摘要

Next Generation Sequencing (NGS) and bioinformatic analysis have made identifying viruses from transcriptome datasets in the public domain more popular. Here, we have identified the coding-complete genome sequence of a novel dsRNA mycovirus of the genus, Gammapartitivirus from an endophytic Fusarium oxysporum for which the name, Fusarium oxysporum partitivirus 2 is proposed. It has a bisgmented, monocistronic genome with 1742 bp long dsRNA 1 and 1421 bp long dsRNA 2. The dsRNA1 and dsRNA2 contain a single open reading frame (ORF) coding for the RNA-dependent RNA polymerase (RdRp) of 536 amino acids and the coat protein of 419 amino acids, respectively. This is the first report of a fungal virus identified by the transcriptome data mining of Fusarium oxysporum from India.
