Landscape-scale variation in an anthropogenic factor shapes immune gene variation within a wild population.

abstract：:Microbes have evolved ways of interference competition to gain advantage over their ecological competitors. The use of secreted killer toxins by yeast cells through acquiring double-stranded RNA viruses is one such prominent example. Although the killer behaviour has been well studied in laboratory yeast strains, our ...
