CARSR12 — Asparagus officinalis

Summary

A4U43_C01F23190 (CARSR12) on asparagus chromosome 1 encodes a beta-galactosidase (EC 3.2.1.23) with a galactose-binding lectin domain and glycoside hydrolase 35 family domains, and is associated with beta-galactosidase activity, sugar binding, and transmembrane receptor protein serine/threonine kinase activity. The gene is associated with galactose breakdown, suberin biosynthesis, plant-type cell wall modification, phloem transport, leaf vascular tissue pattern formation, auxin signaling, and brassinosteroid-mediated signaling. It localizes to the secretory vesicle, vacuole, apoplast, plant-type cell wall, plasmodesma, plasma membrane, and nucleus. Associations include leaf vein morphology, respiration rate, fruit color, hypocotyl elongation, trichome development, cell differentiation, pollen maturation, fruit firmness, cell wall extension, vascular development, and premature senescence. Studies of related genes in other species link the family to fruit ripening, softening, and cell wall modification.
