RT   "The Viviparous-1 developmental gene of maize encodes a novel
RT   transcriptional activator.";
RL   Cell 66:895-905(1991).
CC   -!- FUNCTION: Transcriptional activator specifically required for
CC       expression of the maturation program in the seed development. Probably
CC       potentiates the response to the seed-specific hormone abscisic acid
CC       (ABA). May bind to DNA indirectly.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus.
CC   -!- TISSUE SPECIFICITY: Seed.
CC   -!- DEVELOPMENTAL STAGE: Between 10 and 30 days after pollination.
