LEN1 — Camelina sativa

Summary

CSA11G089900 (CsLEN1) on Camelina sativa chromosome 11 encodes a chaperonin of the Cpn60/GroEL family with rubisco activator and ATP-dependent protein folding chaperone activity. The gene is associated with chloroplast organization, thylakoid and chloroplast envelope localization, and responses to light, cold, heat, and jasmonic acid. It is linked to systemic acquired resistance, inflorescence development, embryo development, and brassinosteroid-mediated signaling. Traits associated with CsLEN1 include photosynthetic rate, seed yield and weight, leaf temperature, selenium and sulfur content, nitrate uptake, heat tolerance, biomass, oil content, and disease tolerance. Phenotypes connected to the gene include thermotolerance of photosynthesis, leaf senescence, circadian clock-regulated gene expression, plastid development, and cell death with lesion formation. Studies of related genes in other species link the family to Rubisco activation, photosynthesis temperature response, heat stress tolerance, and peroxisomal protein import.
