The irregular xylem9 mutant is deficient in xylan xylosyltransferase activity.

Plant & cell physiology - 1 Nov 2007

Abstract excerpt

Xylan is the second most abundant polysaccharide in dicot wood, and thus elucidation of the xylan biosynthetic pathway is required to understand the mechanisms controlling wood formation. Genetic and chemical studies in Arabidopsis have implicated three genes, FRAGILE FIBER8 (FRA8), IRREGULAR XYLEM8 (IRX8) and IRREGULAR XYLEM9 (IRX9), in the biosynthesis of glucuronoxylan (GX), but the biochemical functions of...
