TCF1 — Lactuca sativa

Summary

LsTCF1 (also known as LsUVR8 or TCF1) on chromosome 2 of garden lettuce encodes a protein containing a regulator of chromosome condensation (RCC1) domain and a BLIP-II domain, with histone-binding and protein-binding molecular functions. The gene is associated with photomorphogenesis, pigmentation, and the regulation of lignin anabolism, as well as cellular responses to freezing and cold acclimation. It has been linked to traits including shoot fresh weight, photosynthetic rate, stomatal resistance, anthocyanin content, and freezing tolerance. The encoded protein localizes to both the cytoplasm and nucleus. Studies of related genes in other species connect the family to quantum yield, lignin content, seed maturation, low-temperature stress response, and plant height.
