Although N-acetylglucosamine-1-P uridylyltransferase (GlcNAc1pUT) that catalyzes the final step of hexosamine biosynthetic pathway and is conserved among, organisms, produces UDP-N-acetylglucosamine (UDP-GlcNAc), an essential sugar moiety involved in protein glycosylation structural polymers, its biological function plants remains unknown. In this study, two GlcNA.UT genes were characterized Arabidopsis thaliana. The single mutants glcna.ut1 glcna.ut2 revealed no obvious phenotype, but their...
Abstract Although the nucleolus is involved in ribosome biogenesis, functions of numerous nucleolus-localized proteins remain unclear. In this study, we genetically isolated Arabidopsis thaliana salt hypersensitive mutant 1 (sahy1), which exhibits slow growth, short roots, pointed leaves, and sterility. SAHY1 encodes an uncharacterized protein that predominantly expressed root tips, early developing seeds, mature pollen grains mainly restricted to nucleolus. Dysfunction primarily causes...
