The composition of plant cell walls is important in determining cereal end uses. Unlike other widely consumed cereal grains barley is comparatively rich in (1,3;1,4)-β-glucan, a source of dietary fibre. Previous work showed  Cellulose synthase-like  genes synthesise (1,3;1,4)-β-glucan in several tissues.  HvCslF6  encodes a grain (1,3;1,4)-β-glucan synthase, whereas the function of  HvCslF9  is unknown. Here, the relationship between mRNA levels of  HvCslF6 ,  HvCslF9 ,  HvGlbI  (1,3;1,4)-β-glucan endohydrolase, and (1,3;1,4)-β-glucan content was studied in developing grains of four barley cultivars.  HvCslF6  was differentially expressed during mid (8–15 DPA) and late (38 DPA) grain development stages while  HvCslF9  transcript was only clearly detected at 8–10 DPA. A peak of  HvGlbI  expression was detected at 15 DPA. Differences in transcript abundance across the three genes could partially explain variation in grain (1,3;1,4)-β-glucan content in these genotypes. Remarkably narrow sequence variation was found within the  HvCslF6  promoter and coding sequence and does not explain variation in (1,3;1,4)-β-glucan content. Our data emphasise the genotype-dependent accumulation of (1,3;1,4)-β-glucan during barley grain development and a role for the balance between hydrolysis and synthesis in determining (1,3;1,4)-β-glucan content, and suggests that other regulatory sequences or proteins are likely to be involved in this trait in developing grain.
