Recent metagenomic studies in insects identified many sequences unexpectedly closely related to plant virus genes. Here we describe a new example of this kind. insect R1 LINEs with an additional C-terminal domain in their open reading frame 2. This domain is similar to NTPase/helicase (SF1H) domains. https://thebookmarkid.com/story19599675/mass-balance-of-cenozoic-andes-amazon-source-to-sink-system-mara%C3%B1%C3%B3n-basin-peru
