acetyl-CoA + D-glucosamine 6-phosphate Oryza sativa enzyme is involved in de novo UDP-N-acetylglucosamine biosynthesis. Aberrant root morphology of the gna1 mutant includes shortening of roots, disruption of microtubules, and shrinkage of cells in the root elongation zone and causes a temperature-sensitive defect in root elongation CoA + N-acetyl-D-glucosamine 6-phosphate
