Abstract excerpt

Abscisic acid (ABA) is an important phytohormone regulating seed dormancy and germination. DELAY OF GERMINATION 1 (DOG1) is a pivotal regulator of seed dormancy and regulates the ABA response by binding with ABA HYPERSENSITIVE GERMINATION 1 (AHG1) and heme. However, to date, the molecular function and regulatory mechanisms of DOG1 remain unclear, including the relationship between DOG1 and the ABA response. Here,...
