TL;DR: The evidence for the role of GA in these processes, and the regulation of the GA signalling pathway on exposure to abiotic stress are reviewed, are reviewed.

TL;DR: Yeast two-hybrid and in vitro pull-down assays confirmed that GA enhances the interaction between GID1 and DELLA proteins, and showed that the GA-GID1 complex promotes the interactionbetween RGA and the F-box protein SLY1, a component of the SCFSLY1 E3 ubiquitin ligase that targets the DeLLA protein for degradation.

TL;DR: The present review discusses the current state of knowledge on GA metabolism with particular emphasis on regulation, including the complex mechanisms for the maintenance of GA homoeostasis.

TL;DR: This report demonstrated that SLY1 interacts directly with RGA and GA INSENSITIVE (GAI, a closely related DELLA protein) via their C-terminal GRAS domain, and identified a novel gain-of-function sly1-d mutation that increased GA signaling by reducing the levels of the DEllA protein in plants.

TL;DR: This study reveals that DELLA proteins play two important roles in GA signaling: (1) they help establish GA homeostasis by direct feedback regulation on the expression of GA biosynthetic and GA receptor genes, and (2) they promote theexpression of downstream negative components that are putative transcription factors/regulators or ubiquitin E2/E3 enzymes.
