the aim of the study was to evaluate changes of sorbitol, glucose, fructose, sucrose, and total sugars of plum fruits in different years under different climatic conditions i.e. air temperature and precipitation. the cultivars investigated in the research were: topstar, toptaste, jojo, haganta, tophit, and top 2000. the fruits were harvested at optimal stage of maturity in the experimental orch...

To change the hexose-to-sucrose ratio within phloem cells, yeast-derived cytosolic invertase was expressed in transgenic potato (Solanum tuberosum cv. Desirée) plants under control of the rolC promoter. Vascular tissue specific expression of the transgene was verified by histochemical detection of invertase activity in tuber cross-sections. Vegetative growth and tuber yield of transgenic plants...

xylitol is the first rare sugar that has global market due to having beneficial health properties and being an alternative to current conventional sweeteners. biotechnological production of xylitol by candida tropicalis dsm 7524 as an alternative to chemical method for the fermentation of xylose to xylitol was studied. banana peel was used as a substrate for xylitol production. hydrolysate was ...

Sucrose is a necessary external carbon substrate for in vitro microtuber induction and development. In this study, we determined the correlation between sucrose and microtuber formation in potato by investigating the role and significance of sucrose in the medium and the origin of explants, as well as the potential function of sucrose in microtuber formation in vitro. Sucrose strongly influence...

We have examined the mechanism of the carbohydrate induction of rat hepatic mRNA-S14 to the intragastric administration of sucrose and its constituent hexoses, fructose and glucose. A maximal sucrose response (26-fold) was obtained with 2 ml of 60% sucrose/100 g of body weight, yet equimolar concentrations of fructose and glucose were not able to reproduce the response. Fructose yielded less th...

Sugar accumulation is a common metabolic response under drought stress conditions. However, studies on the underlying molecular mechanisms of sugar accumulation under stress remain restricted. This study explores the role of sucrose metabolizing proteins in conferring tolerance to drought-induced hyperosmotic stress, and ultimately osmotic adjustment in sorghum. The effect of stress on sugar co...

the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

We describe the development and application of an expressed sequence tag (EST)-derived restriction fragment length polymorphism (RFLP) marker for sugarcane elite genotypes which can be used for quantitative trait loci (QTL) tagging for sugar content. EST-derived RFLP markers for proteins involved in sucrose metabolism have been used in Southern analysis for mapping and gene tagging in elite sug...

In the present study, the effects of substituting sucrose with maltitol and xylitol as bulking agents in compound milk chocolate were examined in relation to their physico-chemical, rheological and sensory characteristics. Standard reference chocolate was made using sucrose. The Casson mathematical model was the best fitting model for predicting rheological properties. Compared with chocolate s...
