Genetics of a canine transmissible tumour show how the world’s oldest cancer “metastasised” through the global dog population – and captured, maintained and rearranged its mitochondrial DNA along the way.
Hybridization and introgression blur species boundaries and broaden genetic diversity available for adaptation; and widespread introgression underpins the evolution of races of the generalist pathogen Albugo candida that specialise on different host plant species.
Previously uncharacterized long repeat sequences are associated with significant genome variation that can increase fitness and promote antifungal drug resistance in diverse isolates of Candida albicans.
The structure of the promising malaria blood-stage vaccine candidate antigen PfCyRPA and the characterization of a protective epitope are facilitating research on its essential role in parasite invasion, and will guide future epitope-focused vaccine design.
Evidence that the small GUY1 protein is a strong candidate for being a male-determining factor is provided via the establishment of Guy1 transgenic lines of mosquitoes that confer complete and stable female lethality.
