“…This was reported first in the Netherlands (EPPO, 2011) and in Chile in 2013 (Vidal et al, 2016). However, soon after its first known occurrence in commercial lily hybrids, PlAMV was detected in commercial lily stocks in many other countries in Europe and around the world (Anderson et al, 2013; Chen et al, 2013; Hammond et al, 2015; Harju et al, 2018; Kim et al, 2015; Li et al, 2017; Montero‐Astúa et al, 2017; Pájtli et al, 2015; Parrella et al, 2015; Xu et al, 2017). Interestingly, the isolates from commercial lily products (“European‐like” isolates) have extremely closely related sequences, quite distinct from those obtained from edible lilies in Japan (Hammond & Reinsel, 2018; Komatsu et al, 2017; Ozeki et al, 2006).…”

Taxonomy: Plantago asiatica mosaic virus belongs to the genus Potexvirus in the family Alphaflexiviridae of the order Tymovirales. Virion and genome properties: Plantago asiatica mosaic virus (PlAMV) has flexuous virions of approximately 490-530 nm in length and 10-15 nm in width. The genome of PlAMV consists of a single-stranded, positive-sense RNA of approximately 6.13 kb. It contains five open reading frames (ORFs 1-5), encoding a putative viral polymerase (RdRp), movement proteins (triple gene block proteins, TGBp1-3), and coat protein (CP), respectively. Host range: PlAMV has an exceptionally wide host range and has been isolated from various wild plants, including Plantago asiatica, Nandina domestica, Rehmannia glutinosa, and other weed plants. Experimentally PlAMV can infect many plant species including Nicotiana benthamiana and Arabidopsis thaliana. It also infects ornamental lilies and frequently causes severe necrotic symptoms. However, host range varies depending on isolates, which show significant biological diversity within the species. Genome diversity: PlAMV can be separated into five clades based on phylogenetic analyses; nucleotide identities are significantly low between isolates in the different clades. Transmission: PlAMV is not reported to be transmitted by biological vectors. Virions of PlAMV are quite stable and it can be transmitted efficiently by mechanical contact. Disease symptoms: PlAMV causes red-rusted systemic necrosis in ornamental lilies, but it shows much weaker, if any, symptoms in wild plants such as P. asiatica. Control: Control of the disease caused by PlAMV is based mainly on rapid diagnosis and elimination of the infected bulbs or plants.

“…PlAMV has not (to our knowledge) been reported to naturally infect P. lanceolata, but does infect this host experimentally (Hammond, 2018). In the UK, PlAMV has not been previously reported except for interceptions of infected imported lilies (Harju et al, 2018), and as such is still subject to plant health regulation. Should PlVX have proven to be synonymous with PlAMV, and present in the wider environment in Europe, then regulatory controls on PlAMV would be no longer necessary.…”

Sequence analysis of 43‐year old samples of Plantago lanceolata show that Plantain virus X is synonymous with Actinidia virus X and is widely distributed

Plantain virus X was first recognized by the ICTV as a species in the genus Potexvirus in 1982. However, because no sequence was available for plantain virus X (PlVX), abolishing the species was proposed to the Flexiviridae working group of the ICTV in 2015. This initiated efforts to sequence the original isolates from Plantago lanceolata samples. Here we report the full‐genome sequencing of two original isolates of PlVX, which demonstrate that the virus is synonymous to Actinidia virus X, a species previously reported from kiwifruit (Actinidia sp.) and blackcurrant (Ribes nigrum). PlVX was previously noted to be widespread in the UK in P. lanceolata. This report additionally presents novel data on the distribution and diversity of PlVX, collected at the same site as the original UK isolates, and from three independent surveys, two in the Netherlands and one in Belgium. This study also includes two new host records for PlVX, Browallia americana and Capsicum annuum (sweet pepper), indicating the virus is more widespread and infects a broader range of hosts than previously reported. This stresses the importance of surveys of noncultivated species to gain insight into viral distribution and host range. This study also demonstrates the value of generating sequence data for isolates retained in virus collections. Additionally, it demonstrates the potential value in prepublication data sharing for giving context to virus detections such as the four independent studies here which, when combined, give greater clarity to the identity, diversity, distribution, and host range of plantain virus X.
