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...

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...

Few studies have evaluated vegetable soybean for sugar content at the green pod stage. Information on combining ability and type of gene action that governs inheritance of seed traits can help breeders to select suitable parents and devise an appropriate breeding strategy. Ten vegetable soybean accessions were crossed in a complete diallel mating design. Parent lines and F2 and F3 progenies wer...

A candidate gene approach has been used as a first step to identify the molecular basis of quantitative trait variation in potato. Sugar content of tubers upon cold storage was the model trait chosen because the metabolic pathways involved in starch and sugar metabolism are well known and many of the genes have been cloned. Tubers of two F(1) populations of diploid potato grown in six environme...

Partitioning of dry matter (DM) in sugarcane is of interest for two fundamental reasons. Firstly sugar production depends directly on partitioning of biomass to the stalk and then to sucrose stored in the stalk. Secondly, various DM components of the stalk and particularly sucrose concentration are used to calculate the value of cane consignments delivered to the mill (Berding, 1997). The value...

the use of chlorophyll fluorescence (chlf) technique was evaluated on nondestructive measurement of sugar content during fruit development. multivariate models, principal component analysis (pca), and partial least-squares regression (plsr), were developed for the classification and prediction of fructose, glucose, and sucrose in fig fruits. the results of this study showed a significant correl...

Sugar content is the major determinant of both fruit quality and consumer acceptance in melon (Cucumis melo L), and is a primary target for crop improvement. Near-isogenic lines (NILs) derived from the intraspecific cross between a "Piel de Sapo" (PS) type and the exotic cultivar "Songwhan Charmi" (SC), and several populations generated from the cross of PS × Ames 24294 ("Trigonus"), a wild mel...

Background: Honey has a lot of reputation because of its supposed medicinal properties. In this study, Hydroxymethylfurfural (HMF), sugars, and Fructose/Glucose ratio of honey in Bangladesh were assessed for adulteration and authenticity evaluation. Methods: Seventy honey samples collected from different districts of Bangladesh were analyzed by High Performance Liquid Chromatography (HPLC) for...

Sweet corn (Zea mays L.) producers desire high yields and high sugar content in the endosperm. High irrigation levels result in high yield, but their effect on sugar content is unclear. The effects of two irrigation levels, standard and stressed on endosperm sugar content were evaluated using three sugary1 hybrids over 2 years. No significant differences were found among the treatments when ave...

In a four-year experiment, five nitrogen rates (0, 60, 120, 180 and 240 kg N ha-1) were tested over irrigated sugar beets grown on clays, underMediterranean conditions, in centralGreece. There, sugar beets are commonly grown under water shortages, high temperatures and high soil Na concentrations. Contrary to previous reports, N rates did not affect significantly population density (as asse...
