Particle bombardment drastically increases the infectivity of cloned DNA of zucchini yellow mosaic potyvirus

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

Engineering zucchini yellow mosaic potyvirus as a non-pathogenic vector for expression of heterologous proteins in cucurbits.

Plant virus vectors provide an attractive biotechnological tool for the transient expression of foreign genes in whole plants. As yet there has been no use of recombinant viruses for the improvement of commercial crops. This is mainly because the viruses used to create vectors usually cause significant yield loss and can be transmitted in the field. A novel attenuated zucchini yellow mosaic pot...

Genes for resistance to zucchini yellow mosaic in tropical pumpkin.

Four cultigens of Cucurbita moschata resistant to zucchini yellow mosaic virus were crossed with the susceptible 'Waltham Butternut' and with each other in order to clarify the mode of inheritance of resistance and relationships among the genes involved. Five loci were segregating, with genes for resistance Zym-0 and Zym-4 carried by 'Nigerian Local' and one of them also carried by 'Nicklow's D...

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...

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...
