RBCS — Pisum sativum

Summary

PsRBCS (PSAT3G205160) on chromosome 3LG5 encodes a protein with RuBisCO_ssu domains and annotated RuBisCO activity, as well as histone acetyltransferase activity, double-stranded methylated DNA binding, ubiquitin ligase binding, chaperone protein binding, salicylic acid binding, acyltransferase activity, histone binding, copper binding, calmodulin binding, and transmembrane receptor protein serine/threonine kinase activity. The gene is associated with RuBisCO assembly, the reductive pentose-phosphate cycle, photorespiration, and plastid translation. It is linked to photosynthetic rate, CO2 assimilation, chloroplast development and function, leaf vein morphology, and responses to high and low temperature, oxidative stress, boron, zinc, and herbicide sensitivity. Additional associations include flowering time, plant height, root and meristem development, gametogenesis, and disease tolerance. The product localises to the chloroplast thylakoid membrane and lumen, chloroplast envelope, and also to the proteasome, cytosolic ribosome, and stress granules. Studies of related genes in other species link the family to photosynthetic capacity, photoinhibition, drought tolerance, and immune response.
