LSAT_V11C200082020 — Lactuca sativa

Summary

LsCO (CO) on chromosome 2 of garden lettuce encodes a CONSTANS-like protein with a CCT domain and Znf_B-box, and is annotated with diverse molecular functions including OGTase, peptide-O-fucosyltransferase, and histone methylase activities. The gene is associated with regulation of phytochrome signaling, photoperiodic flowering, chlorophyll breakdown, and circadian clock entrainment. It has been linked to numerous traits such as photoperiod sensitivity, inflorescence branch arrangement, seed protein content, leaf angle, trichome density, and responses to water stress, nitrogen, and UV light. Studies of related genes in other species connect it to photoperiod-dependent flowering time, heat stress tolerance, root architecture, and disease resistance.
