Research Responsibilities
Soybean plants are susceptible to infection by several different viruses. A
recent survey of virus incidence in soybean in Illinois identified Bean pod
mottle virus (BPMV), Alfalfa mosaic virus (AMV), Soybean dwarf
virus, Tobacco ringspot virus, and Soybean mosaic virus (SMV)
in decreasing order of prevalence. The incidences of virus infections are
dependent upon the prevalence of insect vectors and the availability of infected
source plants. For example, recent increases in bean leaf beetle populations
were accompanied by high incidences of BPMV infections in soybean. Similarly,
dramatic increases in the incidences of AMV and Cucumber mosaic virus in
snap beans in the Great Lakes region have been associated with large populations
of the Asian soybean aphid (Aphis glycines), which spread throughout
the soybean growing regions of North America after being discovered in the Midwest
in 2000. Because the presence of large populations of the Asian soybean
aphid has the potential to significantly increase the incidence of aphid-borne
virus diseases in soybean, disruption of vector transmission could reduce the
losses caused by soybean virus infections. Seed transmission is thought
to be the most important source of virus inoculum for SMV infections. Hence,
resistance to seed transmission of seed-borne viruses, like SMV, could provide
effective control of virus infections in soybean even when vector populations
are high. The objectives of my research include detection and characterization
of soybean-infecting viruses and identification of viral and host determinants
of horizontal and vertical transmission of soybean viruses.
