CARSR12 — Cucumis melo

Summary

MELO3C015470.2 (CARSR12) on melon chromosome 3 encodes a beta-galactosidase (EC 3.2.1.23) with a glycoside hydrolase 35 domain and galactose-binding lectin domain. The enzyme is associated with galactose breakdown, carbohydrate metabolism, sucrose metabolism, and fruit development. It has been linked to plant-type cell wall modification, suberin biosynthesis, phloem transport, leaf vascular tissue pattern formation, auxin and brassinosteroid signaling, and protein phosphorylation. The protein localizes to the apoplast, cell wall, vacuole, plasmodesma, and secretory vesicle. Associations include leaf vein morphology, respiration rate, fruit color, fruit softening, fruit firmness, fruit maturity, hypocotyl elongation, trichome development, cell differentiation, pollen maturation, xyloglucan structure, cell wall extension, vascular development, and premature senescence. Studies of related genes in other species link it to fruit ripening, cell wall galactose content, fruit cracking, cell wall modification, and cell elongation.
