Bunyavirales

Summary[edit] Description: English: Prototypic phlebovirus virion and genome organization. (A) Virus particles contain the pseudocircularized tripartite single-stranded RNA genome, packaged into virus-sense RNPs (vRNPs) by nucleocapsid protein N and associated with the viral RNA-dependent RNA polymerase (RdRp) L, within a lipid envelope covered by heterodimers of glycoproteins Gn and Gc; and (B) the three viral genome segments large (L), medium (M) (both being purely negative-sense), and small (S) (ambisense) code for the structural proteins L, the Gn and Gc, and N, respectively. Viral mRNAs contain a 5′-cap (dot) and short heterogenous host-derived sequences. mRNAs transcribed from genomic RNAs are shown as grey arrows. The nonstructural protein NSs mRNA (green arrow) is synthesized from antigenomic RNA (two-colored arrow). Dipteran-borne phleboviruses also encode a nonstructural protein on the M segment (NSm).

Summary[edit] Description: English: Maximum likelihood phylogenetic tree of the amino acid sequences of the RNA-dependent RNA polymerase (RdRp). The virus families are color-coded and the hosts for viruses within each group are indicated in the outermost circle. The six groups are identified in the legend and the boundaries of these groups are indicated in the outer ring of the phylogeny. Group I: Peribunyaviridae, Phenuiviridae, and Cruliviridae. Group II: Fimoviridae and Tospoviridae. Group III: Hantaviridae and Phasmaviridae. Group IV: Arenaviridae and Mypoviridae. Group V: Nairoviridae and Wupedeviridae. Group VI: Phenuiviridae, Leishbuviridae, and unassigned species. Clade validation is based on the approximate likelihood ratio test (aLRT)-Shimodaira–Hasegawa (SH)-like test values.
