DARMORV10_C09P30340.1 — Brassica napus

Summary

BnRGA (RGA) on chromosome C09 of oilseed rape encodes a DELLA-domain GRAS family transcriptional co-regulator. The product is annotated with gibberellin binding, phytochrome binding, blue light photoreceptor activity, and cis-regulatory DNA binding, and is linked to SMT3 activating enzyme, SUMO-specific endopeptidase, and phosphatase activities. In B. napus, the gene is associated with regulation of gibberellic acid signalling, shade avoidance, trichome morphogenesis, inflorescence meristem growth, floral organ morphogenesis, and singlet oxygen-mediated programmed cell death. It is linked to numerous agronomic traits including harvest index, leaf area, flower number, fruit set, seed storage protein content, total soluble sugar and flavonoid content, copper sensitivity, nematode damage response, and root width. Related genes in other species are associated with drought tolerance, seed number, fruit length, parthenocarpy, and clubroot resistance.
