CARSR12 — Capsicum annuum

Summary

T459_30550 (CARSR12) on pepper chromosome 12 encodes a beta-galactosidase (EC 3.2.1.23) with a galactose-binding lectin domain and glycoside hydrolase family 35 catalytic domain, and is also annotated with transmembrane receptor protein serine/threonine kinase activity and protein binding. The gene is associated with galactose breakdown, carbohydrate metabolism, auxin and brassinosteroid signalling, suberin biosynthesis, cell wall modification, phloem transport, leaf vascular tissue pattern formation, oxidative phosphorylation, demethylation, and NO storage. It localises to the secretory vesicle, vacuole, apoplast, cell wall, plasmodesma, plasma membrane, cytosol, and nucleus. Associations include polysaccharide content, leaf vein morphology, respiration rate, seed longevity, fruit colour, hypocotyl elongation, trichome development, fruit firmness, cell wall extension, vascular development, and premature senescence. Studies of related genes in other species link the family to fruit ripening, softening, cracking, and cell wall galactose content.
