Target Background

Function
Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. Probably acts by participating in large multiprotein complexes that repress transcription of GA-inducible genes. Positively regulates XERICO expression in seeds. Upon GA application, it is degraded by the proteasome, allowing the GA signaling pathway. Compared to other DELLA proteins, it is the most sensitive to GA application. No effect of the BOI proteins on its stability. Its activity is probably regulated by other phytohormones such as auxin and ethylene, attenuation of auxin transport delaying its GA-induced degradation. Involved in the regulation of seed dormancy and germination, including glucose-induced delay of seed germination.
Gene References into Functions
  1. RGA negatively regulate dark-induced senescence and chlorophyll degradation.RGA physically interacts with WRKY6. PMID: 29574486
  2. The six conserved Ser/Thr sites are important for the different bioactivities of the RGA protein that regulate the gibberellin (GA) response, and also for RGA stability via the mimicking of phosphorylation/de-phosphorylation. PMID: 25056926
  3. RGA and GAI play distinct roles in seed germination. PMID: 25064446
  4. DELLA activity is essential for Arabidopsis pollen development. PMID: 24400898
  5. Data indicate that BZR1 interacts in vitro and in vivo with REPRESSOR OF ga1-3 (RGA), a member of the DELLA family of transcriptional regulators that inhibits the gibberellins (GAs) signaling pathway. PMID: 23033541
  6. RGA represses flowering in leaves through FT and miR172 under long-day conditions, and represses flowering at the shoot apex through MADS box genes. PMID: 22942378
  7. Studies indicate that GRAS proteins are named after the first three members: GIBBERELLIC ACID INSENSITIVE (GAI), REPRESSOR of GAI (RGA) and SCARECROW (SCR), and they have diverse roles in plant development and signal transduction. PMID: 21732203
  8. SPT acts in an analogous manner to the gibberellin-dependent DELLAs, REPRESSOR OF GA1-3 and GIBBERELLIC ACID INSENSITIVE, which restrain cotyledon expansion alongside SPT. PMID: 21478445
  9. We show that repression of germination by far-red light involves stabilized DELLA factors GAI, RGA and RGL2 that stimulate endogenous abscisic acid synthesis which, in turn, blocks germination through the transcription factor ABI3. PMID: 19556968
  10. SLEEPY1 interacts directly with RGA and GA INSENSITIVE (GAI, a closely related DELLA protein) via their C-terminal GRAS domain PMID: 15155881
  11. SLY1 (the wild-type form) and sly1gar2-1 both confer substrate specificity on this complex via specific binding to the DELLA proteins, GAI and RGA PMID: 15161962
  12. We show that ga1-3 seeds lacking RGA, RGL1 and RGL2 or GAI, RGL1 and RGL2, confer GA-independent germination in the light but not in the darkness whilst ga1-3 seeds lacking GAI, RGA and RGL2 germinate both in the light and darkness. PMID: 16034591
  13. DELLA abundance is regulated during growth responses to neighbours in dense Arabidopsis stands. This occurs in a red:far red ratio-dependent manner in petioles, depends on gibberellin, and matches the induction kinetics of petiole elongation. PMID: 17488236
  14. Data show that cold/CBF1 enhances the accumulation of a green fluorescent protein (GFP)-tagged DELLA protein (GFP-RGA) by reducing GA content through stimulating expression of GA-inactivating GA 2-oxidase genes. PMID: 18757556
  15. Data documented that Lys-29 of ubiquitin is the major site for ubiquitin chain formation to mediate DELLA protein degradation that also required protein Ser/Thr dephosphorylation activity. The LZ domain is essential for both their stability and activity. PMID: 19717618
