Abstract
- Molecular imaging of glycans has been actively pursued in animal systems for the past decades. However, visualization of plant glycans remains underdeveloped, despite that glycosylation is essential for the life cycle of plants. Metabolic glycan labeling in Arabidopsis thaliana by using N-azidoacetylglucosamine (GlcNAz) as the chemical reporter is reported. GlcNAz is metabolized through the salvage pathway of N-acetylglucosamine (GlcNAc) and incorporated into N-linked glycans, and possibly intracellular O-GlcNAc. Click-labeling with fluorescent probes enables visualization of newly synthesized N-linked glycans. N-glycosylation in the root tissue was discovered to possess distinct distribution patterns in different developmental zones, suggesting that N-glycosylation is regulated in a developmental stage-dependent manner. This work shows the utility of metabolic glycan labeling in elucidating the function of N-linked glycosylation in plants. [ABSTRACT FROM AUTHOR]
