LEN1 — Pisum sativum

Summary

PSAT6G016920 (symbol LEN1, also known as PsCPN60B) encodes the RuBisCO large subunit-binding protein subunit beta, chloroplastic, a chaperonin of the Cpn60/GroEL family with ATP-dependent protein folding chaperone and rubisco activator activities. In garden pea (Pisum sativum), this gene is associated with chloroplast organization, protein folding and import, seed germination, embryo development, and responses to light intensity, cold, and jasmonic acid. It is linked to photosynthetic rate, thermotolerance of photosynthesis, seed yield and weight, biomass, leaf senescence, plastid development, cotyledon morphology, disease tolerance, and heat tolerance. The product localizes to the chloroplast thylakoid membrane, envelope, stromule, and other compartments. Studies of related genes in other species link the family to photosynthesis temperature response, Rubisco activation, heat stress tolerance, and growth.
