title: Some like it hot: citrus tristeza virus strains react differently to elevated temperature.
abstract: Viruses often infect plants as a mixed population. The dynamics of viral populations dictate the success of the infection, yet there is little understanding of the factors that influence them. It is known that temperature can affect individual viruses; could it also affect a virus population? In order to study this, we observed citrus tristeza virus (CTV) populations in different hosts under winter and summer conditions (25 versus 36 °C). We found that only some CTV strains were affected by a higher summer temperature, which lead to a change in CTV population structure, and that this effect was host dependent.
