RESUMO
A novel virus named Aconitum amalgavirus 1 (AcoAV-1) was identified in Chinese aconite (Aconitum carmichaelii) plants. The complete genome of AcoAV-1 is 3,370 nucleotides long, containing two partially overlapping open reading frames encoding a putative coat protein and a RNA-dependent RNA polymerase, respectively. Its fusion protein shares 34.9%-50.7% amino acid sequence identity with other amalgaviruses. Phylogenetic analysis showed that this virus formed a clade with blueberry latent virus and four other related viruses, suggesting that it belongs to the genus Amalgavirus in the family Amalgaviridae.

A novel enamovirus was identified in common bean plants with disease symptoms. Its genome of 5,781 nucleotides (nt) contains five open reading frames. This virus and other members of the genus Enamovirus share 50.4-68.4% nucleotide sequence identity in the complete genome and 19.9-51.9% amino acid sequence identity in the P0 protein, 24.9-52.5% in P1, 33.4-62.9% in P1-P2, 30.6-81.1% in P3, and 32.3-74.2% in P3-P5. Phylogenetic analysis showed that the virus is most closely related to alfalfa enamovirus 1 and pea enation mosaic virus 1 in the genus Enamovirus of the family Solemoviridae. These results suggest that this virus, tentatively named "bean enamovirus 1", should be classified as a member of a new species in the genus Enamovirus.
