GLYMA_06G196200V4 — Glycine max

Summary

GmPRR1 (GLYMA_06G196200V4) encodes a phosphorelay response regulator with DNA-binding transcription factor activity, containing ARR-like and CCT domains. It is associated with circadian rhythm regulation, including photoentrainment and rhythmic processes, as well as energy homeostasis, thermomorphogenesis, and auxin biosynthesis. The gene has been linked to photoperiod sensitivity, seed protein content, starch grain synthesis, and responses to flooding, drought stress, and nematode damage. Additional associations include stomatal aperture, cuticle properties, abscisic acid accumulation, and leaf area. Related genes in other species connect the family to circadian clock function, flowering time, and hypocotyl elongation under light. GmPRR1 localizes to the nucleus and cytosol and is associated with plastid organization and regulation of photosynthesis.
