This study shows that loss of the inaZ gene, which enables ice nucleation activity, restricts bacterial dispersal and leads to genetic and ecological isolation.

This study shows that gene loss and gain in Xanthomonas translucens drive host range shifts, with fitness costs for generalist behavior and enhanced virulence for specialist behavior.

This study uses comparative genomics to analyze genetic diversity and introgression in dwarf lemurs, finding low diversity and signs of ancient admixture linked to hibernation-related genes.
