Abstract excerpt
The Viviparous-1 (VP1) transcriptional activator of maize is required for abscisic acid induction of maturation-specific genes late in seed development leading to acquisition of desiccation tolerance and arrest in embryo growth. Here, we show that VP1 also inhibits induction of the germination-specific alpha-amylase genes in aleurone cells of the developing seed and thereby appears to be involved in preventing...
