Host genetic factors shape composition of virus communities

Source: ScienceDaily

Plants can be infected by multiple viruses at once. However, the composition of the pathogen community varies, even if individuals belong to the same species and the same population. Ecologists have now shown that these differences are primarily due to genetic variation among the hosts. The loss of genetic diversity could thus render species more vulnerable to infections and extinction.
