Linkage analysis of the principal sugars in root exudates of S. tuberosum

Retention time (min) Methylation product
11·53 T-Xylp
16·48 3,5-Araf
19·22 3-Galp
20·47 6-Galp
24·17 3,6-Galp

Linkages were deduced from electron-impact mass spectrometry of partially methylated alditol acetate derivatives.
