CPS — Nicotiana attenuata

Summary

A4A49_18119 (CPS2) on chromosome 2 of coyote tobacco encodes a terpene synthase-like protein with copalyl diphosphate synthase, ent-copalyl diphosphate synthase, and peregrinol diphosphate synthase activities. The gene is associated with diterpenoid and gibberellin metabolism, terpenoid biosynthesis and breakdown, defense response, innate immunity, cell death, and morphogenesis. It is linked to plant height, stem elongation, flowering time, dwarfism, trichome formation, apical hook formation, root colonization, germination rate, protein content, and parthenocarpic fruit-set. Studies of related genes in other species link the family to seed germination, stamen and petal length, male fertility, and GA-deficient dwarfism with male sterility, while work in tomato connects it to fruit development.
