↵a Numbers of polymorphisms per genome are estimations. Sequencing of selected regions of SK1 and Y102 revealed polymorphisms at ̃1/200 bases and 1/350 bases in YJM789. Representative regions may not have been chosen.
↵b In most cases haploid strains were used. SK1 is an isogenic diploid, while EM93 and M1-2 are heterothallic wild strains.
