On the role of sugar compartmentation and stachyose synthesis in symplastic phloem loading
… Struktur ist korreliert mit dem Transport von Stachyose und Raffinose neben dem von Saccharose. Im Gegensatz dazu fehlen bei apoplastischen Phloembeladern diese symplastischen Verbindungen zwischen beiden Geweben. Die Anwesenheit von Plasmodesmata macht es für die symplastischen Phloembelader …

The Identification of Quantitative Trait Loci for Sucrose and Stachyose Content in Soybean Seed
… affects the quality and taste of soyfoods, while stachyose is a non-digestible sugar that induces flatulence in non-ruminant animals. Therefore, soybean cultivars with high sucrose and/or low stachyose would be valuable for soyfood and meal markets. The objectives of this study were to identify …

Inheritance of Soluble Oligosaccharides in Soybean Seeds
Sucrose, raffinose, and stachyose make up the majority of the carbohydrates in soybean seeds. While sucrose is a desirable component of soybean seeds, raffinose and stachyose are considered to be anutritive factors and eliminating or reducing them appears to be a beneficial endeavour. The major …

Characterization of raffinose synthase genes in soybean
… is largely composed of sucrose, raffinose, and stachyose, which represent [about]10% of the meal. Both raffinose and stachyose are considered anti-nutritional units; sucrose is considered nutritionally useful. Monogastric animals, including humans, lack the alpha-galactosidase enzyme required …

Mapping Quantitative Trait Loci for Soybean Quality Traits from Two Different Sources
… Both parental lines have high sucrose and low stachyose. The former contains a high level of phytate while the latter is low phytate. The objective of this experiment was to determine whether or not both parents had the same gene(s) for low stachyose. An additional objective was to determine …

Genetic marker analysis of three major carbohydrates in soybean seeds
Carbohydrate content sucrose, raffinose, and stachyose are one of the important seed quality traits in soybean. However, little is known about the genetics of these quantitative traits. Recombinant inbred lines (RIL) were developed from the interspecific hybridization between a Glycine max breeding …

Investigation of Putative Genetic Factors Associated with Soybean [Glycine Max (L.) Merr.] Seed Quality Traits
… in this study include seed sucrose, raffinose, stachyose, and phytate content, seed weight, and maturity. The objective of the first part of this project was to characterize the source of low seed stachyose in soybean line PI200508. Two F2 populations, developed from PI200508 and soybean …

An investigation of sugar feeding by black flies (Diptera: Simuliidae)
… sugar sources. The sugars melezitose and / or stachyose are known to occur in a variety of homopteran honeydews and therefore were used as indicators of honeydew feeding by black flies. In the first study, black flies were collected with insect nets from a stand of Larix larcina heavily …

Elicitoren der Duftstoffemission von Rainfarnpflanzen
… Daten von Fraktion F0/6 führten zur Struktur von Stachyose. Weiterhin wurden im 13C-NMR Spektrum von F0/6 Signale mit chemischen Verschiebungen beobachtet, die im gleichen Bereich wie Stachyose lagen. Es wurde vermutet, dass es sich hierbei um Homologe von Stachyose wie Saccharose, Raffinose und …

Soluble carbohydrates in soybean - discovery of novel genetic resources and evaluation of known mutations
… of soy products. In contrast, raffinose and stachyose (RFOs) create unpleasant intestinal conditions and reduce feed efficiency in non-ruminant animals. Therefore, this research focused on three main topics, including i) the identification of novel genetic resources for high sucrose and low …

Enzymes Involved in the Utilization of the Galactomannan, Guar Gum, by Bacteroides Ovatus
… is grown on galactose, melibiose, raffinose or stachyose. I have purified both of these enzymes to apparent homogeneity. Both enzymes appear to be trimers and have similar pH optima (5.9-6.4 for I, 6.3-6.5 for II). However, (alpha)-galactosidase I has a pI of 5.6 and a monomeric molecular weight …

Economic and chemometric studies to supplement food-grade soybean variety development in the Mid-Atlantic region
… marketed edamame. Sucrose, raffinose, and stachyose sugars hold tremendous implications for utilization of soybean seeds in livestock, soyfood, and probiotics industries. Current sugar phenotyping methods using high-performance liquid chromatography (HPLC) are costly and inefficient. …

BIOCHEMICAL AND MOLECULAR CHARACTERIZATION OF RAFFINOSE FAMILY OLIGOSACCHARIDE (RFO) BIOSYNTHESIS IN LENTIL (Lens culinaris Medik.)
… raffinose synthase (RS; EC 2.4.1.82) and stachyose synthase (STS; EC 2.4.1.67). The expression of RFO biosynthetic genes, corresponding enzyme activity and RFO accumulation were also analyzed during lentil seed development. Gene expression studies in developing seeds necessitated an …

Sensory and Chemical Characteristics of Soymilk Yogurt With Different Yogurt Cultures
… in soy yogurts than dairy yogurts. Raffinose and stachyose were reduced in soy yogurt samples with STDAB and STDL cultures. Although acetaldehyde and lactic acid were present in higher concentrations in the dairy yogurts, the sensory study indicated that soy yogurts were rated higher in overall …

Zur Bedeutung von Saccharose-Transportern in Pflanzen mit offener Phloemanatomie
… meridionalis transportiert im Phloem vor allem Stachyose, Raffinose und Saccharose, während Asarina barclaiana hauptsächlich Saccharose transportiert. Die Konzentrationen von Zuckern und Aminosäuren im Phloemsaft sind in beiden Pflanzenarten so hoch wie in apoplastischen Phloembeladern. Obwohl …

Raffinose family oligosaccharides (RFO) biosynthesis in chickpea (Cicer arietinum L.) seeds
… genotypes. Sucrose (0.60 - 3.59 g/100 g) and stachyose (0.18 − 2.38 g/100 g) were predominant among soluble sugars and RFO, respectively. Analysis of variance revealed a significant impact (P ≤ 0.001) of genotype (G), environment (E), and their interaction (G×E) on seed RFO concentration in …

Composition of Four Selected Arkansas-Grown Non-GMO Soybean Cultivars and the Development of High Protein Beverage Using a Selected Soybean Protein Hydrolysate
… with lowest amount of anti-nutrients including stachyose (42.0 mg/g) and trypsin inhibitor (23.0 TUI/mg). Soy protein isolate (SPI) was prepared using the aqueous extraction (pH = 9), and hydrolyzed at optimal condition of Alcalase concentration 1.0 AU (3.2 µL/g), 50 ºC, and 120 min incubation. …

Characterization of Soybean Germplasm with Modified Phosphorus and Sugar Composition
… with a concomitant decrease in raffinose and stachyose content, further improving the nutritional value of soybean meal. Prior to the release of V99-5089-derived germplasm, germplasm with the MIPS1 mutation was characterized and compared to CX1834-derived germplasm to determine the effects of …
