Protein function

Encodes a negative regulator of gibberellin response that belongs to the DELLA family.

Phenotype

Overexpressor:
Specific overexpression of RGL1 in phloem companion cells (pSUC2) delays flowering under LD conditions. ( No data available under SD conditions.) [Galvü¾Œ¶”¼o et al., 2012]

Function:
Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. No effect of the BOI proteins on its stability. Probably acts by participating in large multiprotein complexes that repress transcription of GA-inducible genes. Has overlapping but distinct roles in GA signaling compared to RGA and GAI. Regulates the floral development. May also participate in seed germination and in ovule and anther development. Its activity is probably regulated by other phytohormones such as auxin and ethylene.
