A trehalose-6-phosphate synthase gene from Phellinus igniarius
Trehalose, an important disaccharide in fungal spores, plays important role in protects against many environmental stresses, such as heat and salt. In this study, a gene (PiTPS) encoded trehalose-6-phosphate synthase was isolated from Phellinus igniarius (L.: Fr.) Quél, a basidiomycete fungus belonging to the family Polyporaceae. It contains many bioactive compounds that have been reported to p...
متن کاملTHE PRODUCTION OF GLUCOAMYLASE BY ASPERGILLUS NIGER UNDER SOLID STATE CONDITIONS (RESEARCH NOTE)
In this study, Glucoamylase production by Aspergillus Niger was investigated under solid state conditions with low cost by-products of agricultural processes as substrate. Highest enzyme production was observed when a combination of wheat bran (WB) and corn flour (CF) was used as compared to WB+ rice bran, WB+ rice flour and WB alone. Different additions of (CF) were tested and WB+ 10% CF showe...
متن کاملDisruption of TPS2, the gene encoding the 100-kDa subunit of the trehalose-6-phosphate synthase/phosphatase complex in Saccharomyces cerevisiae, causes accumulation of trehalose-6-phosphate and loss of trehalose-6-phosphate phosphatase activity.
Preparations of the trehalose-6-phosphate synthase/phosphatase complex from Saccharomyces cerevisiae contain three polypeptides with molecular masses 56, 100 and 130 kDa, respectively. Recently, we have cloned the gene for the 56-kDa subunit of this complex (TPS1) and found it to be identical with CIF1, a gene essential for growth on glucose and for the activity of trehalose-6-phosphate synthas...
متن کاملXylanase Production under Solid State Fermentation by Aspergillus niger
Central composite orthogonal design was applied to quantify relations of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...
متن کاملTrehalose mediated growth inhibition of Arabidopsis seedlings is due to trehalose-6-phosphate accumulation.
Trehalose-6-phosphate (T6P) is required for carbon utilization during Arabidopsis development, and its absence is embryo lethal. Here we show that T6P accumulation inhibits seedling growth. Wild-type seedlings grown on 100 mm trehalose rapidly accumulate T6P and stop growing, but seedlings expressing Escherichia coli trehalose phosphate hydrolase develop normally on such medium. T6P accumulatio...
