Resistance to the Emerging Moroccan Watermelon Mosaic Virus in Squash

Study of resistance to cucumber mosaic virus watermelon mosaic virus and zucchini yellow mosaic virus in melon cultivars

Inheritance of resistance to zucchini yellow mosaic virus and watermelon mosaic virus in watermelon.

High resistance to zucchini yellow mosaic virus-China strain (ZYMV-CH) and moderate resistance to watermelon mosaic virus (WMV) were found in a selection of PI 595203 (Citrullus lanatus var. lanatus), an Egusi type originally collected in Nigeria. Mixed inoculations showed primarily that these two viruses have no cross-protection. This fact may explain the high frequency of mixed infection ofte...

Barriers to gene flow between emerging populations of Watermelon mosaic virus in Southeastern France.

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...

First Complete Genome Sequence of a Watermelon Mosaic Virus Isolated from Watermelon in the United States.

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.

Squash Mosaic Virus in Muskmelon Seed Distributed Commercially in Ontario

The of a virus similar to the ringspot strain of squash mosaic virus is reported in muskmelon (gxmnis melo L.). The virus was found in seedlings grown in the greenhouse from seed of the cultivar Iroquois obtained commercially in Canada. Evidence of transmission of the virus through the roots of neighboring plants was obtained in a greenhouse test. occurrence
