DARMORV10_C07P32180.1 — Brassica napus

Summary

BnRGA (RGA, DARMORV10_C07P32180.1) on chromosome C07 of oilseed rape encodes a DELLA protein, a member of the GRAS transcription factor family, with domains including DELLA_N and GRAS. The gene product is associated with transcriptional co-regulation, gibberellin binding, phytochrome binding, and blue light photoreceptor activity, as well as SMT3 activating enzyme, SUMO-specific endopeptidase, and phosphatase activities. It is linked to regulation of gibberellic acid-mediated signalling, shade avoidance, trichome morphogenesis, floral organ morphogenesis, and inflorescence meristem growth. Associations include traits such as harvest index, leaf area, flower number, fruit set, root width, copper sensitivity, phenolic compound content, and total soluble sugar content. The gene is also associated with abiotic stress response, increased biomass, reduced bacterial susceptibility, and early flowering. Related genes in other species link the family to drought tolerance, embryo viability, and seed number.
