Abstract Secoviridae family contains single stranded RNA genome-containing viruses that infect plants. In the present study, we mined publicly available plant transcriptomes and identified sixty-one putative novel secoviral sequences in various species ranging from bryophytes to trees, which increased known diversity by approximately 0.5-fold. Of viral sequences, 13 were monopartite 48 bipartite, of 52 secoviruses coding-complete nine partial. Except for small open reading frames (ORFs) determined waikaviral genomes RNA2 torradoviruses, all recovered genomes/genome segments contained a large ORF encoding polyprotein. Based on genome organization, sequence similarity members, phylogeny secovirus demarcation criteria, but three assigned different genera- Cheravirus (3), Comovirus (2), Fabavirus (5), Nepovirus (29), Sadwavirus Sequivirus (1), Stralarivirus Torradovirus (4) Waikavirus (10). Genome organization two waika-like resembled recently virus- Triticum aestivum secovirus. Phylogenetic analysis revealed host-waikavirus co-evolution pattern few waika- viruses, phylogenetic nepoviruses clustering viruses. The study paves way further studies understanding biological properties secoviruses.

Abstract Kitaviruses are plant-infecting, non-systemic disease-causing viruses with multipartite single-stranded RNA genomes. Despite their importance, knowledge on kitaviruses is limited in comparison other plant virus groups, mainly because of the lesser number identified and characterized isolates. In present study, we explored (meta)transcriptome data available public domain genome sequences fifteen putative novel blunerviruses species, including three gymnospermic monocot species. Four segments (RNAs 1–4) ten were recovered, whilst atleast two recovered for remaining viruses. Monocistronic RNA1 encodes methyltransferase (MET)-helicase (HEL) polyprotein, except Nanmu blunervirus 1 that a relatively larger MET-HEL-RNA-dependent polymerase (RdRp) polyprotein. RNAs 2 4, respectively viruses, encode HEL-RdRp polyprotein movement protein (MP). Three to four open reading frames (ORFs) determined RNA3 which conserved ORF3, always negevirus membrane (SP24) homolog. Phylogenetic analysis grouped known blunerviruses. Based organization, sequence identities encoded proteins phylogeny, regarded as new members genus Blunervirus. The study paves way initiating further studies understanding biological properties, economic importance geographical distribution
