“…Osvpl transcripts were not detected in the shoot tissues. Although we have not carried out an analysis with other tissues, this is consistent with the seed specific phenotypes of the vpl mutants and the results of transcript analyses performed with maize [9].…”

“…The vpl mutant is also blocked in the synthesis of anthocyanin in the embryo and the aleurone tissues [11]. Transcript analyses of the vpl mutant seeds have revealed that Vpl controls the steady-state levels of the transcript of the regulatory gene C1 for the anthocyanin pathway and ABA-regulated genes such as the maize homologue of the wheat Em gene [9]. The Vpl gene [9] and its cDNA [9,10] have been cloned.…”

Sequence and functional analyses of the rice gene homologous to the maize Vp1

The homologous gene of the maize Vp1 gene was isolated from rice (Oryza sativa). Sequence analysis revealed that the rice Vp1 gene (Osvp1) encodes a protein of 728 amino acids and is interupted by 5 introns at positions identical to those of the maize gene. Osvp1 transcript was detected in developing embryo as early as 10 days after flowering and decreased toward maturity. Osvp1 transcript was also detected in dry as well as imbided mature embryos. The ability of Osvp1 gene product to activate a target gene was shown by transient expression experiments in rice suspension-cultured cell protoplasts using a reporter gene construct carrying the bacterial beta-glucuronidase (GUS) gene fused to the promoter of OsEm gene, the rice homologue of the wheat Em gene.

“…Also, vpl mutations were shown to inhibit the anthocyanin biosynthetic pathway only in embryo and aleurone tissues [25,134]. Molecular cloning of the VPI [102] and ABI3 [45] genes provided a simple explanation for this specificity in that neither gene is found to be expressed in vegetative tissues [45,101,102,122]. The ABI3 gene is transiently expressed beyond seed germination in young seedlings, but this expression is strictly confined to the organs of embryonic origin (cotyledons and hypocotyl) [122].…”

Current advances in abscisic acid action and signalling

Abscisic acid (ABA) participates in the control of diverse physiological processes. The characterization of deficient mutants has clarified the ABA biosynthetic pathway in higher plants. Deficient mutants also lead to a revaluation of the extent of ABA action during seed development and in the response of vegetative tissues to environmental stress. Although ABA receptor(s) have not yet been identified, considerable progress has been recently made in the characterization of more downstream elements of the ABA regulatory network. ABA controls stomatal aperture by rapidly regulating identified ion transporters in guard cells, and the details of the underlying signalling pathways start to emerge. ABA actions in other cell types involve modifications of gene expression. The promoter analysis of ABA-responsive genes has revealed a diversity of cis-acting elements and a few associated trans-acting factors have been isolated. Finally, characterization of mutants defective in ABA responsiveness, and molecular cloning of the corresponding loci, has proven to be a powerful approach to dissect the molecular nature of ABA signalling cascades.
