The virus that causes barley yellow dwarf, the most widespread disease of cereal crops, manipulates its host plant and insect vector to promote its own survival, according to an international team of researchers. The group found that the virus raises the temperature of its host plants along with the heat-tolerance of its aphid vectors to create regions on the plants where aphids can feed free from competing insects. The findings could have implications for crop health as the global climate warms.
