BOP1 — Pisum sativum

Summary

PSAT3G077680 (BOP1) on garden pea chromosome 3LG5 encodes a protein with DNA binding, transcription cis-regulatory region binding, protein homodimerization, and hydrolase activities, containing BTB/POZ, ankyrin repeat, and NPR5/6 domains. It is associated with stipule, nectary, and flower morphogenesis, meristem determinacy, proximal/distal pattern formation, adaxial/abaxial polarity specification, leaf abscission, and organogenesis. The gene is associated with systemic acquired resistance and induced systemic resistance mediated by salicylic and jasmonic acid signaling pathways, as well as salicylic acid and cytokinin anabolism. It localizes to the nucleus, cytoplasm, plasma membrane, and nuclear body. Associations include leaf, flower, inflorescence, bract, root, and hypocotyl morphology traits, lignin biosynthesis, flowering time, disease tolerance, and plant architecture. Studies of related genes in other species link the family to shoot apical meristem maintenance, UV-B stress tolerance, and nematode resistance in soybean.
