Gibberellin signal transduction.
Recent studies using biochemical and genetic approaches have identified a number of components, including several negative regulators, of the gibberellin (GA) signal transduction pathway in higher plants. The basal state of GA signaling is likely to be repressive, and the GA signal seems to activate the pathway by de-repression to allow GA-stimulated growth and development.
متن کاملGenetic Analysis of Gibberellin Signal Transduction.
In recent years exciting progress has been made in understanding how endogenous plant hormones control plant development. One of the fundamental questions in this area of research is the mechanism by which the presente of a plant hormone molecule (the signal) leads to a change in plant development (the transduction pathway). This Update will discuss progress in the genetic analysis of signal tr...

متن کاملGibberellin biosynthesis and signal transduction is essential for internode elongation in deepwater rice
Under flooded conditions, the leaves and internodes of deepwater rice can elongate above the water surface to capture oxygen and prevent drowning. Our previous studies showed that three major quantitative trait loci (QTL) regulate deepwater-dependent internode elongation in deepwater rice. In this study, we investigated the age-dependent internode elongation in deepwater rice. We also investiga...
متن کاملRice dwarf mutant d1, which is defective in the alpha subunit of the heterotrimeric G protein, affects gibberellin signal transduction.
Previously, we reported that the rice dwarf mutant, d1, is defective in the alpha subunit of the heterotrimeric G protein (Galpha). In the present study, gibberellin (GA) signaling in d1 and the role of the Galpha protein in the GA-signaling pathway were investigated. Compared with the wild type, GA induction of alpha-amylase activity in aleurone cells of d1 was greatly reduced. Relative to the...
