Abstract

Three 'killer genes' in one species of fission yeast act selfishly and keep it reproductively isolated from a closely related species.

Keywords: chromosomal rearrangements; meiotic drive; recombination; speciation.

Figures

Figure 1.
Figure 1.. Spore killers interact and determine the survival of spores from S. pombe/S. kambucha hybrids.
(A) Each chromosome in S. kambucha (K1-3) harbours a spore killer gene that works against (black lines) the corresponding chromosome in S. pombe (P1-3). Zanders et al. propose that the P3 chromosome in S. pombe contains a killer gene that works against (black line with question mark) the K3 chromosome in S. kambucha. (B) Combinations of chromosomes generated by random segregation during spore-production by the S. pombe/S. kambucha hybrid, including one aneuploid that inherits copies of chromosome 3 from both parents (bottom). Chromosome combinations predicted to yield viable spores are shown in green, and those predicted to die in yellow. Spore killers are labelled in black.
