In potato (Solanum tuberosum L.) suspension cells, the expression of the gene encoding alternative oxidase (AOX) and H2O2 accumulation were induced by treatment with beta-glucan elicitor. The inhibition of catalase activity enhanced both AOX mRNA expression and the production of H2O2, whereas the
The properties and effects of two plant resistance suppressors (1,3-beta-1,6-beta-glucan and a pentasaccharide of xyloglucan origin) involved in the pathosystem of potato (Solanum tuberosum) and the causal agent of blight (Phytophthora infestans (Mont) de Bary) were compared. The microbial
Physicochemical properties of six different varieties of barley and their β-glucans were evaluated along with in vitro bile acid binding and starch digestibility for health beneficial effects. β-Glucan concentrations in less-hulled, beer, black, waxy-naked, naked, and blue barley were 3.44, 3.46,
The activity of lipoxygenase (LOX) in aged potato tuber discs increased by almost 2-fold following treatment of the discs with the fungal elicitor arachidonic acid (AA). Enzyme activity increased above that in untreated discs within 30 min after AA treatment, peaked at 1 to 3 h, and returned to near
Changes in cell wall structure of four strains of Sacccharomyces cerevisiae species (brewer's, baker's and probiotic yeast) after culturing on deproteinated potato juice water (DPJW) with diverse addition of glycerol and different pH were investigated. It allowed to select conditions intensifying
New ideas on production of yeast origin β-glucan preparations for industrial application are attracting interest considering market development of that high-value functional polysaccharide. Sellecting an efficient yeast producer and designing culture conditions are a prerequisite for obtaining high
Starch is of fundamental importance for plant development and reproduction and its optimized molecular assembly is potentially necessary for correct starch metabolism. Re-structuring of starch granules in-planta can therefore potentially affect plant metabolism. Modulation of granule micro-structure
A method is described to screen fungal strains rapidly for overexpression of extracellular beta-1,4-endoglucanase in the presence of high levels of sugar compounds. The semi-quantitative assay utilizes microplates in a 96-well format and an azurine dye covalently cross-linked (AZCL) chromogenic
Starch has unique physicochemical characteristics among food carbohydrates. Starch contributes to the physicochemical attributes of food products made from roots, legumes, cereals, and fruits. It occurs naturally as distinct particles, called granules. Most starch granules are a mixture of 2 sugar
Background: In recent years, consumer interest in low-fat foodstuff while having a clean label and potential benefits over physiological functions has shown a growing trend. β-1,3/1,6-D-glucans (BGs) from Saccharomyces cerevisiae have been recognized as excellent
Culinary-medicinal honey mushroom or Mi-Huan-Ku, Armillaria mellea (AM), is a popular ingredient in the traditional Chinese medicine for treating diseases of geriatric patients. This study aimed to examine the effect of cultured substrates on the mycelial growth of AM and evaluate its antioxidant
To facilitate infection, pathogens deploy a plethora of effectors to suppress basal host immunity induced by exogenous microbe-associated or endogenous damage-associated molecular patterns (DAMPs). In this study, we have characterized family 17 glycosyl hydrolases of the tomato pathogen Cladosporium
β-Glucan is an essential cell wall structural component in most fungi and its helical structure is important for maintenance of cell wall elasticity in fungi. The gene encoding β-1,3-glucan synthase in the entomopathogenic fungus Metarhizium acridum (MaFKS; HQ441252) was cloned. The function of
Tremella fuciformis is a natural edible and medicinal mushroom commercially available in Taiwan. In this study, the effects of initial pH, incubation time, and various media to optimize exopolysaccharide (EPS) production by T. fuciformis were evaluated in shake flasks and a bioreactor. The
A beta-glucan isolated from the mycelial walls of Phytophthora megasperma var. sojae and a glucan purified from yeast extract stimulate the accumulation of phytoalexins in red kidney bean, Phaseolus vulgaris, and stimulate the accumulation of the phytoalexin, rishitin, in potato tubers, Solanum
