Definition and functional implications of gibberellin and abscisic acid cis-acting hormone response complexes.
The mechanisms by which cis-acting hormone response elements affect transcription is unclear. In this study, we demonstrated that a second "coupling element," identified as O2S, must be present to allow a single copy of either the gibberellin response element (GARE) or the abscisic acid response element (ABRE) to mediate their hormonal effects in the barley Amy32b alpha-amylase gene promoter. T...
متن کاملGenomics approach to abscisic acid- and gibberellin-responsive genes in rice.
We used an 8987-EST collection to construct a cDNA microarray system with various genomics information (full-length cDNA, expression profile, high accuracy genome sequence, phenotype, genetic map, and physical map) in rice. This array was used as a probe to hybridize target RNAs prepared from normally grown callus of rice and from callus treated for 6 hr or 3 days with the hormones abscisic aci...
متن کاملGibberellin and abscisic acid signalling in aleurone.
The plant hormones gibberellin and abscisic acid regulate gene expression, secretion and cell death in aleurone. The emerging picture is of gibberellin perception at the plasma membrane whereas abscisic acid acts at both the plasma membrane and in the cytoplasm - although gibberellin and abscisic acid receptors have yet to be identified. A range of downstream-signalling components and events ha...
متن کاملTwo cis-acting elements necessary and sufficient for gibberellin-upregulated proteinase expression in rice seeds.
In germinating rice seeds, a cysteine proteinase (REP-1), synthesized in aleurone-layer cells, is a key enzyme in the degradation of the major storage protein, glutelin. The expression of the gene for REP-1 (Rep1) is induced by gibberellins (GAs) and repressed by abscisic acid (ABA). To identify GA-responsive elements in the Rep1 promoter, we developed a transient expression system in rice aleu...
متن کاملPLACE: a database of plant cis-acting regulatory DNA elements
PLACE (http://www.dna.affrc.go.jp/htdocs/PLACE/) is a database of motifs found in plant cis -acting regulatory DNA elements, all from previously published reports. It covers vascular plants only. In addition to the motifs originally reported, their variations in other genes or in other plant species reported later are also compiled. The PLACE database also contains a brief description of each m...
