Yellowing Disease in Zucchini Squash Produced by Mixed Infections of Cucurbit yellow stunting disorder virus and Cucumber vein yellowing virus

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

Biological and Molecular Characterization of a Korean Isolate of Cucurbit aphid-borne yellows virus Infecting Cucumis Species in Korea

Surveys of yellowing viruses in plastic tunnels and in open field crops of melon (Cucumis melo cultivar catalupo), oriental melon (C. melo cultivar oriental melon), and cucumber (C. sativus) were carried out in two melon-growing areas in 2014, Korea. Severe yellowing symptoms on older leaves of melon and chlorotic spots on younger leaves of melon were observed in the plastic tunnels. The sympto...

Geographic distribution and phylogenetic analysis of cucurbit yellow stunting disorder virus in Iran.

Cucurbit yellow stunting disorder virus (CYSDV) is a destructive virus of cucurbits in Iran. During 2008-2012 growing seasons a total of 366 cucurbit samples including melon, cucumber, snakemelon and squash with typical symptoms of CYSDV infection were collected from ten Provinces in Iran. They were screened by ELISA and the infectivity of ELISA-positive samples was confirmed by RT-PCR. The res...

Genetic diversity of a natural population of Cucurbit yellow stunting disorder virus.

An analysis of nucleotide sequences in five coding and one non-coding genomic regions of 35 Cucurbit yellow stunting disorder virus (CYSDV) isolates collected on a local scale over an 8 year period is reported here. In total, 2277 nt were sequenced for each isolate, representing about 13 % of the complete virus genome. Mean nucleotide diversity for the whole population in synonymous positions i...

The presence of Cucurbit yellow stunting disorder Crinivirus (CYSDV) was confirmed by the following tests: transmission by Bemisia tabaci to cucumber, mel- on and squash but not to lettuce or to Physalis floridana; presence in infected plants of two dsRNAs

Virus diseases are the major cause of economic losses in commercial cucurbit production in Lebanon. Besides mosaic inducing viruses, which have been noted for several years, greenhouse-grown cucumber and melon were often observed with severe yellowing symptoms that started as interveinal mottle on the older leaves and developed into severe yellowing symptoms as the leaves became older. The inci...
