Formatted abstract Particulate enzymes from suspension-cultured ryegrass (Lolium multiflorum Lam.) endosperm cells incorporated glucosyl residues from UDP-glucose and GDP-glucose into β-glucans. Three types of β-glucans were produced from UDP-glucose: 1,3-β-glucan; 1,4-β-glucan; and mixed-linkage 1,3;1,4-β-glucan. As in other systems, relatively more 1,4-β-glucan was produced from a low (10 micromolar) UDP-glucose concentration, and relatively more 1,3-β-glucan was produced from a high (1 millimolar) UDP-glucose concentration. However, in ryegrass, 1,3;1,4-β-glucan represented a major proportion of the products at both low and high UDP-glucose concentrations. The arrangement of linkages in the 1,3;1,4-β-glucan was different at the two concentrations; at the low UDP-glucose concentration, more sequences of three consecutive 1,4-linkages were produced.
