To direct their growth, they use their negative gravitropic capacity. Negative gravitropism is under tight control of multiple hormones. • Methods: By counting the number of standing plants in a population or by real time monitoring of the reorientation of gravistimulated seedlings of Arabidopsis thaliana, we evaluated the negative gravitropism of ethylene or brassinosteroid (BR) treated plants. Meta-analysis of transcriptomic data on AUX / IAA genes was gathered, and subsequent mutant analysis was performed. • Key results: Ethylene and BR have opposite effects in regulating shoot gravitropism. Lack of BR enhances gravitropic reorientation in 2-d-old seedlings, whereas ethylene does not. Lack of ethylene signaling results in enhanced BR sensitivity. Ethylene and BRs regulate overlapping sets of AUX / IAA genes. BRs regulate a wider range of auxin signaling components than ethylene. • Conclusions: Upward growth in seedlings depends strongly on the internal hormonal balance. Endogenous ethylene stimulates, whereas BRs reduce negative gravitropism in a manner that depends on the function of different, yet overlapping sets of auxin signaling components."}],"publication":"American Journal of Botany","issue":"1","publication_status":"published","title":"Brassinosteroid control of shoot gravitropism interacts with ethylene and depends on auxin signaling components","quality_controlled":0,"doi":"10.3732/ajb.1200264","author":[{"first_name":"Filip","full_name":"Vandenbussche, Filip","last_name":"Vandenbussche"},{"full_name":"Callebert, Pieter","first_name":"Pieter","last_name":"Callebert"},{"first_name":"Petra","full_name":"Žádníková, Petra","last_name":"Žádníková"},{"first_name":"Eva","full_name":"Eva Benková","orcid":"0000-0002-8510-9739","last_name":"Benková","id":"38F4F166-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Dominique","full_name":"Van Der Straeten, Dominique","last_name":"Van Der Straeten"}],"_id":"2877","date_created":"2018-12-11T12:00:06Z","month":"01","citation":{"chicago":"Vandenbussche, Filip, Pieter Callebert, Petra Žádníková, Eva Benková, and Dominique Van Der Straeten. “Brassinosteroid Control of Shoot Gravitropism Interacts with Ethylene and Depends on Auxin Signaling Components.” <i>American Journal of Botany</i>.
