LEN1 — Camelina sativa

Summary

CsLEN1 (CSA15G017590) in Camelina sativa encodes a chaperonin of the Cpn60/GroEL family with rubisco activator, ATP-dependent protein folding chaperone and ATP hydrolase activities. It is associated with protein folding, stabilization and refolding, chloroplast organization, heat acclimation, response to cold, jasmonic acid and light stimulus, systemic acquired resistance, inflorescence and embryo development, and brassinosteroid-mediated signalling. The gene is linked to photosynthetic rate and efficiency, thermotolerance of photosynthesis, seed yield and weight, oil content, biomass, leaf senescence, plastid and cotyledon development, root morphology, nitrate uptake, and disease tolerance. It localizes to the thylakoid, chloroplast envelope and membrane, stromule, apoplast, and plant-type cell wall. Studies of related genes in other species connect the family to Rubisco activation, photosynthesis temperature response, heat stress tolerance, and peroxisomal protein import.
