ABSTRACT Mixed infections in cucurbits are frequently observed in natural conditions between viruses from the Potyvirus genus and Cucumber mosaic virus (CMV), which significantly decreases productivity. The objectives of the present study was to compare the host range of PRSV-W, WMV, and ZYMV isolates and evaluate the effects of mixed infections with CMV in zucchini plants (Cucurbita pepo L.). Host range studies comprising 23 plant species confirmed some similarities and biological differences among the isolates of PRSV-W, ZYMV, and WMV. RT-PCR confirmed the amplification of DNA fragments of the PRSV-W, WMV, and ZYMV coat protein gene (cp) and cytoplasm inclusion gene (ci). The virus interaction studies in zucchini Caserta plants indicated synergistic interactions, particularly among species from the Potyvirus genus, and some CMV interference with some virus combinations.

A virus (BVBMV) capable of inciting mild mosaic and vein-banding symptoms on various hosts was isolated from field beans (Phaseolus vulgaris L.) growing in experimental plots. The causal agent was transmitted by mechanical means as well as via aphids. The results of transmissibility, serology, host range and physical property studies indicate that the virus is a strain, possibly a new one, of the common cucumber mosaic virus (CMV) complex.

Cucumber mosaic virus (CMV) has a reported host range of 750 to 1,200 species (2,3) that includes weeds, wild plants, crops, and ornamentals. Two new CMV hosts were recently identified in Florida. In July 2011, leaves of Odontonema cuspidatum (firespike), a member of the Acanthaceae, with virus-like symptoms were sent to FDACS-DPI. Firespike is an ornamental shrub native to Mexico with evergreen ovate leaves tapering to a pointed tip. Leaf symptoms included severe leaf distortion with some subtle yellowing or mosaic on younger leaves. Pink-red crystals were seen in leaf strips stained with the nucleic acid stain Azure A, indicating a viral infection. In January 2012, leaves of Psychotria punctata (dotted wild coffee), a member of the Rubiaceae, with virus-like symptoms were sent to FDACS-DPI. Dotted wild coffee is a small exotic tropical tree found in south Florida with many tiny leaf nodules inhabited by endosymbiotic bacteria. In addition to the nodules, these leaves had many large dark green ringspots surrounded with a yellow halo. Both samples were positive for CMV when tested with ImmunoStrips and/or by conventional ELISA using CMV antiserum (Agdia, Elkhart, IN). To confirm CMV infection, reverse transcriptase (RT)-PCR on total RNA from a leaf sample of each plant species was used with previously published cucumovirus primers (1). An expected ~940 bp product was amplified from each sample and cloned into pGEM-T (Promega, Madison, WI). Ten clones from each plant species were sequenced in both directions. After removal of primer sequences, the 906 bp products were 96.3% identical with each other and showed 96.8 to 98.9% nucleotide identity with CMV sequences from Hungary, the United States, and Austria (GenBank Accession Nos. AF517802, U20668, and HQ916354, respectively). Identification of CMV infection in these two species expands the known host range and therefore the reservoir of this plant virus. This has implications for the ornamental industry in general and Florida farmers in particular. References: (1) S. K. Choi et al. J. Virol. Methods 83:67, 1999. (2) E. J. Sikora.

In order to identify the cause of virus disease-like symptoms developed naturally in Summer cosmos (Cosmos sulphureus) plants at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur campus, a study was conducted during March 2004 to August 2005. The natural symptoms in Summer cosmos were consisted of mosaic, yellowing, shoe-string and leaf curling along with severe stunting of the infected plants. The ailments were found to be sap transmissible. Gomphrena globosa and Chenopodium amaranticolor were found to be good local lesion hosts producing chlorotic local lesion in the inoculated plants. The virus isolates obtained from the infected G. globosa plant had wide host range including Amaranthaceae, Chenopodiaceae, Compositae, Cucurbitaceae, Ligominosae and Solanaceae. The dilution end point, thermal inactivation point and longevity in vitro were determined as 10-6, 65°C and 10 days, respectively. The host range test, dilution end point, thermal inactivation point and longevity in vitro suggested that the virus was identical to Cucumber mosaic virus (CMV). Double Antibody Sandwich Enzyme-Linked Immuno-Sorbent Assay (DAS-ELISA) detected the virus as CMV. The results of the study revealed that the virus disease-like symptoms naturally manifested in summer cosmos plants was identified as CMV. Key words: Summer cosmos, CMV, virus identification.

1. A virus causing mottle and blistering in leaves of Cucumis melo var. Smith Perfect was isolated from an experimental planting at Río Piedras, P.R., in 1958. Its host range, dilution end-point, thermal inactivation, resistance to freezing, and serological similarity with a severe strain of squash-mosaic virus from Wisconsin (SSV) indicated that it belonged in the squash-mosaic virus group. 2. The studies reported above, as well as tests performed on samples from commercial and experimental cucurbit plantings in Puerto Rico during 1960-62, show that at least three cucurbit viruses are present in Puerto Rico. These are: Cucumber-mosaic virus, squash-mosaic virus, and watermelon-mosaic virus.
