Wang et al. explore how plants maintain apical etiolation. By Jiajun Wang (Southwest University, China), Haodong Chen (Tsinghua University, China), Xing Wang Deng (Peking University, China), Ning Wei (Southwest University, China) Background: Seeds germinate underneath the soil; to help the shoot…

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,…

Seed germination is can be described as having two phases depending on light availability, skoto- and photomorphogenesis. Skotomorphogenesis, which occurs while the seed is still buried, is characterized by the elongation of the coleoptile and the inhibition of the root system. When the seed reaches…

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.…

Upon germination in dark, plants adopt a strategy known as skotomorphogenesis, or etiolation, to protect the shoot apical meristem and cotyledon from damage while the seedling moves through the soil. The seedlings de-etiolate when they perceive light and the apical hook and cotyledon open. Wang et…
