BGLU19 — Brassica napus

Summary

BnBGLU19 (BGLU19) on chromosome A01 of oilseed rape (Brassica napus) encodes a glycosyl hydrolase family 1 protein with beta-glucosidase, beta-galactosidase, beta-D-fucosidase, glucan exo-1,3-beta-glucosidase, beta-gentiobiose beta-glucosidase, raucaffricine beta-glucosidase, vomilenine glucosyltransferase, and beta-L-arabinosidase activities, and also transcription coactivator and protein binding activities. The gene is associated with numerous biological processes including pentose breakdown, quinone and zeatin anabolism, nitrogen homeostasis, secondary metabolite biosynthesis, and glutathione, proline, methionine, and glutamate metabolism. It is linked to traits such as plant fresh weight, root volume, sodium uptake and content, seed weight and viability, water use efficiency, anthocyanin content, leaf and floral organ development, heterosis, and cytoplasmic male sterility. The protein localises to the extracellular region, cytosol, and nucleus. Related genes in other species link the family to salt tolerance, seed-specific expression, organ size, iron uptake, seed size, leaf cell proliferation, and anthocyanin biosynthesis.
