Phytochrome B and REVEILLE1/2-mediated signalling controls seed dormancy and germination in Arabidopsis

Abstract

Seed dormancy prevents germination under adverse environmental conditions. Here the authors show that the RVE1 and RVE2 transcription factors suppress biosynthesis of the germination-promoting hormone GA and act downstream of phytochrome signalling to promote dormancy and repress light-induced germination.
