LEN1 — Camelina sativa

Summary

CsLEN1 (CSA03G062070) on Camelina sativa chromosome 3 encodes a chaperonin of the Cpn60/GroEL family with rubisco activator and ATP-dependent protein folding chaperone activity. The gene is associated with protein folding, chloroplast organization, heat acclimation, response to cold and jasmonic acid, systemic acquired resistance, inflorescence development, and embryo development ending in seed dormancy. It localizes to the thylakoid, chloroplast envelope, stromule, and apoplast. CsLEN1 is associated with photosynthetic rate, seed yield and weight, leaf temperature, selenium and sulfur content, heat tolerance, biomass, oil content, thermotolerance of photosynthesis, leaf senescence, disease tolerance, plastid development, cotyledon morphology, and circadian clock-regulated gene expression. Studies of related genes in other species link the family to photosynthesis temperature response, Rubisco activation, heat stress tolerance, and growth.
