Commonly used strains
This table 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
|
MATα SUC2 gal2 mal mel flo1 flo8-1 hap1 |
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. |

In addition, the original W303 strain contains the rad5-535 allele. | W303 constructed by Rodney Rothstein (see detailed notes from RR). bud4 info: Voth, W.P. et al.

MATa {leu2-3,112 trp1-1 can1-100 ura3-1 ade2-1 his3-11,15} | W303-1A possesses a ybp1-1 mutation (I7L, F328V, K343E, N571D) which abolishes Ybp1p function, increasing sensitivity to oxidative stress. |
