The establishment of auxin concentration gradients, determines, among other processes, plant organ positioning and growth responses to environmental stimuli.\r\nHerein we report the synthesis of new NBD- or DNS-labelled IAA derivatives and the elucidation of their biological activity, fluorescence properties and subcellular accumulation patterns in planta. 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."}],"isi":1,"main_file_link":[{"url":"https://doi.org/10.1007/s10725-023-01083-0","open_access":"1"}],"day":"13","language":[{"iso":"eng"}],"author":[{"full_name":"Bieleszová, Kristýna","first_name":"Kristýna","last_name":"Bieleszová"},{"last_name":"Hladík","first_name":"Pavel","full_name":"Hladík, Pavel"},{"first_name":"Martin","last_name":"Kubala","full_name":"Kubala, Martin"},{"first_name":"Richard","last_name":"Napier","full_name":"Napier, Richard"},{"full_name":"Brunoni, Federica","last_name":"Brunoni","first_name":"Federica"},{"last_name":"Gelová","orcid":"0000-0003-4783-1752","first_name":"Zuzana","id":"0AE74790-0E0B-11E9-ABC7-1ACFE5697425","full_name":"Gelová, Zuzana"},{"first_name":"Lukas","last_name":"Fiedler","full_name":"Fiedler, Lukas","id":"7c417475-8972-11ed-ae7b-8b674ca26986"},{"first_name":"Ivan","last_name":"Kulich","full_name":"Kulich, Ivan","id":"57a1567c-8314-11eb-9063-c9ddc3451a54"},{"first_name":"Miroslav","last_name":"Strnad","full_name":"Strnad, Miroslav"},{"first_name":"Karel","last_name":"Doležal","full_name":"Doležal, Karel"},{"first_name":"Ondřej","last_name":"Novák","full_name":"Novák, Ondřej"},{"id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jiří","last_name":"Friml","orcid":"0000-0002-8302-7596","first_name":"Jiří"},{"last_name":"Žukauskaitė","first_name":"Asta","full_name":"Žukauskaitė, Asta"}],"publication_identifier":{"eissn":["1573-5087"],"issn":["0167-6903"]},"article_processing_charge":"Yes (via OA deal)","title":"New fluorescent auxin derivatives: anti-auxin activity and accumulation patterns in Arabidopsis thaliana","citation":{"short":"K.
