Springer","scopus_import":1,"quality_controlled":"1","title":"A forward genetic screen for new regulators of auxin mediated degradation of auxin transport proteins in Arabidopsis thaliana","status":"public","has_accepted_license":"1","publication":"Journal of Plant Growth Regulation","author":[{"full_name":"Zemová, Radka","first_name":"Radka","last_name":"Zemová"},{"full_name":"Zwiewka, Marta","last_name":"Zwiewka","first_name":"Marta"},{"full_name":"Bielach, Agnieszka","last_name":"Bielach","first_name":"Agnieszka"},{"last_name":"Robert","first_name":"Hélène","full_name":"Robert, Hélène"},{"orcid":"0000-0002-8302-7596","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jirí","last_name":"Friml"}],"page":"465 - 476","doi":"10.1007/s00344-015-9553-2","citation":{"mla":"Zemová, Radka, et al. “A Forward Genetic Screen for New Regulators of Auxin Mediated Degradation of Auxin Transport Proteins in Arabidopsis Thaliana.” <i>Journal of Plant Growth Regulation</i>, vol. 35, no. 2, Springer, 2016, pp. 465–76, doi:<a href=\"https://doi.org/10.1007/s00344-015-9553-2\">10.1007/s00344-015-9553-2</a>.","ieee":"R.
