Potato Virus Y (PVY)resistance genepathotypes and systemic necrosisC. annuum L. 'Serrano Criollo de Morelos-334' (SCM-334) is a well-known source of resistance against pepper diseases, including Potato Virus Y (PVY). In this work, inheritance studies involving 'SCM-334' and related to PVY...
HITHERTO the most convenient test for the presence of potato virus Y (Solanum virus 2) has been by sap inoculation to tobacco, and no plant has been recorded on which the virus produces local lesions visible without decolorizing the leaf and staining with iodine....

Surveys for virus disease in potato (Solanum tuberosum L.) ware crops were completed over three successive seasons. Overall mean incidence of viruses in plants derived from pathogentested (PT) seed lines and nonPT seed lines was 2.2 and7.6% (1991),4.1 and 11.2% (1992), and 2.5 and 6.5%...
violaceus plants in Beijing, China, showed viral disease symptoms, including mosaic, malformation and colour-breaking. ACP-ELISA and PCR analyses of samples from infected plants revealed the presence of Potato virus X (PVX). This is thought to be the first report of the natural occurrence of ...

The CD4 positive T-cell line CEM-ss was used as indicator momolayer cells for the microtiter syncytium-forming assay. The H9 cell line was used in suspension cultures for assays of p24 expression and viral-associated RT activity. HIV-1 virus stock was obtained from R. Gallo. The virus wa...
The complete coat protein (cp) gene sequence of eighty Tomato leaf curl New Delhi virus-[potato] (ToLCNDV-[potato]) isolates collected from eleven states were determined. Phylogenetic analysis based on cp gene grouped the isolates into two major clades (I & II) and they shared 95.9-100.0% ...
