Host Reaction of Watermelon mosaic virus Isolates Infecting Melon from Different Geographical Origins in Xinjiang of China

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

Low genetic variation between isolates of Citrus leaf blotch virus from different host species and of different geographical origins.

The population structure and genetic diversity of Citrus leaf blotch virus (CLBV) were estimated by single-strand conformation polymorphism and nucleotide sequence analyses of two genomic regions located within the replicase (R) and the coat protein (C) genes. Analysis of 30 cDNA clones of each genomic region from two CLBV isolates showed that both isolates contained a predominant haplotype and...

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...

Inhibitory Effect of Watermelon Mosaic Virus on Meloidogyne javanica (Treub) Chitwood Infecting Cucurbita pepo L.

Interactions between root-knot nematodes and viruses were recently reviewed by Taylor (4). Compared to virus-free cowpea (vigna sinensis Endl.), cowpea mosaic virus-infected plants formed fewer galls on roots in response to infection by Meloidogyne incognita (Kofoid and White) Chitwood (2). On the other hand, tobacco plants (Nicotiana tabacum L.) infected with tobacco ringspot virus (TRSV) and ...
