General Information

General Information Comment Organism
malfunction identification of a mutant allele of UDP-glucose epimerase 4 (UGE4)/root hair defective 1/root epidermal bulgar 1, which is a mutant with swollen root epidermal cells and has an altered sugar composition in cell wall polysaccharides. Importantly, these defects including aggregate formation are restored by supplementation of D-galactose in the medium. Intracellular aggregates in the uge4 mutant contains endomembrane markers in the secretory and vacuolar pathways. The lack of UGE4 function affects the structure of the endoplasmic reticulum or trafficking of the endoplasmic reticulum marker. Phenotype, overview. Disruption of the cytoskeleton is not a primary cause of the endomembrane aggregates in the uge4 mutant Arabidopsis thaliana
physiological function UDP-D-galactose synthesis by UDP-glucose 4-epimerase 4 is required for organization of the trans-Golgi network/early endosome in Arabidopsis thaliana root epidermal cells. UDP-D-galactose synthesis by UGE4 is important for endomembrane organization in addition to cell wall structure Arabidopsis thaliana
