Chromosomal rearrangements as a major mechanism in the onset of reproductive isolation in Saccharomyces cerevisiae.

ABSTRACT: Understanding the molecular basis of how reproductive isolation evolves between individuals from the same species offers valuable insight into patterns of genetic differentiation as well as the onset of speciation [1, 2]. The yeast Saccharomyces cerevisiae constitutes an ideal model partly due to its vast ecological range, high level of genetic diversity [3-6], and laboratory-amendable sexual reproduction. Between S. cerevisiae and its sibling species in the Saccharomyces sensu stricto complex, reproductive isolation acts postzygotically and could be attributed to chromosomal rearrangements [7], cytonuclear incompatibility [8, 9], and antirecombination [10, 11], although the implication of these mechanisms at the incipient stage of speciation remains unclear due to further divergence in th
