Characterization of different isolates of Zucchini yellow mosaic virus from cucurbits in Saudi Arabia

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

characterization of the zucchini yellow mosaic virus from squash in tehran province

zucchini yellow mosaic virus (zymv) is a potyvirus with a worldwide distribution. this virus causes serious economic losses in iran in many cucurbits. during 2002-2003, sam-ples were collected from squash fields in tehran province. five isolates (z1, z2, z3, z4 and z5) were inoculated on 27 species of cucurbitaceae, chenopodiaceae, amarantha-ceae,solanacae, leguminosae and ranunculaceae. chenop...

Establishment of a Simple and Rapid Gene Delivery System for Cucurbits by Using Engineered of Zucchini yellow mosaic virus.

The infectious full-length cDNA clone of zucchini yellow mosaic virus (ZYMV) isolate PA (pZYMV-PA), which was isolated from pumpkin, was constructed by utilizing viral transcription and processing signals to produce infectious in vivo transcripts. Simple rub-inoculation of plasmid DNAs of pZYMV-PA was successful to cause infection of zucchini plants (Cucurbita pepo L.). We further engineered th...

Nucleotide sequences of the coat protein genes of two Japanese zucchini yellow mosaic virus isolates.

The nucleotide (nt) sequences of the coat protein (CP) genes of two Japanese zucchini yellow mosaic virus (ZYMV) isolates (ZYMV-169 and ZYMV-M) were determined. The CP genes of both isolates were 837 nt long and encoded 279 amino acids (aa). The nt and deduced aa sequence similarities between the two isolates were 92% and 94.6%, respectively. The deduced aa sequences of CPs of the Japanese isol...

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...
