HY4 (GLYMA_04G101500V4) — Glycine max

Summary

GmHY4 (GLYMA_04G101500V4) encodes a protein with cryptochrome and photolyase domains, and is annotated with blue-light photoreceptor activity, DNA photolyase activity, and transcription coactivator activity. In soybean, this gene is associated with the regulation of post-embryonic development, circadian clock photoentrainment, gibberellin-mediated signaling, and raffinose family oligosaccharide biosynthesis. It is linked to numerous agronomic traits including grain yield, leaf angle, leaf area, seed set percent, photoperiod sensitivity, photosynthetic ability, plant male sterility, and responses to light quality, UV light, glyphosate, aphids, and viral disease. The gene is also connected to phenotypes such as pod elongation, growth regulation, pathogen resistance, and delayed flowering. Related genes in other species are linked to blue light reception, floral transition, hypocotyl growth inhibition, and resistance to Pseudomonas syringae.
