LE — Cucumis sativus

Summary

CsLE (CSA_7G434970) on cucumber chromosome 7 encodes a gibberellin 3-beta-dioxygenase (EC 1.14.11.15), a 2-oxoglutarate-dependent dioxygenase of the IPNS-like superfamily. The gene is associated with gibberellin biosynthesis and 3beta-hydroxylation, and has been linked to plant height, hypocotyl growth, fruit growth, seed dormancy, germination, flowering time, stamen and petal development, and sex expression. Associations also include vegetative growth, primary root growth, trichome formation, and traits such as harvest index, chlorophyll content, and hydrogen peroxide content. The gene product is annotated to multiple metabolic processes including hormone, carotenoid, auxin, cytokinin, jasmonic acid, ethylene, and lignin anabolism, as well as responses to red or far-red light and abscission. Studies of related genes in other species link the family to seed germination, starch degradation, seed coat formation, and tuberization.
