LE — Lactuca sativa

Summary

LsLE (LSAT_V11C100014390) on lettuce chromosome 1 encodes a gibberellin 3-beta-dioxygenase, a member of the 2-oxoglutarate-dependent dioxygenase family. This gene is associated with gibberellin biosynthesis and signaling, and with responses to red and far-red light. It has been linked to numerous growth and developmental traits, including plant height, leaf size, root growth, hypocotyl elongation, flowering time, seed dormancy and germination, stamen and petal development, fruit growth, and trichome formation. The gene is also associated with vegetative growth, starch degradation, seed coat development, and seed tolerance to deterioration. Studies of related genes in other species further link the family to gibberellin metabolism, tuberization, somatic embryogenesis, and traits such as harvest index, stem length, and chlorophyll content.
