Revision as of 09:28, 27 February 2009

This page describes some of the most commonly used yeast lab strains. Much of the information is taken from F. Sherman (2002) Getting started with yeast, Methods Enzymol. 350, 3-41. Other useful papers for strain background information include:

  • Mortimer and Johnston (1986) Genetics 113:35-43 - thoroughly describes the genealogy of strain S288C
  • van Dijken et al. (2000) Enzyme Microb Technol 26:706-714 - compares various characteristics of commonly used lab strains
  • Winzeler et al. (2003) Genetics 163:79-89 - uses SFP (single-feature polymorphisms) analysis to study genetic identity between common lab strains


S288C

Genotype: MATα SUC2 gal2 mal mel flo1 flo8-1 hap1 ho bio1 bio6

Notes: Strain used in the systematic sequencing project, the sequence stored in SGD. S288C does not form pseudohyphae. In addition, since it has a mutated copy of HAP1, it is not a good strain for mitochondrial studies. S288C strains are gal2- and they do not use galactose anaerobically.

The S288C genome was recently resequenced at the Sanger Institute.

JK9-3d

There are a, alpha and a/alpha diploids of JK9-3d with the following genotypes:

Genotypes: JK9-3da MATa leu2-3,112 ura3-52 rme1 trp1 his4

JK9-3dα has the same genotype as JK9-3da with the exception of the MAT locus

JK9-3da/α is homozygous for all markers except mating type

Notes: JK9-3d was constructed by Jeanette Kunz while in Mike Hall's lab. She made the original strain while Joe Heitman isolated isogenic strains of opposite mating type and derived the a/alpha isogenic diploid by mating type switching. It has in its background S288c, a strain from the Oshima lab, and a strain from the Herskowitz lab. It was chosen because of its robust growth and sporulation, as well as good growth on galactose (GAL+) (so that genes under control of the galactose promoter could be induced). It may also have a SUP mutation that allows translation through premature STOP codons and therefore produces functional alleles with many point mutations.

RM11-1a

Genotype: MATa leu2Δ ura3Δ ho::Kan

Notes: RM11-1a is a haploid derivative of Bb32(3), a natural isolate collected by Robert Mortimer from a California vineyard, as in Mortimer et al., 1994. It has high spore viability (80–90%) and has been extensively characterized phenotypically under a wide range of conditions. It has a significantly longer life span than typical lab yeast strains and accumulates age-associated abnormalities at a lower rate. It displays approximately 0.5–1% sequence divergence relative to S288c. More information is available at the Broad Institute website.
