Commonly used auxotrophic markers

This table describes some commonly used auxotrophic markers (along with some novel useful markers); it is based on a table in Brachmann et al. (1998) "Designer deletion strains derived from Saccharomyces cerevisiae S288C: a useful set of strains and plasmids for PCR-mediated gene disruption and other applications." Yeast 14:115-132. Please send e-mail to the curators at SGD at sgd-helpdesk@lists.stanford.edu if you have additions or modifications you would like to suggest.

^bAll trp- strains are cold sensitive (Singh and Manney 1974).
