“…Similar results were obtained in maize stover that a higher cellulose content was closely associated with a higher hemicelluloses content [35]. These results suggest that cellulose, hemicelluloses (mainly ADH), and AIL might simultaneously be synthesized in secondary cell wall fraction in wheat straw.…”

“…The arabinoxylan content in wheat grains ranged between 4.07% and 6.02% of dry matter among five genotypes (Lempereur et al, 1997). The range of the neutral detergent fiber content (composed of mainly cellulose, hemicellulose, and lignin) in wheat straw is between 68.18% and 81.97% of dry matter and the range of the calculated hemicellulose content is between 24.91% and 30.70% among 15 genotypes (Habib et al, 1995). Interestingly, an inverse relationship between WSCs and neutral detergent fiber contents has been observed in the shoot of ryegrass (Lolium perenne) varieties (Smith et al, 2002).…”

Molecular Dissection of Variation in Carbohydrate Metabolism Related to Water-Soluble Carbohydrate Accumulation in Stems of Wheat

Water-soluble carbohydrates (WSCs; composed of mainly fructans, sucrose [Suc], glucose [Glc], and fructose) deposited in wheat (Triticum aestivum) stems are important carbon sources for grain filling. Variation in stem WSC concentrations among wheat genotypes is one of the genetic factors influencing grain weight and yield under water-limited environments. Here, we describe the molecular dissection of carbohydrate metabolism in stems, at the WSC accumulation phase, of recombinant inbred Seri/Babax lines of wheat differing in stem WSC concentrations. Affymetrix GeneChip analysis of carbohydrate metabolic enzymes revealed that the mRNA levels of two fructan synthetic enzyme families (Suc:Suc 1-fructosyltransferase and Suc:fructan 6-fructosyltransferase) in the stem were positively correlated with stem WSC and fructan concentrations, whereas the mRNA levels of enzyme families involved in Suc hydrolysis (Suc synthase and soluble acid invertase) were inversely correlated with WSC concentrations. Differential regulation of the mRNA levels of these Suc hydrolytic enzymes in Seri/Babax lines resulted in genotypic differences in these enzyme activities. Down-regulation of Suc synthase and soluble acid invertase in high WSC lines was accompanied by significant decreases in the mRNA levels of enzyme families related to sugar catabolic pathways (fructokinase and mitochondrion pyruvate dehydrogenase complex) and enzyme families involved in diverting UDP-Glc to cell wall synthesis (UDP-Glc 6-dehydrogenase, UDP-glucuronate decarboxylase, and cellulose synthase), resulting in a reduction in cell wall polysaccharide contents (mainly hemicellulose) in the stem of high WSC lines. These data suggest that differential carbon partitioning in the wheat stem is one mechanism that contributes to genotypic variation in WSC accumulation.Water-soluble carbohydrates (WSCs) can accumulate in the stem and leaf sheath of cool-season cereals (e.g. wheat [Triticum aestivum], barley [Hordeum vulgare], and oats [Avena sativa]) during the period from stem elongation to the early phase of grain filling and serve as temporary carbohydrate reserves, commonly called the stem carbohydrate reserves (Schnyder, 1993;
