LEN1 — Pisum sativum

Summary

PsLEN1 (PSAT1G001680) on pea chromosome 1LG6 encodes a CPN-60 beta chaperonin with rubisco activator and ATP-dependent protein folding chaperone activity. It is associated with chloroplast organization, protein folding and refolding, protein import and targeting, seed germination, embryo development, systemic acquired resistance, and responses to light intensity, jasmonic acid, cold, and brassinosteroid signalling. The gene is linked to seed yield, biomass, seed weight, photosynthetic rate, thermotolerance of photosynthesis, heat tolerance, leaf senescence, plastid development, cotyledon morphology, root morphology, nitrate uptake, and disease tolerance. Studies of related genes in other species connect the family to Rubisco activation, photosynthesis temperature response, heat stress tolerance, and leaf lesion formation with systemic acquired resistance.
