UVR8 — Lactuca sativa

Summary

LsUVR8, encoded by the garden lettuce gene LSAT_V11C500252680 on chromosome 5, is a protein containing BRX_N, FYVE zinc finger, and RCC1/BLIP-II domains, and is annotated for phosphoinositide and metal binding. In lettuce, this gene is associated with photomorphogenesis, pigmentation, signal transduction, and response to stress, and its product localises to the cytoplasm and Golgi complex. It has been linked to shoot fresh weight, photosynthetic rate, stomatal resistance, and anthocyanin content. Studies of related genes in other species connect the UVR8/PRAF6 family to plant height, seed maturation, and quantum yield, though these associations are not yet established in lettuce.
