Diurnal patterns of nonstructural carbohydrate (starch, sucrose, and hexose sugars) concentration were characterized in different parts (leaves, petioles, stems, and roots) of vegetative soybean (Glycine max [L.] Merr.) plants. Pronounced changes in all carbohydrate pools were observed in all plant
Activity of pyrophosphate:fructose-6-phosphate phosphotransferase (PFP) was investigated in relation to carbohydrate metabolism and physiological growth stage in mixotrophic soybean (Glycine max Merr.) suspension cells. In the presence of exogenous sugars, log phase growth occurred and the cells
Kinetically improved diacylglycerol acyltransferase (DGAT) variants were created to favorably alter carbon partitioning in soybean (Glycine max) seeds. Initially, variants of a type 1 DGAT from a high-oil, high-oleic acid plant seed, Corylus americana, were screened for high oil content in
Studies were conducted to identify the existence of diurnal rhythms in sucrose phosphate synthase (SPS) activity in leaves of three soybean (Glycine max L. [Merr.]) and two tobacco (Nicotiana tabacum L.) cultivars and the effect of photoperiod (15 versus 7 hours) on carbohydrate partitioning and the
Soybean (Glycine max L. Merril) crop is major source of edible oil and protein for human and animals besides its various industrial uses including biofuels. Phytoplasma induced floral bud distortion syndrome (FBD), also known as witches' broom syndrome (WBS) has been one of the major Pesticides are one of the most widely used pest and disease control measures in plant crops and their indiscriminate use poses a direct risk to the health of populations and environment around the world. As a result, there is a great need for the development of new, less toxic molecules to be
The carbohydrate-binding specificities of lectins purified from Agaricus bisporus (ABA-I), Arachis hypogaea (PNA), Bauhinia purpurea (BPA), Glycine max (SBA), and Vicia villosa (VVA-B4) have been studied by affinity chromatography on columns of the immobilized lectins, and quantitatively analyzed by
Plants have evolved a sophisticated immune system that allows them to recognize invading pathogens by specialized receptors. Carbohydrate-binding proteins or lectins are part of this immune system and especially the lectins that reside in the nucleocytoplasmic compartment are known to be implicated
Relationships between respiration rate and adenylate and carbohydrate pools of the soybean (Glycine max L. Merrill) fruit during rapid seed growth were evaluated. Plants at mid pod-fill were subjected to different concentrations of CO(2) to alter the amount of photosynthate produced and, thus,
Cell-surface carbohydrates of Entamoeba invadens trophozoites were analyzed using (a) a panel of highly purified lectins specific for molecules containing N-acetylglucosamine or sialic acid, N-acetylgalactosamine, galactose, mannose-like residues, and fucose; (b) Escherichia coli K-12 with
The effects of lowering the temperature from 25 degrees C to 2-8 degrees C on carbohydrate metabolism by plant cells are considered. Particular emphasis is placed on the mechanism of cold-induced sweetening in tubers of potato (Solanum tuberosum). Temperatures between 0 and 10 degrees C were shown
Quantitative precipitation studies have shown that the Man/Glc-specific lectin concanavalin A (ConA) forms homogeneous (homopolymeric) cross-linked precipitates with individual asparagine-linked oligomannose and bisected hybrid-type glycopeptides in the presence of binary mixtures of the
Identification of glycans in amphibian testis has shown the existence of N-acetylgalactosamine (GalNAc)-containing carbohydrates. Labeling of the sperm acrosome with GalNAc-binding lectins has allowed the identification of GalNAc-containing glycans in this organelle. Futhermore, this specific
The presence of terminal carbohydrate residues in Enteromyxum leei (Diamant, Lom et Dyková, 1994) Palenzuela, Redondo et Alvarez-Pellitero, 2002 stages in gilthead seabream intestines was studied at light microscopy (LM) and transmission electron microscopy (TEM) level using lectin histochemical
Lectins react with a wide range of different carbohydrates (Table 1). Even so-called monospecific anti-H(O) lectins from Lotus tetragonolobus, Ulex europaeus, and Anguilla anguilla react not only with the anti-H determinant but also with several fucosylated carbohydrates. Consequently, the type of
