The serological relationships of Potato Virus Y (PVY) isolates belonging to the pepper pathotypes 0, 1 and 1-2 were established by enzyme-linked immunosorbent assay (ELISA). PVY pepper pathotypes did not react with monoclonal antibodies which typically recognize non-pepper strains within the PVY group, leading to discrimination between these two groups of(More)
 We examined the role of several amino acid residues located at the N-terminus of the tobacco etch potyvirus (TEV) helper component-proteinase (HC-Pro) in virus transmissibility by aphids. Site-directed mutagenesis resulted in changes affecting amino acids that appear highly conserved among a number of potyviruses. The TEV HC-Pro amino acid residues Gly343,(More)
The tearing of the collagen fibers of biological materials utilized in implants or bioprostheses is an important, and sometimes early cause of the failure of these devices. We studied the force necessary to propagate a tear in a biomaterial, pericardium from young bulls, and the influence of the suture. An Elmendorf pendulum capable of measuring the force(More)
