Abstract

Seed thermoinhibition protects emerging seedlings from thermodamage by preventing seed germination at elevated temperatures. It had remained unknown how a seed fine-tunes its germination in response to temperature. Recently, Piskurewicz et al. demonstrated that endosperm phyB senses increased temperature, thereby facilitating PIF3-mediated abscisic acid (ABA) accumulation to inhibit germination and embryo elongation.

摘要

种子热抑制通过阻止种子在高温下发芽来保护新出现的幼苗免受热损伤。种子如何根据温度微调其发芽过程一直不为人知。最近，皮斯库雷维茨等人证明，胚乳中的phyB感知温度升高，从而促进PIF3介导的脱落酸（ABA）积累，以抑制发芽和胚轴伸长。
