Here, we report the complete genome sequence of Jasminum polyanthum nepovirus 1 (JPV1), a novel virus associated with foliar ringspot symptoms in Jasminum polyanthum (Oleaceae). The genome of JPV1 consists of RNA1 and RNA2, both of which are monocistronic and are 7081 nt and 4212 nt in length, respectively. RNA1 encodes six functional proteins, including the X1 protein, X2 protein, NTP-binding protein (NTB), VPg protein, protease cofactor (Pro), and RNA-dependent RNA polymerase (RdRp), while RNA2 encodes three functional proteins: the 2A protein, movement protein (MP), and capsid protein (CP).

- A new dsRNA virus called "Valeriana jatamansi cryptic virus 1" (VJCV1) was found in Valeriana jatamansi plants showing symptoms in Yunnan, with its complete genome sequenced.
- VJCV1 has two segments of dsRNA, which code for an RNA polymerase and a coat protein, and features unique structures typical of the Alphapartitivirus genus.
- Phylogenetic analysis indicates that VJCV1 is distinct from other known viruses in the genus, suggesting it should be classified as a new species within Alphapartitivirus, marking the first virus from this group identified in Valeriana plants.
Article Synopsis
- Lily virus X (LVX) is a positive-sense ssRNA virus from the Potexvirus genus, primarily infecting plants in the Lilium and Tricyrtis genera and was first reported in asymptomatic lilies in England.
- In China, the perennial plant Paris polyphylla var. yunnanensis, known for its medicinal use, showed viral symptoms from 2019 to 2022 with significant disease incidence across multiple fields.
- Viral pathogen identification involved RNA extraction from symptomatic leaves, leading to the discovery of LVX along with other viruses like PMNV, PAPV, and DMV through RNA sequencing and assembly techniques.
Article Synopsis
- Fusarium diseases affect various crops, causing significant production issues in both agricultural and natural environments, leading to serious economic and ecological consequences.
- Researchers discovered a new mycovirus called "Fusarium fusarivirus 1" (FuFV1) found in a strain of Fusarium sp., which has a genome consisting of 6,391 nucleotides and three open reading frames (ORFs) associated with important viral functions.
- Phylogenetic analysis indicates that FuFV1 is closely related to Fusarium poae fusarivirus 1, suggesting it should be classified as a novel member of the genus Alphafusarivirus within the Fusariviridae family.
Article Synopsis
- A new single-stranded RNA virus named "Valeriana jatamansi tymovirus 1" (VaJV1) was isolated from Valeriana jatamansi plants in Yunnan Province, China, which exhibited vein-clearing symptoms.
- The complete genome of VaJV1 is 6,215 nucleotides long and has three open reading frames (ORFs), fitting the typical structure of tymoviruses.
- BLASTn analysis revealed that VaJV1 shares significant genetic similarity with okra mosaic virus, and phylogenetic analysis suggests it is a new species within the Tymovirus genus.
