The Arabidopsis gai mutant allele confers a reduction in gibberellin (GA) responsiveness.
Here we report the molecular cloning of GAI and a closely related gene GRS. The predicted …

RGA and GAI are homologous genes that encode putative transcriptional regulators that
repress gibberellin (GA) signaling in Arabidopsis. Previously we showed that the green …

Gibberellins (GAs) are a major class of plant hormones that control many developmental
processes, including seed development and germination, flower and fruit development, and …

We have identified a new locus involved in gibberellin (GA) signal transduction by screening
for suppressors of the Arabidopsis thaliana GA biosynthetic mutant ga1-3. The locus is …

Bioactive gibberellins (GAs) are essential endogenous regulators of plant growth. GA
signaling is mediated via GAI, a nuclear member of the GRAS family of plant transcription …

Active gibberellins (GAs) are endogenous factors that regulate plant growth and
development in a dose-dependent fashion. Mutant plants that are GA deficient, or exhibit …

In Arabidopsis, the DELLA subfamily of GRAS regulatory genes consists of GAI, RGA, RGA-
LIKE1 (RGL1), RGL2, and RGL3. GAI and RGA are known to be negative regulators of …

The growth of Arabidopsis thaliana is quantitatively regulated by the phytohormone
gibberellin (GA) via two closely related nuclear GA-signaling components, GAI and RGA …

RGA and GAI are negative regulators of the gibberellin (GA) signal transduction pathway in
Arabidopsis thaliana. These genes may have partially redundant functions because they are …

DELLA proteins, consisting of GA INSENSITIVE, REPRESSOR OF GA1-3, RGA-LIKE1
(RGL1), RGL2, and RGL3, are central repressors of gibberellin (GA) responses, but their …
