Xyl1 — Zea mays

Summary

ZM00001EB214880 (Xyl1) on maize chromosome 5 encodes a glycoside hydrolase family 3 protein with xylan 1,4-beta-xylosidase, alpha-L-arabinofuranosidase and beta-glucosidase activities. The gene is associated with breakdown of xylan, arabinan, beta-glucan and glucan, as well as cell wall biogenesis, pollen adhesion, phloem loading, protein storage, fermentation, autolysis, amino acid efflux, bone mineralization, digestion, cell development, homologous recombination, mitosis, meiosis and cellular localization. Its product localizes to the apoplast. Xyl1 has been linked to grain weight, grain yield, starch content, starch digestibility, protein content, soluble protein content and ash content. Studies of related genes in other species place the family within EC 3.2.1.37 and EC 3.2.1.55.
