BGLU18 — Zea mays

Summary

ZM00001EB426520 (BGLU18) on maize chromosome 10 encodes a glycoside hydrolase family 1 protein with beta-glucosidase, coniferin beta-glucosidase, beta-mannosidase, cellobiose glucosidase, beta-L-arabinosidase, beta-gentiobiose beta-glucosidase, glucan exo-1,3-beta-glucosidase, beta-D-fucosidase, and beta-galactosidase activities. The gene is associated with glucose detection, response to external biotic stimulus, coniferin and glycoside metabolism, and delamination, and its product localises to the extracellular region. BGLU18 is linked to numerous agronomic traits including grain lysine and protein content, ear weight, biomass yield, harvest index, starch and amylopectin content, nitrogen and carbon content, specific leaf area, water use efficiency, and tolerance to salinity, heat, and cold. Studies of related genes in other species link this gene family to coniferin beta-glucosidase activity and broader glycoside metabolism.
