Peculiar Plant Virus Causes Bugs To Live Longer
According to research from Penn State, most viral infections have a detrimental effect on an organism’s health, but one plant virus in particular, known as soybean vein necrosis orthotospovirus (SVNV), may actually be beneficial to a particular kind of insect that frequently feeds on soybean plants and can spread the virus to the plant, causing disease.
