CPS — Arabidopsis thaliana

Summary

AT4G02780 (CPS, also known as GA1) encodes ent-copalyl diphosphate synthase, an enzyme with terpene synthase activity that catalyses the conversion of geranylgeranyl diphosphate to syn-copalyl diphosphate in the ent-kaurene and gibberellin biosynthesis pathways. This gene is associated with numerous developmental and reproductive processes, including flower formation, stamen development, leaf formation, post-embryonic root development, meristem maintenance, and shade avoidance. It is linked to traits such as seed germination, male fertility, stamen and petal length, floral organ size, stem elongation, plant height, flowering time, seed dormancy and viability, leaf number, petiole length, trichome morphology, and root mass density. The gene product localises to the chloroplast and is also associated with carotenoid and glucosinolate anabolism, vernalisation response, and hypersensitivity. Related genes in other species link the family to fruit development, fruit set, and sex expression.
