DARMORV10_A09P23510.1 — Brassica napus

Summary

BnRGA (RGA) on chromosome A09 of oilseed rape encodes a DELLA-domain and GRAS-family transcriptional co-regulator. The product is associated with gibberellin and phytochrome binding, blue light photoreceptor activity, and is annotated as a protein tag and phosphatase. It is linked to regulation of gibberellic acid signalling, shade avoidance, systemic acquired resistance, nitrogen utilization, trichome morphogenesis, inflorescence meristem growth, floral organ morphogenesis, and singlet oxygen-mediated programmed cell death. Associations with agronomic traits include harvest index, flower number, fruit set, fruit quality, leaf area, root width, seedling cotyledon size, inflorescence length, total soluble sugar and flavonoid content, iron content, copper sensitivity, and nematode damage response. Studies of related genes in other species connect the family to drought tolerance, heat tolerance, clubroot resistance, seed number, fruit length, and root epidermal patterning.
