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.

Subgroup Ii

During a survey in January 2006 near Salem in Tamil Nadu (south India), Cucumber mosaic virus was observed infecting tomatoes with an incidence of more than 70%. Plants exhibiting severe mosaic, leaf puckering, and stunted growth were collected, and the virus was identified using diagnostic hosts, evaluation of physical properties of the virus, compound enzyme-linked immunosorbent assay (ELISA) (ELISA Lab, Washington State University, Prosser), reverse-transcription polymerase chain reaction (RT-PCR), and restriction fragment length polymorphism analysis (DSMZ, S. Winter, Germany). To determine the specific CMV subgroup, total RNA was extracted from 50 infected leaf samples using the RNeasy plant RNA isolation kit (Qiagen, Hilden, Germany) and tested for the presence of the complete CMV coat protein gene using specific primers as described by Rizos et al. (1). A fragment of the coat protein was amplified and subsequently digested with MspI to reveal a pattern of two fragments (336 and 538 bp), indicating CMV subgroup II. No evidence of mixed infection with CMV subgroup I was obtained when CMV isolates representing subgroups I (PV-0419) and II (PV-0420), available at the DSMZ Plant Virus Collection, were used as controls. Only CMV subgroup I has been found to predominantly infect tomato in the Indian subcontinent, although Verma et al. (2) identified CMV subgroup II infecting Pelargonium spp., an ornamental plant. To our knowledge, this is the first report of CMV subgroup II infecting tomato crops in India. References: (1) H. Rizos et al. J. Gen. Virol. 73:2099, 1992. (2) N. Verma et al. J. Biol.

Eryngium amethystinum (amethyst sea holly) is a herbaceous plant commonly grown as an ornamental perennial in U.S.D.A. hardiness zones 3 to 8. The plant thrives in dry areas with infertile soils and the flowers are often used in dried floral arrangements. Canna spp. (Canna), soft perennials (U.S.D.A. zone 9 and above), are becoming popular flowering plants because of their bright flowers and spectacular foliage. There are a variety of species that fall under the heading Canna spp., of which the most popular are C. glauca, C. indica, C. edulis, and C. iridiflora. Hybrids of Aquilegia (garden columbine), a hardy perennial (U.S.D.A. zones 3 to 9), flower in late spring through early summer. The genus is made up of a wide variety of cultivars. E. amethystinum exhibiting severe mosaic, yellowing, and stunting, along with Canna plants exhibiting severe stunting, chlorotic and distorted foliage, and mosaic, and garden columbine plants exhibiting stunting, leaf curl, chlorosis, and mosaic, collected from commercial plantings throughout the central Ohio area, were analyzed for the presence of virus infection with viral-associated, double-stranded RNA (dsRNA) analysis. dsRNA analysis resulted in a banding profile typical of that seen with members of the cucumovirus family of plant viruses. Plants positive for cucumovurus-like dsRNA were tested with a direct antibody sandwich enzyme-linked immunosorbent assay (ELISA). ELISA results confirmed the presence of cucumber mosaic virus (CMV) in all symptomatic plants tested. No evidence of dsRNA or CMV was found in any of the asymptomatic plants tested. Because all of these hosts are common in the perennial garden, they could serve as a reservoir host of CMV for other plants in the garden. This is the first report of CMV in E. amethystinum, Canna spp., and Aquilegia hybrids in Ohio.

Lobelia (Lobelia erinus L.) is a common herbaceous annual used in flower beds and hanging baskets. The plant blooms from early to late summer. In the summer of 2000, Lobelia plants expressing virus-like symptoms were collected from a greenhouse-based production site in Ohio. Affected plants expressed a mild leaf mosaic and stunting. Viral-associated dsRNA was isolated from 7 g of symptomatic leaf tissue (1). Four dsRNAs were observed at 3.9, 3.0, 2.25, and 1.05 kb indicating the presence of a Cucumovirus. A fifth dsRNA at 0.75 kb also was observed, consistent with the presence of a satellite RNA. Enzyme-linked immunosorbent assay (ELISA) analysis (Agdia, Inc., Elkhart, IN) of symptomatic Lobelia tissue confirmed the presence of Cucumber mosaic virus (CMV). A (S)CARNA-5 (-) cDNA clone (American Type Culture Collection #45124) was labeled with digoxygenin (DIG) as per the manufacturer's instructions (Genius II DIG-DNA Labeling Kit, Boehringer Mannheim) and used as a diagnostic probe to detect this satellite RNA. Northern hybridization confirmed the identity of the satellite RNA (2). This is the first report of any satellite RNA associated with a virus infection in Lobelia and the first report of CMV in this host in Ohio. References: (1) J. R. Fisher and S. G. P. Nameth.

Blephilia hirsuta (Pursh) Benth. var. hirsuta, an ornamental plant known as hairy pagoda or hairy wood mint (Lamiaceae), is native to eastern North America and is listed as an endangered species or a species of special concern in several northeastern states ( http://www.ct.gov/dep/cwp/view.asp?a=2702&q=323482&depNav_GID=1628 and http://www.mass.gov/dfwele/dfw/nhesp/species_info/mesa_list/mesa_list.htm ). B. hirsuta, grown as an ornamental on the University of Arkansas campus in Fayetteville, exhibited mottling symptoms indicative of viral infection. Double-stranded RNA extractions (3) yielded four bands of approximately 3.2, 2.9, 2.2, and 0.9 kb, a pattern identical to that of Cucumber mosaic virus (CMV [2]). Nicotiana benthamiana and Chenopodium quinoa seedlings were mechanically inoculated with sap from symptomatic tissue. N. benthamiana inoculated plants were stunted and developed systemic mosaic and C. quinoa inoculated plants developed local lesions, whereas mock inoculated plants remained symptomless. Dot-blot and indirect ELISA using antisera against CMV (developed by H. A Scott) gave strong reactions when testing symptomatic tissue from B. hirusta, N. benthamiana, and C. quinoa compared with no reaction for symptomless plants. Total nucleic acid extractions (4) from symptomatic tissue was subjected to reverse transcription-PCR using Cucumovirus degenerate primers (1). An amplicon of approximately 940 bases was obtained and sequenced. The sequence, deposited in GenBank under Accession No. GU453918, confirmed the results of the immunological assays that B. hirsuta was infected with CMV. The nucleotide identities between the B. hirsuta isolate and those of the Fny CMV group exceeded 98%. To our knowledge, this is the first report of CMV infecting B. hirsuta, not only in North America, but globally. This finding has major implications for the ornamental industry and the viability of the endangered species. Given the wide range of CMV, B. hirsuta may act as a reservoir for the virus and facilitate transmission to ornamentals and other plants. In addition, the virus may reduce host fitness and undermine the efforts to preserve the species in areas that is threatened. References: (1) S. K. Choi et al. J. Virol. Methods 83:67, 1999. (2) I.

General Appearance

Adiantum pedatum (maidenhair fern) is a fern commonly used in landscapes and interiorscapes for its attractive foliage. A. pedatum is quite hardy and under conditions of good soil fertility it can become highly intrusive if left unchecked. Maidenhair fern showing symptoms associated with possible virus infection were collected from the Chadwick Arboretum on the campus of The Ohio State University, Columbus. The leaves of the affected plants were slightly malformed such that the pinnules were arranged irregularly at the pinna. The sequence of the pinnae on the rachis and the general appearance of the rachis were distorted. Overall, the symptoms observed were not as severe as those described by Nienhaus et al. on other species of ferns (1). Viral-associated double-stranded RNA (dsRNA) analysis was used to analyze tissue from symptomatic and asymptomatic plants for evidence of virus infection. Results of dsRNA analysis gave evidence of a possible cucumovirus. There was no evidence of dsRNA in the asymptomatic tissue. Symptomatic tissue was subsequently tested for cucumber mosaic virus (CMV) with a direct antibody sandwich, enzyme-linked immunosorbent assay (ELISA). ELISA results were positive for CMV in symptomatic tissue and negative for CMV in asymptomatic tissue. This is the first report of a virus associated with a disease in A. pedatum. Reference: (1) F.

Cucumber mosaic virus (CMV) is a cosmopolitan virus which may also have small satellite RNAs (satRNA) associated with it affecting symptom development. Vinca minor (periwinkle) plants exhibiting subtle mosaic symptoms tested positive for CMV by enzyme linked immunosorbent assay (ELISA). Double-stranded ribonucleic acid (dsRNA) analysis of CMV-Vinca field isolates in Nicotiana tabacum ‘Glurk’ suggested two sizes of putative satRNA associated with CMV. Immunocapture RT-PCR, cloning, and sequencing of the movement protein, coat protein, and satRNAs demonstrated serogroup 1A and serogroup 2 CMV helper strains and three distinct classes of satRNAs of four sizes. Further, two classes of satRNAs could be distinguished by their necrosis domains. Previously CMV was reported in V. minor in New Jersey. This is the first report of CMV in V. minor in Ohio and the first report of satRNA associated with CMV in V. minor in the United States. Accepted for publication 1 February 2012.

Local Lesions

Lavandula angustifolia Mill. (synonym Lavandula officinalis Chaix), belonging to the Lamiaceae family, is a plant that is widespread in Mediterranean countries. The species is widely grown as an ornamental crop in Poland. Currently, only Alfalfa mosaic virus (AMV) is known to infect L. latifolia × L. officinalis in Italy (3). In the spring of 2005, we observed yellow mottling, leaf deformation, and growth reduction of L. angustifolia plants from the Agricultural Academy of Kraków collection of medicinal herbs and spices. Mechanical inoculation of a range of indicator plant species, Chenopodium quinoa, Cucumis sativus, Datura strammonium, Nicotiana glutinosa, N. tabacum cv. Xanthi, Lycopersicon esculentum, and Spinacia oleracea, with sap from symptomatic L. angustifolia plants resulted in symptoms typical of Cucumber mosaic virus (CMV). Chlorotic local lesions and systemic mosaic were observed after a few days on the tested plant species. However, local lesions did not develop on inoculated C. sativus cotyledons. A lack of systemic infection on Chenopodium quinoa excluded infection by AMV. The sap from symptomatic N. tabacum cv. Xanthi leaves contained spherical virus particles of 29 nm in diameter when examined with electron microscopy. Symptomatic N. tabacum cv. Xanthi leaves were positive for CMV in a double-antibody-ELISA using commercial CMV antiserum (Loewe Biochemica GmbH, Sauerlach, Germany). Total RNA was extracted from infected N. tabacum cv. Xanthi plants by the phenolchloroform method. Reverse transcription-PCR was carried out using specific primers CMVF 5′-CCCACAGGTAGAATCAAAT-3′ and CMVR 5′-ATGGACAAATCTGAATCAAC-3′ (1). The 367-bp amplicon representing a portion of the coat protein gene located in RNA3 was cloned into pGEM-T Easy Vector (Promega, Madison, WI) and two clones were sequenced. The fragment sequence (Accession No. EU303304) was compared with homologous sequences of CMV isolates from the GenBank database. Multiple sequence alignment was performed by using Mega 4 (Center for Evolutionary Functional Genomics, Tempe, AZ) (4) and revealed 99% nucleotide and amino acid identity between the Polish isolate of CMV-PL and the RT67 (subgroup II) isolate from the Netherlands (2) To our knowledge, this is the first report on the occurrence of CMV on Lavandula angustifolia Mill. in Poland or worldwide.

Rattlesnake master (Eryngium yuccifolium) is a wildflower that is native to Ohio. In recent years, native wildflowers have become very popular with home gardeners, and conservationists have begun to reestablish these plants in their native ranges. As native perennial wildflowers become more common, it is important to determine if they might serve as possible perennial reservoirs of viruses. A plot of 20 species native to Ohio was established on the Waterman Agricultural and Natural Resources Laboratory, The Ohio State University, Columbus, Ohio. In the summers of 1999 and 2001, random samples were collected from established plantings. Some sampled plants did not show symptoms of virus infection; however, all samples of E. yuccifolium appeared chlorotic, slightly mottled, and stunted. Using double-stranded RNA (dsRNA) analysis (1), these plants were assayed for viral infection. dsRNA profiles obtained from symptomatic E. yuccifolium resembled that of Cucumber mosaic virus (CMV). These results were confirmed with an enzyme-linked immunosorbent assay (ELISA; Agdia Inc., Elkhart, IN) for CMV. dsRNA-containing samples of E. yuccifolium produced ELISA absorbance values (A405) of 0.231 to 0.713 when compared with the negative control. All 14 samples of E. yuccifolium tested positive for CMV. To our knowledge, this is the first report of CMV in E. yuccifolium, which should serve as the basis for a more extensive survey, since CMV can potentially infect a wide variety of ornamental and nonornamental hosts.

Desert rose (Adenium obesum (Forssk.) Roem. & Schult, family Apocynaceae) is native to southeastern Africa, and is a perennial potted ornamental with colorful flowers that are popular in Taiwan. Symptoms of mosaic and chlorotic ringspots and line patterns on leaves were observed in July 2010, on all eight plants in a private garden in Potzu, Chiayi, Taiwan. Spherical virus particles with a diameter of approximately 28 nm were observed in crude sap prepared from symptomatic leaves. Virus culture was established by successive local lesion isolation in Chenopodium quinoa and was maintained in the systemic host Nicotiana tabacum van Hicks. The virus was mechanically transmissible to indicator plants and induced symptoms similar to those incited by Cucumber mosaic virus (CMV). Observed symptoms included local lesions on inoculated leaves of C. amaranticolor and systemic mosaic in Cucumis sativus, Lycopersicon esculentum, N. benthamiana, N. glutinosa, and N. rustica. On N. tabacum, necrotic ringspots developed on inoculated leaves followed by systemic mosaic. Serological tests using ELISA assays and western blotting indicated that the virus reacted positively to a rabbit antiserum prepared to CMV (4). Amplicons of an expected size (1.1 kb) were obtained in reverse transcription-PCR with primers specific to the 3′-half of CMV RNA 3 (3) using total RNA extracted from infected desert rose and N. tabacum. The amplified cDNA fragment was cloned and sequenced (GenBank Accession No. AB667971). Nucleotide sequences of the coat protein open reading frame (CP ORF) (657 nt) had 92 to 96% and 76 to 77% sequence identity to those of CMV in subgroups I (GenBank Accession Nos. NC_001440, D00385, M57602, D28780, and AB008777) and II (GenBank Accession Nos. L15336, AF127976, AF198103, and M21464), respectively. Desert roses infected by Tomato spotted wilt virus (TSWV) (1) and CMV (2) have been reported previously. In spite of the plants showing mosaic symptoms similar to that caused by CMV (2) and chlorotic ringspots and line patterns caused by TSWV (1), only CMV was detected in and isolated from these infected desert roses. However, the possibility of mixed infection of CMV and other viruses were not excluded in this research. To our knowledge, this is the first report of CMV infection in desert rose plants occurring in Taiwan. References: (1) S. Adkins and C. A. Baker. Plant Dis. 89:526, 2005. (2) C. A. Baker et al.
