BIN2 signaling network constructed using proximity labeling and TurboID

The brassinosteroid (BR) signaling pathway is essential for plant growth and development. BRASSINOSTEROID-INSENSITIVE2 (BIN2) is a GSK3-like kinase, serving as a repressor of the BR signaling pathway. In the absence of BR, BIN2 phosphorylates BRASSINAZOLE-RESISTANT1 (BZR1) family transcription factors…

H2O2 regulates activity of the GSK3-like kinase BIN2

Lu et al. unravel a mechanism by which reactive oxygen species modulate brassinosteroid signaling through the GSK3-like kinase BIN2 Qing Lua,b, Eugenia Russinovaa,b a Department of Plant Biotechnology and Bioinformatics, Ghent University, 9052 Ghent, Belgium b Center for Plant Systems Biology,…

A new link between light and brassinosteroid signaling

Cao 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

Wang et al. identify a mechanism by which plants reduce growth under sucrose starvation conditions. Plant Cell. https://doi.org/10.1093/plcell/koab210 by Ping Wang and Yanhai Yin (Iowa State University)  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

Zhang 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.…
