| Sumario: | Despite a surge of RNA virome sequencing in recent years, there are still many RNA viruses to uncover—as indicated by the relevance of viral dark matter to RNA virome studies (i.e., putative viruses that do not match to taxonomically identified viruses). This study explores a unique site, a high-rate algal pond (HRAP), for culturing industrially microalgae, to elucidate new RNA viruses. The importance of viral-host interactions in aquatic systems are well documented, and the ever-expanding microalgae industry is no exception. As the industry becomes a more important source of sustainable plastic manufacturing, a producer of cosmetic pigments and alternative protein sources, and a means of CO<sub>2</sub> remediation in the face of climate change, studying microalgal viruses becomes a vital practice for proactive management of microalgae cultures at the industrial level. This study provides evidence of RNA microalgal viruses persisting in a CO<sub>2</sub> remediation pilot project HRAP and uncovers the diversity of the RNA virosphere contained within it. Evidence shows that family <i>Marnaviridae</i> is cultured in the basin, alongside other potential microalgal infecting viruses (e.g., family <i>Narnaviridae</i>, family <i>Totitiviridae</i>, and family <i>Yueviridae</i>). Finally, we demonstrate that the RNA viral diversity of the HRAP is temporally dynamic across two successive culturing seasons. |
