ABSTRACT

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.
