We present results on the compartmentation o f carbohydrates such as sucrose, glucose, fructose, and mannose in different parts o f an ectomycorrhiza established between Picea abies and Amanita muscaria and compare it with non-mycorrhized fine roots. Lyophilized mycorrhizas and fine roots (< 2 m m length) were dissected into about 0.5 mm thick slices which represent 4 zones o f different physio...

Soluble sugar composition of developing soybean seed (Glycine max L. Merr.) vary with cultivar. This study was conducted to determine the relation between soluble sugar accumulation and associated enzyme activities in developing seed of two soybean cultivars, Williams 82 and Wolverine. Activities of sucrose synthase, invertase, galactinol synthase, and a-galactosidase were compared to soluble s...

BACKGROUND Potato frying quality is a complex trait influenced by sugar content in tubers. Good frying quality requires low content of reducing sugars to avoid the formation of dark pigments. Solanum tuberosum Group Phureja is a valuable genetic resource for breeding and for genetic studies. The sugar content after harvest was analyzed in a germplasm collection of Group Phureja to contribute to...

Trehalose 6-phosphate (Tre6P), the intermediate of trehalose biosynthesis, has a profound influence on plant metabolism, growth, and development. It has been proposed that Tre6P acts as a signal of sugar availability and is possibly specific for sucrose status. Short-term sugar-feeding experiments were carried out with carbon-starved Arabidopsis thaliana seedlings grown in axenic shaking liquid...

date syrup, date concentrate and date liquid sugar are among the products which are produced from low quality dates in date processing plants. the aim of this research was to investigate chemical characteristics and sensory properties of date syrup, date concentrate and date liquid sugar in comparison with sugar (sucrose) solutions and evaluate possible substitution of sucrose with these date b...

The effect of dietary composition on cholesterol formation in the liver of alloxan diabetic rats was studied. Cholesterol formation in these ani mals was maintained at a subnormal level when the diet had a high content of simple sugar (sucrose, glucose or fructose) without fat, but was severely impaired with diets of all other compositions tested . The possible mechanism of maintenance of hepat...

The objective of this study was to evaluate the performance of Sucro Ester 7 (sucrose distearate) as additive for preparing sustained release suppositories of tiaprofenic acid. Suppocire AIM (semi-synthetic glycerides) was used as suppository base and formulations were prepared containing different ratios of sugar ester: Suppocire AIM. Content uniformity, disintegration time and in vitro releas...

Defoliation produced by abiotic factors and the subsequent re-growth can reduce sugar beet (Beta vulgaris L.) sucrose content and final sugar yield. Field experiments were conducted during 2003 and 2004 growing seasons in the farm of Hellenic Sugar Industry SA, Larissa factory, central Greece. Three sugar beet cultivars (Rival, Europa and Corsica) were ordinary irrigated till the beginning of J...

Aluminium is well known to inhibit plant elongation, but the role in this inhibition played by water relations remains unclear. To investigate this, tobacco (Nicotiana tabacum L.) suspension-cultured cells (line SL) was used, treating them with aluminium (50 microM) in a medium containing calcium, sucrose, and MES (pH 5.0). Over an 18 h treatment period, aluminium inhibited the increase in fres...
