CO — Lactuca sativa

Summary

LsCO (LSAT_V11C500247100) on lettuce chromosome 5 encodes a CONSTANS-like protein containing a CCT domain and zinc-finger B-box domains. The gene is associated with regulation of phytochrome signaling, photoperiodic flowering, and chlorophyll breakdown, as well as responses to light quality, including red and far-red light. It is linked to numerous traits such as photoperiod sensitivity, vegetative vigor, leaf morphology, seed protein content, and stress responses including water stress and nematode damage. Related genes in other species are associated with photoperiod-dependent flowering time, root architecture, stress tolerance, and tuberization.
