I know that petites often are white even in an ade2 background, but it's
also true that even in ADE2 backgrounds, colonies or patches of petites
look whiter (less "creamy"). I think I was once told this is because of
the loss of mitochondrial cytochromes... any validation to this
hypothesis, or ideas to the contrary?
To get at the point another way, I found some EMS mutants that are just
plain whiter (less creamy) on rich media. One is a petite, others are
not. None has an obvious growth defect on rich media. Has anyone heard of
mutations that change the appearance (in terms of "creaminess") of
cerevisiae strains?
Thanks,
Michael
