LEN1 — Camelina sativa

Summary

CsLEN1 (CSA17G095320) in Camelina sativa 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 localization, and protein folding processes including refolding and stabilization. CsLEN1 is associated with photosynthetic rate, thermotolerance of photosynthesis, photosynthetic efficiency, and CO2 fixation, as well as seed yield, seed weight, oil content, and biomass. Additional associations include responses to heat, cold, light, jasmonic acid, and brassinosteroid signaling, along with systemic acquired resistance, inflorescence development, and embryo development ending in seed dormancy. The gene is also linked to leaf senescence, disease tolerance, and plastid development traits. Studies of related genes in other species connect the family to rubisco activation, photosynthesis temperature response, and heat stress tolerance.
