Ethyl Methane Sulfonate (EMS) Mutagenesis Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4180

Category: Yeast Protocols: Yeast Genetics Protocols

Protocol describes mutagenesis of yeast with ethyl methane sulfonate (EMS). It causes approximately 40-70% cell death in most haploid laboratory strains, a level of cell killing that is commonly used in mutant hunts with haploid strains. - [Read Ethyl Methane Sulfonate (EMS) Mutagenesis Protocol]

Genome-Wide Analysis of Protein-Protein Interactions Using a Two-Hybrid Array - http://www.cshprotocols.org/cgi/content/abstract/2006/23/pdb.prot4562

Category: Yeast Protocols: Yeast Protein Protocols: Yeast Protein Protein Interactions Protocols

This procedure capitalizes on the asexual/sexual reproductive cycle of yeast cells. Laboratory yeast strains can be maintained indefinitely by asexual reproduction as one of two haploid mating types, MATa or MAT{alpha}. - [Read Genome-Wide Analysis of Protein-Protein Interactions Using a Two-Hybrid Array]

Making a Tetrad Dissection Needle Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4182

Category: Yeast Cell Culture Protocols: Yeast Sporulation Protocols

Microneedles attached to micromanipulators are used in the dissection of tetrads, isolation of zygotes from populations of mating haploid cells, and manipulation of individual cells. - [Read Making a Tetrad Dissection Needle Protocol]

Picking Zygotes Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4183

Category: Yeast Cell Culture Protocols: Yeast Sporulation Protocols

Zygotes can be identified by their unique morphology. They can be easily separated away from nonmated cells using a micromanipulator. This method provides an alternative to the selection of diploid cells on a medium that prevents the growth of haploid parent cells. - [Read Picking Zygotes Protocol]

Plant DNA Extraction Protocol - http://wheat.pw.usda.gov/~lazo/methods/lazo/dnaplmy.html

Category: Plant Biology Protocols: Plant DNA RNA Isolation Protocols

A. thaliana has a very small haploid genome and this makes obtaining DNA somewhat difficult. The most notable problem is that DNA is usually contaminated with polysaccharide which inhibit restriction enzymes as well as other DNA modifying enzymes. This problem is most easily solved by using young plants which have not accumulated as much polysaccharide as older plants. The best results are obtained with plants that are two to three weeks post germinated. - [Read Plant DNA Extraction Protocol]
