Biomass digestibility is predominantly affected by three factors of wall polymer features distinctive in wheat accessions and rice mutants

^*Significant difference between the two samples of each pair (t-test) at P <0.05; ^**significant difference at P < 0.01 (n = 3). ^aPercentage of the increased or decreased level between the two samples of each pair: subtraction of two samples divided by low value; ^bsamples in the pair with high (H) or low (L) biomass digestibility.
