A new link between light and brassinosteroid signaling
The Plant Cell: In a NutshellCao et al. demonstrate that the photomorphogenic repressors BBX28 and BBX29 enhance brassinosteroid signaling to promote hypocotyl elongation and cotyledon closure.
By Jing Cao and Fang Lin
Background: Light signals and brassinosteroids (BRs) are external stimuli and internal cues, respectively,…
An E3 ubiquitin ligase modulates brassinosteroid signaling by targeting the transcription factor BES1 to selective autophagy under sucrose starvation
The Plant Cell: In a NutshellWang et al. identify a mechanism by which plants reduce growth under sucrose starvation conditions. Plant Cell. https://doi.org/10.1093/plcell/koab210

Background: Plants fine-tune their growth and stress-response programs to adapt to the environment.…
NF-YCs mediate plant growth during the dark-to-light transition
The Plant Cell: In a NutshellZhang et al. uncover the roles of NF-YC transcription factors in repressing brassinosteroid biosynthesis and signaling to mediate photomorphogenesis in Arabidopsis.
Background: Seedlings, which germinate in the soil, generally undergo rapid hypocotyl elongation to seek light for growth and development.…
