During the mid- to late phase of seed development, the embryo and the aleurone tissue undergo a maturation process, whereby each becomes dormant or quiescent and acquires the ability to tolerate desiccation. The maturation process is associated with the accumulation of characteristic sets of mRNAs and proteins, which are products of the so-called LEA (Late Embryogenesis Abundant protein) genes (Baker et al. 1988, Skriver and Mundy 1990). The phytohormone ABA plays key roles in the control of these events (McCarty 1995, Leung and Giraudat 1998). Genetic loci have been identified in Arabidopsis and maize that are required for the control of maturation processes. The viviparous1 (vp1) mutant of maize has been characterized as an ABA-insensitive mutant, in which various events during seed maturation are blocked (McCarty et al. 1991, Robichaud et al. 1980). At the molecular level, the vp1 mutant fails to accumulate mRNAs of ABA-regulated LEA genes, such as Rab28 (Pla et al. 1989) and the maize homologue of the wheat Em gene (McCarty et al. 1991), as well as the genes for globulin storage proteins (Kriz et al. 1990). The Vp1 gene encodes a transcription factor that can activate the transcription of maturation-associated genes(McCarty et al. 1991, Hattori et al. 1992). | During the mid- to late phase of seed development, the embryo and the aleurone tissue undergo a maturation process, whereby each becomes dormant or quiescent and acquires the ability to tolerate desiccation.

During the mid- to late phase of seed development, the embryo and the aleurone tissue undergo a maturation process, whereby each becomes dormant or quiescent and acquires the ability to tolerate desiccation. The maturation process is associated with the accumulation of characteristic sets of mRNAs and proteins, which are products of the so-called LEA (Late Embryogenesis Abundant protein) genes (Baker et al. 1988, Skriver and Mundy 1990). The phytohormone ABA plays key roles in the control of these events (McCarty 1995, Leung and Giraudat 1998). Genetic loci have been identified in Arabidopsis and maize that are required for the control of maturation processes. The viviparous1 (vp1) mutant of maize has been characterized as an ABA-insensitive mutant, in which various events during seed maturation are blocked (McCarty et al. 1991, Robichaud et al. 1980). At the molecular level, the vp1 mutant fails to accumulate mRNAs of ABA-regulated LEA genes, such as Rab28 (Pla et al. 1989) and the maize homologue of the wheat Em gene (McCarty et al. 1991), as well as the genes for globulin storage proteins (Kriz et al. 1990). The Vp1 gene encodes a transcription factor that can activate the transcription of maturation-associated genes(McCarty et al. 1991, Hattori et al. 1992).
In Arabidopsis, ABI3, one of the genes required for ABA response in seeds is known to be orthologous to maize VP1 (Giraudat et al. 1992). Mutant seeds with severe abi3 alleles show vivipary and block the expression of LEA and storage protein genes (Parcy et al. 1994). Parcy et al.
