CPS — Pisum sativum

Summary

PSAT3G199080 (CPS, PsCPS) on garden pea chromosome 3LG5 encodes a terpene synthase with ent-copalyl diphosphate synthase, kolavenyl diphosphate synthase and copal-8-ol diphosphate synthase activities, along with isomerase activity and magnesium binding. The gene is associated with gibberellin signaling, diterpenoid and terpenoid anabolism, miltiradiene biosynthesis, and the ent-kaurene and momilactone biosynthesis pathways. It has been linked to regulation of seed and fruit development, seed maturation, cell growth, morphogenesis, chlorophyll biosynthesis, syngamy, RNA splicing, protein breakdown, and homeostasis. Associations with agronomic traits include fruit size, stem elongation, photosynthetic rate, protein content, plant height, flowering time, seed germination, trichome formation, root colonization, and photooxidative stress resistance. Studies of related genes in other species link the family to dwarfism, male sterility, and gibberellin-responsive growth.
