Proportion of N-glycan structures found in Arabidopsis wild-type N-glycopeptides. The 1110 N-glycopeptides identified from rosette, stem, and flower samples were divided into six structural classes (immature, high-mannose, hybrid, complex, paucimannose, truncated, and GlcNAc only) based on previous analyses (supplemental Table S2). The areas (XICs) for each N-glycan structure from a given experiment (n = 8) were extracted and used to calculate the proportion for each structural class. The numbers are the percentage of total normalized monoisotopic peak area for specific glycan types with S.E. The most common representative structure for each N-glycan class is shown.
