PSAT2G072040 — Pisum sativum

Summary

PSAT2G072040 (HY4/CRY1) on pea chromosome 2LG1 encodes a cryptochrome with DNA photolyase activity, blue/red/far-red light photoreceptor activity, FAD binding, gibberellin binding, and transcription coactivator activity. It is associated with blue light reception, circadian clock photoentrainment, circadian regulation of gene expression, gibberellin-mediated signalling, floral organ morphogenesis, and detection of light. The gene is linked to numerous agronomic traits including grain yield, leaf area and angle, flower diameter, photoperiod sensitivity, seed set percent, photosynthetic ability, plant size, and responses to light quality, UV, glyphosate, aphids, and viral disease. It localises to the nucleus, cytoplasm, mitochondria, and plasmalemma, and is connected to SCF and Cul4-RING ubiquitin ligase complexes. Studies of related genes in other species link the family to hypocotyl growth, floral transition, blue light sensitivity, and resistance to Pseudomonas syringae.
