Tropical Conditions

Zucchini yellow mosaic virus (ZYMV) infection causes heavy losses in cucurbit crops grown in the Mediterranean, Central Europe, the United States, and Mexico. Recently, ZYMV was found affecting muskmelon (Cucumis melo L.) in Colima, Mexico. An experiment was carried out under dry tropical conditions with the objectives: 1) to determine the effect of ZYMV on flowering and yield of muskmelon cv. Primo, and 2) to evaluate its transmission by some aphid species. Perfect and staminate flowers were significantly reduced when ZYMV was inoculated during vegetative growth, flowering, and fruit set. ZYMV affected yield when it was inoculated from vegetative growth to flowering and fruit set. In plants inoculated during vegetative growth the yield was null, while those inoculated at early flowering and fruit set the yield was reduced by 80% and 49%, respectively. The yield was not affected when ZYMV was inoculated on fruit growth. The aphid Myzus persicae, Aphis gossypii, A. spiraecola, and Uroleucon ambrosia-transmited ZYMV from Cucurbita pepo to Cucumis melo; but Aphis nert, did not.

Breeding Lines

In an effort to develop bottle gourd (Lagenaria siceraria) as a widely adapted rootstock for watermelon grafting, we sought to identify lines with broad resistance to several cucurbit viruses that are economically important in the United States. Preliminary analysis under greenhouse conditions indicated that the currently available commercial watermelon rootstocks were either highly susceptible or somewhat tolerant to one or more viruses. However, in greenhouse screening, several breeding lines of bottle gourd displayed broad-spectrum resistance to four viruses tested, including Zucchini yellow mosaic virus, Watermelon mosaic virus (WMV), Papaya ringspot virus watermelon strain (PRSV-W), and Squash vein yellowing virus. Resistance to PRSV-W and WMV was confirmed through field trials in two consecutive years at two different locations in South Carolina. Two breeding lines (USVL#1-8 and USVL#5-5) with broad-spectrum virus resistance could be useful materials for watermelon rootstock development.

Relationship Of

We have studied the relationship of resistance to watermelon mosaic virus (WMV), zucchini yellow mosaic virus (ZYMV), papaya ringspot virus (PRSV), and powdery mildew (PM) in melon (Cucumis melo). We have confirmed monogenic dominant inheritance of these four resistances and report that PI414723-4S3, which was initially selected as a source of ZYMR, is also a source of dominant monogenic resistance to PRSV. Further, we observed departure from independent assortment for resistance to WMV and ZYMV in a study of 73 (UC Top Mark × PI414723-4S3) F3 families (χ2 = 39.87 significant at both 0.01 and 0.05 levels), indicating linkage between Wmv and Zym. The map distance between these resistance genes calculated from the number of recombinant families (RF% = 9.58) was 10.5 cM. Compari-sons among WMV, PM, ZYMV-PM, PRSV-PM, ZYMV-PRSV, and WMV-PRSV of 48 (TM × PI414723-4S3) F3 families, which were screened with all four pathogens, showed no consistent cosegregation.

Negative Effect

The performance of snake melon [Cucumis melo var. flexuosus (L.)] in organic farming was studied under high biotic and salt stress conditions. Soilborne diseases (mainly caused by Macrophomina phaseolina and Neocosmospora falciformis), combined with virus incidence [Watermelon mosaic virus (WMV), Zucchini yellow mosaic virus (ZYMV), and Tomato leaf curl New Delhi virus (ToLCNDV)] and Podosphaera xanthii attacks, reduced yield by more than 50%. Snake melon susceptibility to M. phaseolina and Monosporascus cannonballus was proved in pathogenicity tests, while it showed some degree of resistance to Neocosmospora keratoplastica and N. falciformis. On the contrary, salt stress had a minor impact, although a synergic effect was detected: yield losses caused by biotic stress increased dramatically when combined with salt stress. Under biotic stress, grafting onto the melon F1Pat81 and wild Cucumis rootstocks consistently reduced plant mortality in different agroecological conditions, with a better performance compared to classic Cucurbita commercial hybrids. Yield was even improved under saline conditions in grafted plants. A negative effect was detected, though, on consumer acceptability, especially with the use of Cucurbita rootstocks. Cucumis F1Pat81 rootstock minimized this side effect, which was probably related to changes in the profile of sugars, acids, and volatiles. Grafting affected sugars and organic acid contents, with this effect being more accentuated with the use of Cucurbita rootstocks than with Cucumis. In fact, the latter had a higher impact on the volatile organic compound profile than on sugar and acid profile, which may have resulted in a lower effect on consumer perception. The use of Cucumis rootstocks seems to be a strategy to enable organic farming production of snake melon targeted to high-quality markets in order to promote the cultivation of this neglected crop.

First Report

The aphid-transmitted Zucchini yellow mosaic virus (ZYMV; genus Potyvirus, family Potyviridae) has been reported to cause severe epidemics and yield losses in cucurbit crops worldwide (1). In Africa, ZYMV has been detected in Algeria, Egypt, Madagascar, Mauritius, Mayotte, Morocco, Nigeria, Reunion, South Africa, Sudan, Swaziland, and Tunisia (1). In April 2009, leaf yellowing, mosaic, crinkling, and curling were common on cucurbit plants in fields in Mali. Symptomatic leaf samples were collected from five cucumber (Cucumis sativus) plants in Kati, two watermelon (Citrullus lanatus) plants in Samanko, and one weedy melon (Cucumis sp.) plant in Baguineda. All samples tested positive for ZYMV and were negative for Cucumber mosaic virus (CMV), Cucumber green mottle mosaic virus (CGMMV), Papaya ringspot virus type W (PRSV-W), Watermelon mosaic virus (WMV), and Watermelon silver mottle virus (WSMoV) by double-antibody sandwich (DAS)-ELISA. They also tested negative for Melon yellow spot virus (MYSV) by indirect ELISA. Antibodies against ZYMV and WMV were obtained from DSMZ, Braunschweig, Germany, and those against CGMMV, MYSV, PRSV-W, and WSMoV were provided by Shyi-Dong Yeh, National Chung Hsing University, Taichung, Taiwan. Six ZYMV ELISA-positive samples (three cucumber, two watermelon, and the weedy melon sample) were also tested by reverse transcription (RT)-PCR using the potyvirus universal primer pair Sprimer1/Oligo(dT) (2). The expected 1.6-kb viral cDNA was amplified from all six samples and each was sequenced. All sequences obtained from cucumber (GenBank Accession Nos. HM005307, HM005308, and HM005309), watermelon (GenBank Accession Nos. HM005311 and HM005312), and weedy melon (GenBank Accession No. HM005310) isolates were 1,684 nucleotides (nt) long excluding the 3′ poly-A tails. They comprised the 3′-terminal of the NIb region (1 to 633 nt), the coat protein region (634 to 1473 nt), and the 3′-untranslated region (1,474 to 1,684 nt). Because the sequences shared high nucleotide identity (98.3 to 99.7%), these isolates were considered to be the same virus species. When the sequences were compared by BLASTn searching in GenBank and analyzed by DNAMAN Sequence Analysis Software (Lynnon Corporation, St-Louis, Pointe-Claire, Quebec, Canada), they were found to have the greatest nucleotide identity (97.4 to 98.0%) with the Connecticut strain of ZYMV (ZYMV-Connecticut; GenBank Accession No. D00692), within a clade of isolates from China, Italy, Japan, and the United States. When assessed separately, their coat protein (97.7 to 98.3% nucleotide and 98.9 to 99.6% amino acid identity) and 3′-untranslated regions (96.7 to 97.2% identity) also had greatest homology with ZYMV-Connecticut. To our knowledge, this is the first report of ZYMV infecting cucurbit plants in Mali. ZYMV should be taken into consideration when breeding cucurbit crops for this region, and managing viral diseases. References: (1) C. Desbiez et al. Plant Pathol. 46:809, 1997. (2) W. S. Tsai et al.
