Abstract excerpt
Petite-positivity - the ability to tolerate the loss of mtDNA - was examined after the treatment with ethidium bromide (EB) in over hundred isolates from the Saccharomyces/Kluyveromyces complex. The identity of petite mutants was confirmed by the loss of specific mtDNA DAPI staining patterns. Besides unequivocal petite-positive and petite-negative phenotypes, a few species exhibited temperature sensitive petite...
