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.…
