UVR8 — Lactuca sativa

Summary

LsUVR8, encoded by the garden lettuce gene LSAT_V11C100007060 on chromosome 1, produces a protein with a regulator of chromosome condensation (RCC1) domain and is annotated for small GTPase binding. The gene is associated with photomorphogenesis, pigmentation, and response to stress, as well as with the upregulation of attachment of spindle microtubules to kinetochore and CPC localization to kinetochore. It has been linked to traits including shoot fresh weight, photosynthetic rate, stomatal resistance, and anthocyanin content, and to the phenotype of rosette diameter plasticity. The protein localizes to both the membrane and nucleus. Studies of related genes in other species connect the family to altered rosette growth under nitrogen limitation and to traits like plant height and seed maturation.
