background: potyviruses are accounted for 40% of viral diseases of various crops including vegetables and legumes. potyviruses can be transmitted through plant sap, seeds and many aphid species. due to ease of spread of these viruses detection of such viruses are crucial as to the control of the incited diseases. objectives: this study compared the efficiencies of two couples of primers in thei...

Watermelon mosaic virus was first reported in 1965 from the Rio Grande Valley, TX. We report here the first complete genome sequence of a watermelon mosaic virus isolate from watermelon collected from the Rio Grande Valley of Texas.

Ali, A., Mohammad, O., and Khattab, A. 2012. Distribution of viruses infecting cucurbit crops and isolation of potential new virus-like sequences from weeds in Oklahoma. Plant Dis. 96:243-248. Field surveys were conducted from 2008 to 2010 to detect and determine the incidence of viruses in the major cucurbit-growing areas of Oklahoma. In total, 1,049 symptomatic leaf samples (890 from cucurbit...

Since 1999, "emerging" (EM) strains of Watermelon mosaic virus (WMV) have been detected in cucurbit crops of southeastern France, probably as a result of recent introductions. Population genetic approaches were used to study the structure of EM isolates in southeastern France and to identify factors involved in their spatial distribution. A population clustering method (SAMOVA) and a maximum-di...

watermelon mosaic virus is the most prevalent potyvirus infecting cucurbits in iran. in order to determine the distribution and frequency of the virus, 326 watermelon, melon, cucumber, winter and summer squash samples were collected from 22 villages around urmia during summer 2010 and tested by das-elisa with a polyclonal antibody. ninety four samples were detected as infected by elisa. to dete...

Accepted : August, 2009 The complexity of many virus diseases has led to the development of a large number of approaches for their control. The use of chemical insecticides at large scale has caused serious environmental problems. However, permanent elimination of any significant amount of broad spectrum synthetic pesticide also cannot be adopted. Thus new pesticides which can meet different st...
