www.invasivespeeies.org.Newlnitiatives.html) provides a guide for trading partners and alerts them to pests of quarantine concern in the U.S. APHIS activities include an inspection at ports-of-entry, surveys of exotic pests, methods of risk mitigation and eradication programs. APHIS also oversees a post-entry program for vegetatively propagated materials entering the U.S. and a pie-clearance program from specific countries that allows products to enter without additional inspection following importation. The Pest List currently includes seventy viruses but only six of them infect ornamentals. Included are Arabis mosaic virus, Elm mottle virus, Raspberry ringspot virus, Tobacco ring.spot virus (Andean potato calico strain). Tomato b/ackring virus, and Colombian datura virus. During the last two years Raspberry ringspot virus, Tomato blackring virus, and Arabis mosaic virus were detected in samples sent to Agdia, Inc., (http://www.agdia.com). There are 93 genera and families of plants in the prohibited quarantine category in the U.S. regulations. Most are propagated vegetatively. There are very few restrictions on import of seeds. Prohibitions may apply to certain countries or to all countries depending on the risk assessment (United States Department of Agriculture (USDA) Title 7-Code of Federal Regulations-Part 319). Only four genera of cut flowers, including Rhododendron and azaleas, Camellia, Gardenia, Rosa and Svringu vu/guns are required to have written permits issued by the Animal and Plant Health Inspection Service of the USDA for entry into the U.S. Importers must also obtain phytosanitary certificates from the exporting country. The prohibited category includes many genera of nursery stock, plants, roots, bulbs and other plant products. Prohibited does not mean that all the materials classified as prohibited are restricted from entering the country (USDA Title 7-Code of Federal Regulations-Part 3 19). Prohibition is a function of both host and country of origin. Some articles that are intended for propagation may be in a restricted category that allows entry when specific requirements are fullfilled. For example. Chrysanthemum vegetative material can enter the country with a phytosanitary certificate from the nation of origin and a declaration that the greenhouse where the plants were grown was free of white rust based on visual inspection monthly for a period of four months prior to shipment. Imported Dianthus from Great Britian must be accompanied by a phytosanitary certificate and an additional declaration verifying that the propagated material was grown in a greenhouse free of Carnation etched ring virus, Carnation "streak' virus and Carnation "fleck" virus. In addition to the requirements imposed on the exporter, the importer may have to grow designated restricted articles in post-entry quarantine. Imported Chrysanthemum. Crocosmia, Dianthus, Gladiolus, Hibiscus, Hydrangea, Jasminum, Rosa, Syringa and Watsonia must all be grown in a protected environment that meets State regulations and must be perio...

“…This type of vegetative propagation is an efficient way for virus transmission ( Sharma et al, 2005 ; Zhang et al, 2017 ). To date, more than 15 lily-infecting viruses have been reported, including lily symptomless virus (LSV), lily mottle virus (LMoV), cucumber mosaic virus (CMV), plantago asiatica mosaic virus (PlAMV), tulip virus X (TVX), tobacco rattle virus (TRV) ( Jo and Cho, 2018 ), lily yellow mosaic virus (LYMV) ( Li et al, 2017 ), strawberry latent ringspot virus (SLRSV) ( Sharma et al, 2005 ), lily virus X ( Nijo et al, 2018 ), arabis mosaic virus (ArMV) ( Zheng et al, 2003 ), prunus necrotic ringspot virus (PNRSV) ( Han and Liu, 2007 ), lily virus A ( Wylie et al, 2012 ), shallot yellow stripe virus (SYSV) ( Xu et al, 2022 ), tomato ringspot virus (ToRSV) ( Bellardi et al, 2002 ), milk retch dwarf virus (MDV) ( Choi et al, 2019 ), and narcissus mosaic virus (NaMV) ( Bertaccini, 1988 ). Among these viruses, only MDV is a single-stranded DNA virus, and the other 15 viruses are positive-sense RNA viruses.…”

Genetic diversity and phylogenetic characteristics of viruses in lily plants in Beijing

et al. 2023

Lily (Lilium) is an important bulbous perennial herb that is frequently infected by one or more viruses. To investigate the diversity of lily viruses, lilies with virus-like symptoms in Beijing were collected to perform small RNA deep sequencing. Then, the 12 complete and six nearly full-length viral genomes, including six known viruses and two novel viruses were determined. Based on sequence and phylogenetic analyses, two novel viruses were considered to be members of the genera Alphaendornavirus (Endornaviridae) and Polerovirus (Solemoviridae). These two novel viruses were provisionally named lily-associated alphaendornavirus 1 (LaEV-1) and lily-associated polerovirus 1 (LaPV-1). Based on sequence, phylogenetic and recombination analyses, strawberry latent ringspot virus (SLRSV) in the genus Stralarivirus (Secoviridae) was identified for the first time in China, and shown to exhibit the highest nucleotide (nt) diversity among the available full-length SLRSV genome sequences, with the highest identities of 79.5% for RNA1 and 80.9% for RNA2. Interestingly, the protease cofactor region in RNA1 was 752 aa in length, whereas those of the other 27 characterized isolates ranged from 700–719 aa in length. The genome sequences of lily virus A (Potyvirus), lily virus X (Potexvirus), and plantago asiatica mosaic virus (Potexvirus) exhibited varying degrees of sequence diversity at the nucleotide level compared with their corresponding characterized isolates. In addition, plantago asiatica mosaic virus (PlAMV) tended to cluster on a host species-basis. One identified lily mottle virus (Potyvirus) isolate was detected as a recombinant, and which clustered in a different group with four other isolates. Seven identified lily symptomless virus (Carlavirus) isolates, including one recombinant, were clustered into three clades. Our results revealed the genetic diversity of lily-infecting viruses, and sequence insertion, host species and recombination are factors that likely contribute to this diversity. Collectively, our results provide useful information regarding the control of viral disease in lily.

“…Other viruses have been reported for lily in only some countries, e.g., Arabis mosaic virus (ArMV) in the Netherlands (7); Broad bean wilt virus (BBWV), Tomato ringspot virus (ToMRSV), and Lily mild mosaic virus (LMMV) in Korea (22); Citrus tatter leaf virus (CTLV) in Japan (18); Tomato ringspot nepovirus (ToRSV) in Italy (9); Lily virus X (LVX) in the UK (33) and in the Netherlands (24); and Strawberry latent ringspot virus (SLRV) and Tobacco rattle virus in Italy (9,35) and in the Netherlands (7,13).…”

Detection and Frequency of Lily Viruses in Argentina

et al. 2010

View full text Add to dashboard Cite

In a survey of lily growing fields in various regions of Argentina, three viruses, Lily symptomless virus (LSV), Lily mottle virus (LMoV), and Cucumber mosaic virus (CMV), were found in Longiflorum, Asiatic, Oriental, Longiflorum × Asiatic (LA), and Oriental × Trumpet (OT) hybrids. The areas surveyed were between latitude 26° 56′ S and 43° 03′ S, and longitude 65° 21′ W and 71° 29′ W. Virus detection was performed by double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) using polyclonal antiserum. In infected samples, viruses detected in decreasing order were LSV (60.5%), LMoV (51.0%), and CMV (28.7%) present in single or mixed infections. Virus infection varied among tested hybrids from 36.0% (Oriental Montecristo) to 94.7% (Lilium longiflorum Avita) in 2006 and from 38.9% (OT Yelloween) to 82.1% (LO Triumphator) in 2007, with an overall incidence of 64.1 and 70.7% in 2006 and 2007, respectively. A variation in virus incidence among localities was also observed. The highest virus incidence (89.6 and 87.6% in 2006 and 2007, respectively) was observed in Bahía Blanca (38° 44′ S, 62° 16′ W). The lowest virus incidences, detected in Trevellin (43° 03′ S, 71° 29′ W) and in Malargüe (35° 28′ S, 69° 35′ W), were 47.4 and 48.6% in 2006 and 2007, respectively. Moreover, a different distribution of each virus was observed between localities. The high occurrence of viruses infecting lily crops in Argentina could be due to both the use of infected bulbs for propagation and the lack of preventive virus vector control measures.
