DARMORV10_A02P00920.1 — Brassica napus

Summary

BnHY5 (DARMORV10_A02P00920.1) on chromosome A02 of oilseed rape encodes a bZIP transcription factor of the Hac1/HY5 family with DNA-binding transcription activator activity, phytochrome binding, and photoreceptor activities. This gene is associated with the regulation of phytochrome signaling, upregulation of photosynthesis, chlorophyll metabolism, cellular water homeostasis, and upregulation of lateral root development. It has been linked to numerous agronomic traits including grain yield, seed coat hardness and color, leaf area and angle, fruit quality, total soluble sugar content, osmotic adjustment capacity, vegetative vigor, and responses to UV, far-red, and blue light. Associations also include cold tolerance, viral disease response, brassinosteroid and gibberellic acid content, root system morphology, and plastid development. The gene localizes to the nucleus, cytosol, plasmodesma, and mitochondria, and is connected to ubiquitin ligase complexes.
