A study was made in climate chambers to determine the effect of various temperatures (65°, 75°, 85°, and 95° F.) on symptom expression by cucumber, plantain and banana plants affected by cucumber mosaic virus. Mitigation of symptoms occurred when plantain, banana, and cucumber plants affected with cucumber mosaic virus were kept at 95° F. At 85° F., mitigation of symptoms was less dramatic. Some of the affected plants became necrotic and stunted. At 75° F., severe symptoms of the disease were evident on test plants of the three species. At 65° F., musaceous plants developed symptoms as severe as those observed in the highlands during the cool winter months. Cucumber plants developed severe mottling symptoms at this same temperature.

Satellite RNAs (satRNAs) are associated with Cucumber mosaic virus (CMV) in tomato, most often causing severe epidemics of necrotic plants, and not associated with specific host symptoms. Laboratory studies on virus transmission by the aphid vector Aphis gossypii were performed to better understand the dynamics of field populations of CMV. The presence of satRNAs correlated with lower concentrations of virus in infected plants and with a decrease in the efficiency of transmission from satRNA-infected plants. Both the concentration of virus in CMV-infected tomato and the efficiency of transmission varied more extensively with nonnecrogenic satRNAs than with necrogenic satRNAs. A negative effect of satRNAs on virus accumulation can account, in part, for a decrease in the field transmission and recovery of CMV + satRNAs. Aphids behaved differently and probed less readily on plants infected with CMV + necrogenic satRNAs compared with plants containing non-necrogenic satRNAs. Aphid-mediated satRNA-free CMV infections were observed in test plants when aphids were fed on source plants containing CMV + nonnecrogenic satRNA; no comparable satRNA-free test plants occurred when aphids were fed on source plants containing necrogenic satRNAs. These results indicate that factors associated with transmission can be a determinant in the evolution of natural populations of CMV and its satRNA.

From <i>Anemone coronaria</i> cucumber mosaic virus (<i>Cucumis virus 1 Smith</i>) was isolated. It caused a general chlorosis, reduction of leaves blades and of the whole plants. 66 species of test plants were inoculated with the sap from infected cucumber plants. 33 of these were infected systemically and 11 only locally. Among 22 noninfected plants was <i>Anemone coronaria</i> which indicated as it was experimentally proved, that this species is infected only by the aphids – <i>Myzus persicae</i> Sulz.

Biological Differentiation

The symptoms and host ranges of 16 strains of cucumber mosaic virus (CMV) from both Subgroup I and II were compared on selected pasture and grain legumes. None infected either Arachis hypogea or Glycine max, although 13 other plant species were infected. The observation that success of inoculation varied with the time of year, may limit the usefulness of the biological differentiation of strains. No hosts tested distinguished Subgroup I or II isolates. The distribution of symptoms and virus in Medicago spp. was uneven and the virus was first detected in some cultivars 6-12 weeks after inoculation, indicating that any test for resistance to CMV in these species would have to be prolonged. Most cultivars of lupin tested were severely affected by several strains of CMV, which caused necrosis and death under conditions which excluded other pathogens.

The results of studies involving aphid trapping and natural virus infection of test plants showed that A. gossypii played an important part in cucumber and gherkin infection by CMV, which occurred most frequently in August. However, only a small percentage of any of the aphids found was responsible for virus transmission. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Symptomatic Tissue

Garlic mustard (Alliaria officinalis) is a common weed species associated with woodland borders, hedge rows, and suburban gardens. Garlic mustard plants expressing foliar symptoms of leaf mosaic and vein banding were collected from Franklin and Cuyahoga counties in Ohio. Analysis of symptomatic tissue using viral-associated double-stranded RNA (dsRNA) analysis on 5% polyacrylamide gels and stained with ethidium bromide resulted in the production of a banding profile (four dsRNA bands with molecular weights of 2.6, 2.0, 1.5, and 0.7 × 106 daltons) similar to that of Cucumber mosaic virus (CMV) (1). Symptomatic tissue suspected of being infected with CMV was analyzed with an indirect enzyme-linked immunosorbent assay (iELISA) employing commercially produced antiserum (Agdia Inc.) against the common strain of CMV antiserum confirmed the presence of CMV. Nonsymptomatic tissue reacted negatively to CMV. This is the first report of CMV in garlic mustard in Ohio. Due to the extensive range of this weed and the wide host range of CMV in ornamental and food-plant species, garlic mustard could serve as an alternate host for CMV in many commercially important plant species.

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.
