LEN1 — Camelina sativa

Summary

CsLEN1 (CSA02G059770) on Camelina sativa chromosome 2 encodes a chaperonin of the Cpn60/GroEL family with rubisco activator, ATP-dependent protein folding chaperone and ATP hydrolase activities. The gene is associated with protein folding, refolding and stabilization, chloroplast organization, heat acclimation, systemic acquired resistance, inflorescence development, embryo development, and responses to jasmonic acid, cold and light stimulus. It localizes to the thylakoid, chloroplast envelope, stromule, apoplast and plant-type cell wall. CsLEN1 is linked to photosynthetic rate, thermotolerance of photosynthesis, seed yield, seed weight, oil content, biomass, leaf senescence, disease tolerance, heat tolerance, plastid development, cotyledon morphology, root morphology, nitrate uptake, and selenium and sulfur content. Studies of related genes in other species connect the family to Rubisco activation, photosynthesis temperature response, heat stress tolerance, and systemic acquired resistance.
