TLDR
DNA extracted by this method is suitable for a variety of PCR-based applications (including colony PCR, real-time qPCR, and DNA sequencing) for amplification of DNA fragments of ≤ 3500 bp.
Abstract
We have developed a quick and low-cost genomic DNA extraction protocol from yeast cells for PCR-based applications. This method does not require any enzymes, hazardous chemicals, or extreme temperatures, and is especially powerful for simultaneous analysis of a large number of samples. DNA can be efficiently extracted from different yeast species (Kluyveromyces lactis, Hansenula polymorpha, Schizosaccharomyces pombe, Candida albicans, Pichia pastoris, and Saccharomyces cerevisiae). The protocol involves lysis of yeast colonies or cells from liquid culture in a lithium acetate (LiOAc)–SDS solution and subsequent precipitation of DNA with ethanol. Approximately 100 nanograms of total genomic DNA can be extracted from 1 × 107 cells. DNA extracted by this method is suitable for a variety of PCR-based applications (including colony PCR, real-time qPCR, and DNA sequencing) for amplification of DNA fragments of ≤3500 bp.

Safeguarding CRISPR-Cas9 gene drives in yeast

TL;DR: The efficacy of CRISPR-Cas9 gene drive systems in wild and laboratory strains of the yeast Saccharomyces cerevisiae is reported and concerns surrounding accidental genome editing are addressed by developing and validating methods of molecular confinement that minimize the risk of unwanted genome editing.

New vectors for simple and streamlined CRISPR-Cas9 genome editing in Saccharomyces cerevisiae.

TL;DR: A new sgRNA expression cassette with internal restriction enzyme sites that permit rapid, directional cloning of 20mer guide sequences and a flexible set of vectors based on this design for cloning and expressing sgRNAs (and Cas9) in yeast using different selectable markers are described.

Speciation driven by hybridization and chromosomal plasticity in a wild yeast

TL;DR: It is shown that the rapid evolution of chromosome architecture and an ecological context that led to secondary contact between nascent species drove the formation of an incipient hybrid species with a potentially unique ecological niche in the North American forests.

Selection of non-Saccharomyces yeast strains for reducing alcohol levels in wine by sugar respiration.

TL;DR: The characterization of a collection of non-Saccharomyces yeast strains in order to identify candidate yeast strains for this specific application involved the estimation of respiratory quotient values under aerated conditions, at low pH and high sugar concentrations, calculation of yields of ethanol and other relevant metabolites, and characterization of growth responses to the main stress factors found during the first stages of alcoholic fermentation.

Transformation of intact yeast cells treated with alkali cations.

TL;DR: The transformation efficiency with Cs+ or Li+ was comparable with that of conventional protoplast methods for a plasmid containing ars1, although not for plasmids containing a 2 microns origin replication.

Rapid isolation of yeast genomic DNA: Bust n' Grab

TL;DR: An efficient, inexpensive method for obtaining yeast genomic DNA from liquid cultures or directly from colonies was developed that circumvents the use of enzymes or glass beads, and therefore is cheaper and easier to perform when processing large numbers of samples.

An improved protocol for the preparation of yeast cells for transformation by electroporation

TL;DR: Pretreatment of yeast cells with lithium acetate and dithiothreitol enhances the frequency of transformation by electroporation and results in 15–300‐fold improvement in transformation frequency with several mutant strains of S. cerevisiae that transformed poorly by conventional procedures.

A rapid and reliable DNA preparation method for screening a large number of yeast clones by polymerase chain reaction

TL;DR: Repeated trials could not consistently yield genomic PCR products ranging from 0.3 to 3 kb in size, although some researchers have success in boiling yeast colonies in a small volume of water for 5-10 min, and using either the boiled cells directly or the supernatant from a brief spinning of the boiling cells as a plasmid or YAC source for PCR.
