BACKGROUND A major hindrance to the development of high yielding biofuel feedstocks is the ability to rapidly assess large populations for fermentable sugar yields. Whilst recent advances have outlined methods for the rapid assessment of biomass saccharification efficiency, none take into account the total biomass, or the soluble sugar fraction of the plant. Here we present a holistic high-thro...

Sweet sorghum has been regarded as a typical species for rich soluble-sugar and high lignocellulose residues, but their effects on biomass digestibility remain unclear. In this study, we examined total 63 representative sweet sorghum accessions that displayed a varied sugar level at stalk and diverse cell wall composition at bagasse. Correlative analysis showed that both soluble-sugar and dry-b...

Soluble sugars and organic acids are important components of fruit flavor and have a strong impact on the overall organoleptic quality of watermelon (Citrullus lanatus) fruit. Several studies have analyzed the expression levels of the genes related to soluble sugar accumulation and the dynamic changes in their content during watermelon fruit development and ripening. Nevertheless, to date, ther...

We evaluated genetic variations in the non-structural carbohydrate (NSC) and the cell-wall components of stem in rice, sorghum, and sugar cane to assess the potential suitability of these gramineous crops for bioethanol production. For NSC, the maximum soluble sugar concentration was highest in sugar cane, followed by sorghum with sucrose. The major NSC in rice was starch, but there were wide v...

Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves. On the other hand, sequential senescence involves leaf senescence that follows an age-related pattern, in which flag leaves are the latest to undergo senescence. The characteristics of sugar metabolism in two sequential senes...

Late-summer starch accumulation in fine roots of poplars (Populus x canadensis Moench.) defoliated by gypsy moth (Lymantria dispar L.) lagged behind that in fine roots of undefoliated trees. If starch concentration declines with age, defoliation-induced changes in root system age structure could be partly responsible for this difference. To test this hypothesis, we measured fine-root starch and...

Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (Triticum aestivum L. CV. Chamran) under Water-Deficit Stress Induced by Polyethylene Glycol as affected by Si application. In this article, the effects of Si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (RWC), electrol...

Studies show that Oryza sativa L. contains a structure named β-glucan with anti cancer properties. In the present study, a tissue culture for rice was carried out and β-glucan content was measured under various sugar and vitamin levels in basic MS medium. Seeds of Hashemi cultivar were cultured on MS medium. Two plant hormones, namely, 2,4-D (0, 1, 1.5, 2 and 3 mg/l) and kinetin (0,0.5, 1, and ...

In this study some selected chemical properties such as total soluble solids, pH, total acidity, formalin index, reduced sugar content and ascorbic acid of major sour cherry cultivated grown in different provinces of Iran corresponding were investigated.  Minerals K+, Na+, Ca2+, Mg2+, Cu2+, Fe2+ and Zn2+ were determine...
