DARMORV10_A06P44280.1 — Brassica napus

Summary

BnRGA (RGA) on chromosome A06 of oilseed rape encodes a DELLA protein, a member of the GRAS transcription factor family, and is annotated with a wide range of molecular functions including gibberellin binding, phytochrome binding, blue light photoreceptor activity, transcriptional co-regulator activity, and protein serine/threonine phosphatase activity. The gene is associated with numerous biological processes such as regulation of gibberellic acid-mediated signalling, floral organ morphogenesis, inflorescence meristem growth, trichome spacing, and detection of light. It is linked to agronomically important traits including harvest index, leaf area, flower number, fruit set and quality, root width, seedling cotyledon size, total soluble sugar and flavonoid content, and responses to light quality, phosphorus, and nematode damage. Related genes in other species are associated with drought tolerance, seed number, fruit length, and heat stress tolerance.
