Figure 5. EIC for the L-Fuc modified oligosaccharides from Arabidopsis root AGP extracts of wild-type (black line), fut4 (red line), fut6 (blue line) and fut4/fut6 (magenta line) plants.

Although all three fucosylated oligosaccharides were detected for wild-type, fut4 and fut6 samples, no FucAraGal₃ and FucAraGal₄ were detected from AGP root extracts from fut4/fut6 plants and very small amount of FucPent₂Gal₃ oligosaccharide was detectable in root AGP extracts from fut4/fut6 plants but its abundance relative to wild-type is significantly reduced.
