GLU2 — Sorghum bicolor

Summary

SORBI_3008G079800 (GLU2) on sorghum chromosome 8 encodes a 4-hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl glucoside beta-D-glucosidase, a member of the glycoside hydrolase family 1. The enzyme exhibits beta-glucosidase, DIMBOA glucoside beta-D-glucosidase, xylanase, galactosidase, and mannosidase activities. This gene is associated with detoxification, defense response, secondary metabolism, carbohydrate metabolism, cytokinin signaling, and the TCA cycle. The encoded protein localizes to the chloroplast stroma and extracellular space. GLU2 is associated with drought tolerance. Related genes in other species connect the family to beta-glucosidase activity (EC 3.2.1.21) and DIMBOA-glucoside beta-D-glucosidase activity (EC 3.2.1.188).
