“…In this phylogenetic tree, CCGaV was nested, together with phlebo‐like viruses, at a basal node of a supergroup including phleboviruses and tenuiviruses at more apical nodes (Figs b and S3, see Supporting Information). This and other clades in the ML phylogenetic tree are consistent with similar phylogenetic reconstructions inferred by others (Guterres et al , ; Li et al , ; Marklewitz et al , ). In addition, a similar tree topology was obtained by the Bayesian Markov Chain Monte Carlo (MCMC) analysis (see below), thus supporting the close phylogenetic relationships between the plant‐infecting CCGaV and some invertebrate‐specific nsRNA viruses.…”

“…The recent identification of a huge number of arthropod‐restricted nsRNA viruses and their phylogenetic relationships with viruses infecting divergent host taxa support the proposal that all the extant nsRNA viruses, including those with dual tropism (invertebrates/vertebrates or invertebrates/plants) and those restricted to vertebrates, plants or fungi, derived from ancestors exclusively infecting arthropods (Guterres et al , ; Junglen, ; Li et al , ). The Bayesian phylogeny‐based reconstruction of the ancestral host using the RdRp (Fig.…”

A novel negative-stranded (ns) RNA virus associated with a severe citrus disease reported more than 80 years ago has been identified. Transmission electron microscopy showed that this novel virus, tentatively named citrus concave gum-associated virus, is flexuous and non-enveloped. Notwithstanding, its two genomic RNAs share structural features with members of the genus Phlebovirus, which are enveloped arthropod-transmitted viruses infecting mammals, and with a group of still unclassified phlebo-like viruses mainly infecting arthropods. CCGaV genomic RNAs code for an RNA-dependent RNA polymerase, a nucleocapsid protein and a putative movement protein showing structural and phylogenetic relationships with phlebo-like viruses, phleboviruses and the unrelated ophioviruses, respectively, thus providing intriguing evidence of a modular genome evolution. Phylogenetic reconstructions identified an invertebrate-restricted virus as the most likely ancestor of this virus, revealing that its adaptation to plants was independent from and possibly predated that of the other nsRNA plant viruses. These data are consistent with an evolutionary scenario in which trans-kingdom adaptation occurred several times during the history of nsRNA viruses and followed different evolutionary pathways, in which genomic RNA segments were gained or lost. The need to create a new genus for this bipartite nsRNA virus and the impact of the rapid and specific detection methods developed here on citrus sanitation and certification are also discussed.

“…The RdRp sequences for 253 species belonging to arthropod, plant, protozoan, and vertebrate infecting viruses within Bunyavirales were compiled ( Supplementary Table S1 ) to build an ML phylogeny. The ML tree in Figure 1 covers 12 families and one unassigned species and, has three deeply rooted clades with viruses of insect hosts at the basal position as reported in Guterres et al (2017) [ 6 ]. Within these three clades are six major lineages that we identified as groups I through VI ( Figure 1 ).…”

“…The phylogenetic positions of the Emaravirus and Orthophasmavirus preGP and N proteins suggest a similar ancestry. The Orthotospovirus preGP proteins are phylogenetically positioned near the Orthonairoviruses and Mammarenaviruses while the N proteins extend from a node that is affiliated with two dipteran infecting virus members of Phenuiviridae in group II [ 6 ]. These observations suggest that the evolutionary connections among viruses with Bunyavirales involve a network of gene exchanges.…”

“…The origins and evolutionary history of plant viruses within Bunyavirales are unclear. While phylogenetic studies suggest common ancestral origins of vertebrate and arthropod infecting viruses, the ancestral lineages of plant viruses within this taxonomic order have not been well studied [ 5 , 6 ]. Extensive sampling of arthropods (crustaceans, centipedes, insects, and spiders) have revealed new species of negative-sense RNA viruses, and many appear to be ancestral to viruses that cause diseases in vertebrate hosts [ 5 , 7 , 8 , 9 , 10 ].…”

Bunyavirales are negative-sense segmented RNA viruses infecting arthropods, protozoans, plants, and animals. This study examines the phylogenetic relationships of plant viruses within this order, many of which are recently classified species. Comprehensive phylogenetic analyses of the viral RNA dependent RNA polymerase (RdRp), precursor glycoprotein (preGP), the nucleocapsid (N) proteins point toward common progenitor viruses. The RdRp of Fimoviridae and Tospoviridae show a close evolutional relationship while the preGP of Fimoviridae and Phenuiviridae show a closed relationship. The N proteins of Fimoviridae were closer to the Phasmaviridae, the Tospoviridae were close to some Phenuiviridae members and the Peribunyaviridae. The plant viral movement proteins of species within the Tospoviridae and Phenuiviridae were more closely related to each other than to members of the Fimoviridae. Interestingly, distal ends of 3′ and 5′ untranslated regions of species within the Fimoviridae shared similarity to arthropod and vertebrate infecting members of the Cruliviridae and Peribunyaviridae compared to other plant virus families. Co-phylogeny analysis of the plant infecting viruses indicates that duplication and host switching were more common than co-divergence with a host species.
