| | ARS Project: ETIOLOGY, EPIDEMIOLOGY, PATHOGENESIS, AND VECTOR BIOLOGY OF SUGARBEET AND VEGETABLE VIRUSES (407682) |
 | | To improve plant productivity by increasing our understanding of the etiology, epidemiology, pathogenesis and vector biology of sugarbeet, vegetable, and interrelated crop and weed viruses with emphasis on ecologically sound management practices for control of virus diseases. |
 | | Studies on lettuce dieback, an emerging soil-borne virus disease of lettuce, will focus on determination of epidemiological factors affecting symptom development, spread and development and characterization of sources of resistance. |
 | | Studies on virus yellows of sugarbeet will focus on developing tools for monitoring outbreaks of yellowing viruses, as well as characterization of molecular mechanisms of synergistic interactions leading to increased disease severity in the yellows complex. |
