IRX9 — Asparagus officinalis
Summary
A4U43_C07F3870 (AoIRX9) on asparagus chromosome 7 encodes a protein with a Glyco_trans_43 domain and nucleotide-diphosphosugar transferase domain, possessing xylosyltransferase, galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase, and transglycosidase activities. The gene is associated with glucuronoxylan and xylan biosynthesis and anabolism, secondary cell wall biogenesis, and cell wall organization, and its product localizes to the Golgi membrane and Golgi complex. AoIRX9 is associated with xylan chain elongation, glucuronic acid patterning, xylan acetylation, secondary cell wall thickening, and xylem development. Related genes in other species link the family to decreased xylan abundance in cell walls and reduced stem strength with thinner fiber and vessel walls.
