Nandina mosaic virus is an isolate of Plantago asiatica mosaic virus

Abstract

The complete nucleotide sequence of the genome of Nandina mosaic virus (NaMV), which has tentatively been assigned to the genus Potexvirus, is reported. The sequence is 6066 nt in length, excluding the poly(A) tail, and contains ORFs coding for proteins of 155, 25, 12, 13, and 21 kDa (ORFs 1-4 and the CP), respectively. The genomic organization of the virus and the signature motifs in the putative protein products are similar to the data reported for potexviruses for which complete sequences are known. Phylogenetic comparisons indicated that NaMV is most closely related to Plantago asiatica mosaic virus (PlAMV). Pairwise comparisons of the sequence data for these two viruses indicate that, based on criteria recently proposed for genera within the family Flexiviridae, NaMV and PlAMV should be considered to be strains/ isolates of the same viral species. Both NaMV and PlAMV were first reported in 1976 but, as PlAMV was sequenced first, this name should take precedence with the name NaMV being relegated to a synonym.

Plantago asiatica mosaic virus: An emerging plant virus causing necrosis in lilies and a new model RNA virus for molecular research

“…However, PlAMV isolates, in general, have genomic diversity within the species. As stated above, PlAMV has been isolated from a variety of weed plants, including P. asiatica (Komatsu et al, 2008, 2017; Kostin & Volkov, 1976; Lim et al, 2016; Solovyev et al, 1994), N. domestica (Hughes et al, 2005; Komatsu et al, 2017), and R. glutinosa (Kwak et al, 2018; Uehara‐Ichiki et al, 2018). These PlAMV isolates from plants other than ornamental lilies share less than 85% nucleotide identities with lily‐infecting European isolates (Hammond & Reinsel, 2018; Komatsu et al, 2017), therefore the ancestral host plant from which lily‐infecting isolates were derived is still unclear.…”

“…However, a potexvirus was reported to infect cultivated plants of the ornamental shrub N. domestica (heavenly bamboo) in California, USA (Moreno et al, 1976), and later was named Nandina mosaic virus (Zettler et al, 1980). Finally, it was classified as an isolate of PlAMV when its complete genome sequence was determined (Hughes et al, 2005).…”

Plantago asiatica mosaic virus.

“…Genus Potexvirus, Family Flexiviridae. Nandina mosaic virus (NaMV) is a synonym of PlAMV (Hughes et al, 2005). It is a close phylogenetic relative of Tulip virus X (Komatsu et al 2008).…”

Molecular detection and characterization of a divergent isolate of Plantago asiatica mosaic virus in Plantago asiatica

“…To date, the complete genomic sequences of 17 PlAMV isolates are available in the GenBank database. Although the first-reported isolate was characterized from P. asiatica [10], the other isolates of PlAMV have been identified in Lilium spp., Nandina domestica, and Primula sieboldii [3,5] except for one PlAMV isolate from P. asiatica in this work. The majority of these have been identified in Lilium spp.…”
