Identification of growth insensitive to ABA3 (gia3), a recessive mutation affecting ABA Signaling for the control of early post-germination growth in Arabidopsis thaliana.

Abstract excerpt

The stress phytohormone ABA inhibits the developmental transition taking the mature embryo in the dry seed towards a young seedling. ABA also induces the accumulation of the basic leucine zipper (bZIP) transcription factor ABA-insensitive 5 (ABI5) which, apart from blocking endosperm rupture, also protects the embryo by stimulating the expression of late embryogenesis abundant (LEA) genes that conferred...
