Cannabis Virome Reconstruction and Antiviral RNAi Characterization through Small RNA Sequencing.

ABSTRACT: Viral infections pose an emerging threat to hemp (Cannabis sativa) cultivation. We used Illumina small (s)RNA sequencing for virome reconstruction and characterization of antiviral RNA interference (RNAi) in monoecious and dioecious hemp varieties, which exhibited different virus-like symptoms. Through de novo and reference-based sRNA assembly, we identified and reconstructed Cannabis cryptic virus (family Partitiviridae), Cannabis sativa mitovirus 1 (Mitoviridae) and Grapevine line pattern virus (Bromoviridae) as well as a novel virus tentatively classified into Partitiviridae. Members of both Partitiviridae and Bromoviridae were targeted by antiviral RNAi, generating 21 nt and, less abundant, 22 nt sRNAs from both strands of the ent
