APSE — Brachypodium distachyon

Summary

BdAPSE (BRADI_3G29797V3) on Brachypodium distachyon chromosome 3 encodes a protein with alpha-galactosidase (melibiase) activity (EC 3.2.1.22), belonging to the glycoside hydrolase family 27. The enzyme is associated with raffinose and polysaccharide binding, and has been linked to galactomannan catabolism, arabinogalactan protein metabolism, and general carbohydrate and polysaccharide breakdown. It is also associated with endosperm development, seed germination, leaf morphogenesis, flower development, and response to fungi. The protein localises to the vacuole, apoplast, plant-type cell wall, and secretory vesicles. Additionally, BdAPSE is associated with salt response, leaf morphology, flowering time, and cell wall beta-l-arabinopyranose content. Studies of related genes in other species link the family to drought and cold tolerance, root and leaf morphology traits, flowering time, and agronomic traits such as sugar and protein content.
