CYCLOPS — Pisum sativum

Summary

PSAT2G142200, designated CYCLOPS on garden pea (Pisum sativum) chromosome 2LG1, encodes a protein with sequence-specific DNA binding, protein homodimerization activity, and DNA binding transcription factor activity. The product localizes to the nucleus. CYCLOPS is associated with nodulation, nitrogen fixation, arbuscular mycorrhizae formation, cytokinin signaling, morphogenesis, regulation of DNA-templated transcription, transposition, and localization. Related genes in other species link the gene family to root nodule symbiosis and mycorrhizal associations, though this specific mechanism is not established in pea. The gene is related to CYCLOPS orthologs in soybean (Glycine max) and common bean (Phaseolus vulgaris), underscoring its conserved role in legume symbiotic interactions.
