GLYMA_09G035500V4 — Glycine max

Summary

GmHY3 (GLYMA_09G035500V4) on soybean chromosome 9 encodes a protein with phytochrome A-E, GAF, PAS, and histidine kinase domains, and is associated with photoreceptor activity and tetrapyrrole binding. This gene is associated with regulation of plant organ formation, phytochrome chromophore biosynthesis, and positive regulation of phytochrome signaling. It has been linked to numerous agronomic traits including grain yield, plant dry weight, leaf area, stem diameter, panicle number, flower diameter, seedling cotyledon size, inflorescence length, vegetative vigor, relative growth rate, and responses to light quality, far-red light, and submergence. Associations also include chlorophyll content and ratio, starch synthesis and content, carbon assimilation, and stress responses such as copper and glyphosate sensitivity. Studies of related genes in other species link the family to shade avoidance, floral transition, drought tolerance, and thermotolerance.
