RNA Viral Metagenome Analysis of Subnanogram dsRNA Using Fragmented and Primer Ligated dsRNA Sequencing (FLDS).

Fragmented and primer ligated dsRNA sequencing (FLDS) is a sequencing method applicable to long double-stranded RNA (dsRNA) that enables the complete genome sequencing of both double- and single-stranded RNA viruses. However, the application of this method on a low amount of dsRNA has been hindered by adaptor dimer formation during cDNA amplification and sequence library preparation. We herein developed FLDS ver.

Diverged and Active Partitiviruses in Lichen.

The lichen is a microbial consortium that mainly consists of fungi and either algae (Viridiplantae) or cyanobacteria. This structure also contains other bacteria, fungi, and viruses. However, RNA virus diversity associated with lichens is still unknown.
