Title Evidence for mitochondrial DNA polymorphism and uniparental inheritance in the cellular slime mold Polysphondylium pallidum: effect of intraspecies mating on mitochondrial DNA transmission.
Journal Genetics
Abstract Restriction fragment length polymorphisms (RFLPs) were used as markers to monitor mitochondrial inheritance in the cellular slime mold, Polysphondylium pallidum. When two opposite mating types (mat1 and mat2) of closely related strains were crossed, all the haploid progeny regardless of mating type inherited their mitochondrial DNA from the mat2 parent only. When opposite mating types from more distantly related strains were crossed, most of the progeny also inherited their mitochondrial DNA from the mat2 parent, but some inherited their mitochondrial DNA from the mat1 parent. In both cases however, the transmission of mitochondrial DNA was uniparental, since in every individual progeny only one type of mitochondrial DNA exists. Moreover, in crosses involving more distantly related strains all the progeny of a single macrocyst were shown to contain the same type of mitochondrial DNA. These findings are discussed in regard to mechanisms of transmission and the possible involvement of nuclear genes in the control of transmission of mitochondrial DNA in Polysphondylium.
