It is well known that glycogen and trehalose accumulate in yeast under nutrient starvation or entering into the stationary phase of growth, and that high levels of trehalose are found in heat-shocked cells. However, effects of various types of stress on trehalose, and especially on glycogen, are poorly documented. Taking into account that almost all genes encoding the enzymes involved in the me...

* Root exudates play a key role during the presymbiotic growth phase and have been shown to stimulate hyphal branching and the catabolic metabolism of arbuscular mycorrhizal (AM) fungal spores. * Here, the effect of root exudates on presymbiotic growth, uptake of exogenous carbon and transcript levels for genes putatively involved in the carbon metabolism of germinating spores were determined. ...

Wheat cultivation makes an important contribution to human nutrition. Trehalose synthesis plays a role in the tolerance drought stress. A bifunctional TPS-TPP enzyme gene from yeast was used obtain transgenic wheat plants increase trehalose synthesis. Mature embryos were transformed using pGreen rd29A::TPS1-TPS2 or 35S::TPS1-TPS2 constructs. The transgene presence mature leaves of T3 confirmed ...

Bay laurel (Laurus nobilis) is an agriculturally and economically important dioecious tree in the basal dicot family Lauraceae used in food and drugs and in the cosmetics industry. Bay leaves, with their abundant monoterpenes and sesquiterpenes, are used to impart flavor and aroma to food, and have also drawn attention in recent years because of their potential pharmaceutical applications. To i...

Sugarcane (Saccharum spp. hybrid) is a noteworthy crop in the world for sugar and bioenergy production. In present study, transcriptomic analysis was steered high sucrose mutant Guixuan B9 (GXB9) low mother genotype of sugarcane during accumulating stage. A total 112,170 unigenes were obtained, 106,026 (94.52%) annotated by using available public databases nonredundant, Gene ontology, COG, Kyot...

Trehalose is an unusual non-reducing disaccharide that plays a variety of biological roles, from food storage to cellular protection from environmental stresses such as desiccation, pressure, heat-shock, extreme cold, and oxygen radicals. It is also an integral component of the cell-wall glycolipids of mycobacteria. The primary enzymatic route to trehalose first involves the transfer of glucose...

Magnaporthe oryzae (M. oryzae) is a fungal pathogen and the causal agent of rice blast disease. Previous lipidomics analysis of M. oryzae demonstrated that trehalose, a carbohydrate common to various fungi and algae, is thought to be involved in the possible conversion of glycogen into triacylglycerides for energy, an important step in the pathogenesis of M. oryzae. A key enzyme responsible for...
