Table 1. Glycosyl linkages in total mucilage extracted with water.

Linkage abundance was normalized to the absolute monosaccharide levels (µg mg⁻¹ seed) of the same mucilage extracts. Data show means ± sd of three biological replicates per genotype. Boldface values are significantly different from the wild type (Student’s t test, P < 0.05).
