CPS — Phaseolus vulgaris

Summary

PHAVU_001G152100 (PvCPS) on chromosome 1 of French bean encodes a terpene synthase with ent-copalyl diphosphate synthase, kolavenyl diphosphate synthase, and copal-8-ol diphosphate synthase activities. The gene is associated with gibberellin signaling, diterpenoid and terpenoid biosynthesis, defense response, and 2-oxoglutarate transport. It has been connected to photosynthetic rate, seed germination, plant height, flowering time, trichome formation, apical hook formation, root colonization, floral organ size, and carotenoid and chlorophyll biosynthesis. Associations also include dwarfism, plant growth and development, and photooxidative stress resistance. Studies of related genes in other species link the family to male fertility, stem elongation, and GA-responsive dwarfism.
