Recent allopolyploid origin of Zygosaccharomyces rouxii strain ATCC 42981.
Zygosaccharomyces rouxii strain ATCC 42981 has been reported to have two copies of several genes including HOG1 and SOD2, whereas the type strain of Z. rouxii (CBS 732) has only one. To investigate the structure of the ATCC 42981 genome we sequenced random fragments from this genome and compared the data to the type strain. We found that ATCC 42981 contains two versions of the ribosomal RNA arr...
متن کاملOperation of an efficient site-specific recombination system of Zygosaccharomyces rouxii in tobacco cells.
Recombinase encoded by the R gene of pSR1 of Zygosaccharomyces rouxii mediates reciprocal recombination between two specific recombination sites (RSs) to induce excision or inversion of the DNA segment that is flanked by the RSs. We report here that site-specific recombination mediated by this system takes place effeciently in tobacco cells. To monitor the recombination events in tobacco cells,...
متن کاملFormation of 4-hydroxy-2,5-dimethyl-3[2H]-furanone by Zygosaccharomyces rouxii: identification of an intermediate.
The formation of the important flavor compound 4-hydroxy-2,5-dimethyl-3[2H]-furanone (HDMF; Furaneol) from D-fructose-1,6-bisphosphate by the yeast Zygosaccharomyces rouxii was studied with regard to the identification of intermediates present in the culture medium. Addition of o-phenylenediamine, a trapping reagent for alpha-dicarbonyls, to the culture medium and subsequent analysis by high-pr...
متن کاملSecretion of Aspergillus oryzae alkaline protease in an osmophilic yeast, Zygosaccharomyces rouxii.
To produce Aspergillus oryzae alkaline protease (Alp) in an osmophilic yeast Zygosaccharomyces rouxii, we constructed an expression plasmid consisting of the Z. rouxii glyceraldehyde-3-phosphate dehydrogenase (GAPDH) promoter, the prepro-Alp cDNA of A. oryzae, the whole sequence of Z. rouxii plasmid pSR1, and the G418 resistant gene. The resulting plasmid, when introduced into Z. rouxii cells, ...
متن کاملConstruction of High Ethanol Fermenting Halotolerant Hybrid by Intergeneric Protoplast Fusion of Saccharomyces cerevisiae and Zygosaccharomyces rouxii
Saccharomyces cerevisiae M30, a high ethanol producing flocculent strain, was hybridized with Zygosaccharomyces rouxii TISTR1750, a halotolerant non-flocculent strain, by polyethylene glycol induced protoplast fusion. The protoplast fusion of these two yeast genera occurred with frequency of 5.89X10-5. Three fusants, namely RM11, RM37 and RM58, were selected based on their high ethanol fermenta...
