“…However, given the low rate of seed transmission of LigMV in our study (0.7%), it is plausible that Baur did not observe any seed transmission events (he observed only 29 seedlings) even it would have been the same virus. The second author to report a viral mosaic in Ligustrum was Schmelzer (1963), who noted that it might be the same as Baur's viral disease. The disease symptoms such as yellowish/white leaf blotches that he described are similar to those observed here with LigMV (Figures 1A-C).…”

“…Privet (Ligustrum vulgare L., family Oleaceae) is a wild shrub growing in forest edges and a very common plant in natural ecosystems of Switzerland and other European countries, which is also often used for ornamental and hedgerow purposes. Viral disease symptoms on privet were already reported at the beginning of the last century in Germany (Baur, 1906;Schmelzer, 1963). Erwin Baur (1875Baur ( -1933, considered as one of the fathers of plant virology, studied in his pioneer works "infektiöse Chlorose" (infectious chlorosis) on different plants, including privet, and showed that viruses are the causal agents (Baur, 1904(Baur, , 1906(Baur, , 1908.…”

“…The last sentence of Baur's work from 1908 was the following: "Die nächste Aufgabe wird es jetzt sein, den rätselhaften Infektionstoff einigermassen zu isolieren" (The next task will now be to isolate the mysterious infection substance). Since that time, privet and other Ligustrum species were shown to be (naturally or experimentally) infected with several viruses including tomato black ring virus (genus Nepovirus; Smith, 1957), cucumber mosaic virus (Cucumovirus; Schmelzer, 1963), arabis mosaic virus (Nepovirus; Dupuis et al, 2008), ligustrum virus A (Carlavirus; Igori et al, 2016), ligustrum necrotic ringspot virus (Carlavirus; Scott and Zimmerman, 2008), privet ringspot virus (Ilarvirus; Aboughanem-Sabanadzovic et al, 2016) and privet leaf blotch-associated virus (Idaeovirus; Navarro et al, 2017).…”

Identification and Molecular Characterization of a Novel Hordeivirus Associated With Yellow Mosaic Disease of Privet (Ligustrum vulgare) in Europe

Wild plants serve as a large reservoir of known and yet-unknown viruses and as a source of viral pathogens of cultivated plants. Yellow mosaic disease of forest shrub Ligustrum vulgare (privet) was recurrently observed in Europe for more than 100 years. Using a universal virus identification approach based on deep sequencing and de novo assembly of viral small interfering (si)RNAs we identified a causative agent of this disease in Switzerland and reconstructed its complete 3-segmented RNA genome. Notably, a short 3′-terminal common region (CR) attached to each segment via a ∼53–71 nucleotide poly(A) tract, as determined by RT-PCR sequencing, was initially identified as an orphan siRNA contig with conserved tRNA-like secondary structure. Phylogenomic analysis classified this virus as a novel member in the genus Hordeivirus of family Virgaviridae, which we named ligustrum mosaic virus (LigMV). Similar to other hordeiviruses, LigMV formed rod-shape virions (visualized by electron microscopy), was transmitted through seeds and could also be mechanically transmitted to herbaceous hosts Chenopodium quinoa and Nicotiana benthamiana. Blot hybridization analysis identified genomic and subgenomic RNAs, sharing the 3′-CR and likely serving as monocistronic mRNAs for seven evolutionarily-conserved viral proteins including two subunits of viral RNA-dependent RNA polymerase, coat protein, triple gene block proteins mediating viral movement and cysteine-rich suppressor of RNA silencing. Analysis of size, polarity, and hotspot profiles of viral siRNAs suggested that they are produced by the plant antiviral Dicer-like (DCL) proteins DCL2 and DCL4 processing double-stranded intermediates of genomic RNA replication. Whole genome sequencing of French and Austrian isolates of LigMV revealed its genetic stability over a wide geographic range (>99% nucleotide identity to Swiss isolates and each other), suggesting its persistence and spread in Europe via seed dispersal.

Arabis mosaic virus (AMY) , in association with its vector Xiphinema diversicaudatum, is recorded for the first time in New Zealand.It was found occurring naturally on tamarillos (tree tomatoes) and was transferred experimentally to produce symptoms on Buttercup squash, cowpea, cucumber, french bean, lupin, Petunia, soybean, and tobacco. AMY was also transmitted to celery, coriander, pea, and sweet pea, but produced no symptoms in these hosts.No nematode or seed transmission experiments were attempted. Surveys showed the nematode vector to be present in only small numbers but regularly associated with tamarillo plants infected with AMY.The host range, physical properties, serology, and electron microscopy of the virus suggest that it is a strain of arabis mosaic virus.

“…ArMV has a wide natural host range including a number of economically important crop plants [1]. When mechanically inoculated, 93 species from 28 dicotyledonous families were shown to be infected [2]. The most common symptoms induced by the virus are mosaic, leaf mottling and flecking, stunting and several forms of deformation including enations.…”

Comparisons of complete RNA-2 sequences, pathological and serological features among three Japanese isolates of Arabis mosaic virus

Arabis mosaic virus lily and narcissus isolates (ArMV-Li and ArMV-Na) induced severe necrotic spots on Chenopodium quinoa, whereas ArMV butterbur isolate (ArMV-Bu) caused symptomless infection in the plant. The accumulation level of ArMV-Bu in upper non-inoculated leaves of C. quinoa was comparable to that of ArMV-Li or -Na. The agar gel double-diffusion test using an antiserum against ArMV-Li showed ArMV-Li was closely related to ArMV-Na, but not to ArMV-Bu. The RNAs-2 of ArMV-Li, -Na, and -Bu consist of 3707, 3709, and 3789 nucleotides, and they contain one open reading frame encoding a putative polyprotein of 1083, 1084, and 1122 amino acids, respectively. The overall identity of RNA-2 of ArMV-Li displayed more than 90% with ArMV-Na, but less than 70% with ArMV-Bu. A phylogenetic analysis of 2A sequences from ArMV isolates revealed ArMV-Bu was not categorized in any cluster. ArMV-Bu is a unique isolate from the point of view of pathological and serological features, and nucleotide sequence.
