host, if not bean leaf beetles. Being a non-persistent virus, when the bean beetle feeds on infected tissue, the virus is carried around the mouthparts of the insect to the next host the beetle feeds on. The feeding creates an easy opening for the virus to get in, after which the virus begins its attack on the host. The virus enters the host cell and replicates, then spreads to the surrounding cells, making its way through the plant systemically, as the plant develops symptoms. RNA-1 codes for replication proteins, and the proteinase and putative helicase are linked to symptomology of the virus. RNA-2 codes for coat and movement proteins, which are important in the cell-to-cell movement of BPMV. Once the virus reaches the seed, it is believed that it is harbored in the seed coat, not actually infecting the embryo. This would result in the virus waiting for an opening to infect the new plant, such as the germination period where damage to the cotyledons can take place. Seed-seedling transmission occurrences are low. BPMV can also survive on an alternate host, which the beetle would transfer to the soybeans. (Byamukama, 2008) Agronomic Impact BPMV infected seed that is planted will grow into an infected seedling which have the most severe yield losses, between 10-40% reductions have been reported. In addition to yield, BPMV can reduce grain quality through protein and oil content, reduced seed quality and performance (discolored appearance, low germination and seedling vigor), delayed plant maturation, and the predisposition to other stresses and diseases (such as infection of Phomopsis fungus decreasing germination of seed and seedling vigor). (Smith, Wisconsin Field Crops Pathology) (University of Minnesota Extension, 2016) Management BPMV cannot be removed from the plant once infected, so it is important to take action to avoid the virus, or prevent it from spreading. There are genetic, cultural, and chemical options which should be used together in an integrated pest management plan, in addition to managing the vector presence as well. Genetic Resistance: Partial resistance to BPMV is available in some soybean varieties meaning there is less yield reductions, lower rates of green stem and seed mottling. Varieties with higher resistance are in development, thus commercially unavailable at this time. Other plants in the genus Glycine have been identified as immune, so it may be possible in the future to develop resistant lines in soybeans by interspecific crosses (University of
