CPS — Lactuca sativa

Summary

LsCPS (CPS) on chromosome 9 of garden lettuce encodes a terpene synthase with kolavenyl diphosphate synthase, ent-copalyl diphosphate synthase, copal-8-ol diphosphate synthase, isomerase and terpene synthase activities, and binds magnesium. It belongs to the terpene cyclase and terpene synthase domain families. The gene is associated with geranylgeranyl diphosphate metabolism, miltiradiene and diterpenoid anabolism, hormone metabolism, gibberellin signaling, and defense response. It has been linked to plant height, dwarfism, flowering time, seed dormancy, trichome formation, apical hook formation, root colonization, parthenocarpic fruit-set, and resistance to photooxidative stress, as well as carotenoid and chlorophyll biosynthesis. Studies of related genes in other species connect the family to additional traits including fruit development, male fertility, stem elongation, and drought tolerance.
