In this chapter we have provided instructions for transforming yeast by a number of variations of the LiAc/SS-DNA/PEG method for a number of different applications. The rapid transformation protocol is used when small numbers of transformants are required. The high efficiency transformation protocol is used to generate large numbers of transformants or to deliver DNA constructs or oligonucleoti...
Among the diverse alkaliphilic Bacillus strains, only a little have been reported to be genetically transformed. In this study, an efficient protoplast transformation procedure was developed for recalcitrant alkaliphilic Bacillus sp. N16-5. The procedure involved polyethylene glycol-induced DNA uptake by the protoplasts and subsequent protoplast regeneration with a developed hard agar regenerat...
Transformation efficiencies for Pichia pastoris are usually several orders of magnitude below those for other yeast. We report here that pretreatment of P. pastoris with 0.1 M lithium acetate (LiAc) and 10 mM dithiothreitol (DTT) before electroporation increased transformation efficiency approximately 150-fold. DTT alone enhanced the transformation efficiency up to 20-fold, but LiAc alone had l...
Many researchers have developed various methods for in-planta or floral dip transformation of Arabidopsis thaliana, one of the simple protocol and widely used to produce transgenic Arabidopsis. As the efficiency and ease of getting a transformant is very much time consuming effort and less number of the transformants people get, we have developed a little modified transformation protocol to avo...
Bifidobacterium longum 105-A shows high transformation efficiency and allows for the generation of gene knockout mutants through homologous recombination. Here, we report the complete genome sequence of strain 105-A. Genes encoding at least four putative restriction-modification systems were found in this genome, which might contribute to its transformation efficiency.
