Other claims from this paper (5)
- Mechanism Cytokinin inhibition of hypocotyl elongation is largely independent of ethylene.
- Mechanism The cytokinin signal is mainly mediated by ARABIDOPSIS HISTIDINE KINASE3.
- Mechanism The cytokinin signal is mediated by ARABIDOPSIS RESPONSE REGULATOR1 together with ARR12.
- Intervention effect Mutation of COP1, DE-ETIOLATED1, or CYTOKININ INSENSITIVE4/COP10 makes plants insensitive to cytokinin.
- Mechanism The light-signaling factors are indispensable for transcriptional response during cytokinin-induced de-etiolation.
