Watermelon mosaic virus (WMV) is widespread in cucurbit crops, most commonly occuring in temperate and Mediterranean regions. In Serbia WMV has been detected in single and mixed infections with Zucchini yellow mosaic virus and Cucumber mosaic virus in field-grown pumpkin and squash crops. Among pumpkin-affecting viruses WMV is the most frequent one, both by the number of localities and its incidence at each location. During the growing season of 2009, samples from 583 plants of Cucurbita pepo cvs. Olinka, Belgrade zucchini and Tosca (Zucchini group), as well as from C. maxima and C. moschata showing symptoms of virus infection were collected from 12 commercial fields at eight localities and analyzed by DAS-ELI

Squash or cucurbit (Cucurbita pepo) is one of the famous and important vegetable plants in most world countries. The squash is infected by the critical Zucchini yellow mosaic virus (ZYMV) in Egypt. Though pesticides can protect the plants of pest infections, there are no effective compounds that can be applied as virucides. In this work, the effects of aqueous extracts from Jasmina montana and Artemisia herba-alba on ZYMV infection in the squash plants were examined. In addition, SDS-PAGE protein patterns and enzyme activities were evaluated and induction of resistance by plant elicitors against ZYMV was studied The results observed that using of the aqueous extracts from A. herba-alba or J. montana extracts prior to ZYMV inoculation recorded 100% inhibition of virus infection. Also, complete inhibition was obtained by treatment of A. herba-alba extract with the virus inoculum led to destroy the virus particles due to presence of the effective compounds (terpens, phenolics and the essential oils) in the plant extract. SDS-PAGE protein profiles and enzyme activities were studied in treated and untreated plants. Genomic DNA variation was studied using random amplified polymorphic DNA (RAPD) and Inter-simple sequence repeat (ISSR) loci. The alterations in RAPD and ISSR assays of representative squash plants can be applied to comprehend of induced systemic resistance. These inducers stimulated resistance in the squash plants. Therefore, elicitors should be taken into consideration in the breeding programs for ZYMV control.
