Characterization and partial genome sequence of stocky prune virus, a new member of the genus Cheravirus Inra
Candresse, T.; Svanella-Dumas, L.; Le Gall, O..
Characterization of a seemingly new spherical virus isolated from severely affected plum trees in south-western France indicated that its divided genome is composed of two single-stranded, polyadenylated RNAs of approximately 7.4 and 3.7 kb. Its particles are composed of three coat protein subunits of approximately 23, 23.5, and 24.5 kDa. Partial sequencing of the genomic RNAs indicated that this new virus, tentatively named stocky prune virus (StPV), is distantly related to the two sequenced cheraviruses, cherry rasp leaf virus (CRLV) and apple latent spherical virus (ALSV). StPV should be regarded as a new member in the unassigned genus Cheravirus.

Cheravirus and Sadwavirus: two unassigned genera of plant positive-sense single-stranded RNA viruses formerly considered atypical members of the genus Nepovirus (family Comoviridae) Inra
Le Gall, O.; Sanfaçon, H.; Ikegami, M.; Iwanami, T.; Jones, T.; Karasev, A.; Lehto, K.; Wellink, J.; Wetzel, T.; Yoshikawa, N..
The genus Nepovirus (family Comoviridae) was known both for a good level of homogeneity and for the presence of atypical members. In particular, the atypical members of the genus differed by the number of capsid protein (CP) subunits. While typical nepoviruses have a single CP subunit with three structural domains, atypical nepoviruses have either three small CP subunits, probably corresponding to the three individual domains, or a large and a small subunit, probably containing two and one structural domains, respectively. These differences are corroborated by hierarchical clustering based on sequences derived from both genomic RNAs. Therefore, these atypical viruses are now classified in two distinct genera, Cheravirus (three CP subunits; type species...

Picornavirales , a proposed order of positive-sense single-stranded RNA viruses with a pseudo-T = 3 virion architecture Inra
Le Gall, O.; Christian, P.; Fauquet, C.M.; King, A.M.Q.; Knowles, N.J.; Nakashima, N.; Stanway, G.; Gorbalenya, A.E..
Despite the apparent natural grouping of “picorna-like” viruses, the taxonomical significance of this putative “supergroup” was never addressed adequately. We recently proposed to the ICTV that an order should be created and named Picornavirales, to include viruses infecting eukaryotes that share similar properties: (i) a positive-sense RNA genome, usually with a 5′-bound VPg and 3′-polyadenylated, (ii) genome translation into autoproteolytically processed polyprotein(s), (iii) capsid proteins organized in a module containing three related jelly-roll domains which form small icosahedral, non-enveloped particles with a pseudo-T = 3 symmetry, and (iv) a three-domain module containing a superfamily III helicase, a (cysteine) proteinase with a...

Secoviridae: a proposed family of plant viruses within the order Picornavirales that combines the families Sequiviridae and Comoviridae, the unassigned genera Cheravirus and Sadwavirus, and the proposed genus Torradovirus Inra
Sanfaçon, H.; Wellink, J.; Le Gall, O.; Karasev, A.; van der Vlugt, R.; Wetzel, T..
The order Picornavirales includes several plant viruses that are currently classified into the families Comoviridae (genera Comovirus, Fabavirus and Nepovirus) and Sequiviridae (genera Sequivirus and Waikavirus) and into the unassigned genera Cheravirus and Sadwavirus. These viruses share properties in common with other picornavirales (particle structure, positive-strand RNA genome with a polyprotein expression strategy, a common replication block including type III helicase, a 3C-like cysteine proteinase and type I RNA-dependent RNA polymerase). However, they also share unique properties that distinguish them from other picornavirales. They infect plants and use specialized proteins or protein domains to move through their host. In phylogenetic analysis...
