• leaf
  • Delayed planting has been suggested to reduce density of the bean leaf beetle Cerotoma trifurcata (Förster), the principal vector of Bean pod mottle virus. (iastate.edu)
  • mosaic
  • The first virus to be discovered (see below) was Tobacco mosaic virus (TMV). (wikipedia.org)
  • The discovery of plant viruses causing disease is often accredited to A. Mayer (1886) working in the Netherlands demonstrated that the sap of mosaic obtained from tobacco leaves developed mosaic symptom when injected in healthy plants. (wikipedia.org)
  • In 1898, Martinus Beijerinck, who was a Professor of Microbiology at the Technical University the Netherlands, put forth his concepts that viruses were small and determined that the "mosaic disease" remained infectious when passed through a Chamberland filter-candle. (wikipedia.org)
  • coat
  • The data also demonstrated that seed coat mottling, which can result in financial penalties to producers, was unreliable for predicting relative amounts of virus in seed. (iastate.edu)
