Novel method for genomic promoter shuffling by using recyclable cassettes.
Genetic elements of interest can be introduced into the Saccharomyces cerevisiae genome via homologous recombination. The current method is to link such an element to a selectable marker gene to be integrated into the target locus. However, the marker gene in this method cannot be reused, which limits repeated manipulation of the yeast genome. An alternative method is to utilize a counterselect...
متن کاملDevelopment of broad-host-range vectors and gene banks: self-cloning of the Pseudomonas aeruginosa PAO chromosome.
A host-vector system for Pseudomonas aeruginosa PAO was developed. Scattered regions of the strain PAO chromosome were cloned by direct selection for complementation of auxotrophs or from a DNA gene bank which contains over 1,000 independently isolated chromosome-vector recombinant plasmids. The use of partially digested chromosomal DNA facilitated the selection of a variety of strain PAO chrom...
متن کاملBroad-Host-Range Plasmid by Electroporation
Methylotrophic bacteria able to grow on one-carbon compounds, such as methanol and monomethylamine, as sole carbon sources have received considerable attention because of their potential commercial applications, including the production of single-cell protein, amino acids, pyrroloquinoline quinone, and poly-3-hydroxybutyrate. The utility of methylotrophs should be increased by the use of recomb...
متن کاملCharacterization of novel virulent broad-host-range phages of Xylella fastidiosa and Xanthomonas.
The xylem-limited bacterium Xylella fastidiosa is the causal agent of several plant diseases, most notably Pierce's disease of grape and citrus variegated chlorosis. We report the isolation and characterization of the first virulent phages for X. fastidiosa, siphophages Sano and Salvo and podophages Prado and Paz, with a host range that includes Xanthomonas spp. Phages propagated on homologous ...
متن کاملMore Is Better: Selecting for Broad Host Range Bacteriophages
Bacteriophages are viruses that infect bacteria. In this perspective, we discuss several aspects of a characteristic feature of bacteriophages, their host range. Each phage has its own particular host range, the range of bacteria that it can infect. While some phages can only infect one or a few bacterial strains, other phages can infect many species or even bacteria from different genera. Diff...
