  text: 'Premise of the study: To reach favorable conditions for photosynthesis, seedlings
    grow upward when deprived of light upon underground germination. 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.'
