Replicating circular RNAs are independent plant pathogens known as viroids, or act to modulate the pathogenesis of plant and animal viruses as their satellite RNAs. The rate of discovery of these subviral pathogens was low over the past 40 years because the classical approaches are technical demanding and time-consuming. We previously described an approach(More)
Disconnected Interacting Protein 1 (DIP1) is a dsRNA-binding protein that participates in a wide range of cellular processes. Whether DIP1 is involved in innate immunity remains unclear. Here, DIP1 was found to play an antiviral role in S2 cells. Its antiviral action is specific for DCV infection and not for DXV infection. dip1 mutant flies are(More)
The complete genome sequence of a novel virus, provisionally named tobacco virus 1 (TV1), was determined, and this virus was identified in leaves of tobacco (Nicotiana tabacum) exhibiting leaf mosaic and yellowing symptoms in Anhui Province, China. The genome sequence of TV1 consists of 15,395 nucleotides with 61.6 % nucleotide sequence identity to mint(More)
The invasion of plant by viruses cause major damage to plants and reduces crop yield and integrity. Devastating plant virus infection has been experienced at different times all over the world, which are attributed to different events of mutation, re-assortment and recombination occurring in the viruses. Strategies for proper virus management has been(More)
The complete genome of a novel virus, provisionally named areca palm velarivirus 1 (APV1), was identified in areca palm exhibiting leaf yellowing symptoms in Hainan province, China. The genome of APV1 consists of 16,080 nucleotides and possesses 11 open reading frames (ORFs), sharing 56.4 % nucleotide sequence identity with little cherry virus 1(More)
