Summary: Members of the family Pospiviroidae have single-stranded circular RNA genomes with a rod-like or quasi-rod-like conformation, containing a central conserved region for replication in the nucleus through an asymmetric RNA-RNA rolling-circle mechanism. Unlike viroids in the family Avsunviroidae, Pospiviroidae members do not possess hammerhead ribozymes. The family Pospiviroidae includes multiple genera and more than 25 species.

Summary: Nanoviridae is a family of plant viruses with small isometric virions and multipartite, circular, single-stranded DNA genomes. Members of this family are associated with satellite-like cssDNAs, predominantly infecting legumes and Zingiberales plants, requiring a virus-encoded helper factor for transmission by aphids.

Summary: Members of the family Sphaerolipoviridae are non-enveloped tailless icosahedral virions with internal lipid membrane. They have a linear double-stranded DNA genome of about 30 kbp, with terminal repeats and proteins. The capsid has a T=28 dextro symmetry and is composed of two major capsid protein types. Spike complexes can be found at fivefold vertices. Sphaerolipoviruses infect haloarchaea in the class Halobacteria and have a narrow host range and lytic life cycle. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Sphaerolipoviridae, available at ictv.global/report/sphaerolipoviridae.

Summary: The family Hadakaviridae consists of capsidless viruses called Hadakavirus, which have a segmented positive sense RNA genome with 10 or 11 segments. These viruses infect ascomycetous filamentous fungi. Unlike the related polymycovirids and certain encapsidated picorna-like viruses, hadakavirids lack a capsid and therefore cannot be pelleted by conventional ultracentrifugation; they are susceptible to ribonuclease in host tissue homogenates. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Hadakaviridae, available at ictv.global/report/hadakaviridae.

Summary: Members of the family Inoviridae are non-enveloped flexible filamentous bacteriophages with super-coiled, circular, positive-sense, single-stranded DNA genomes encoding 7-15 proteins. They attach to the pili of Gram-negative bacteria, replicate their DNA by a rolling-circle mechanism, and release progeny without killing the host. Phage DNA can persist extra-chromosomally or integrate into the bacterial genome.

Summary: Pseudoviridae is a family of reverse-transcribing viruses with long terminal repeats (LTRs) commonly found integrated in the genomes of diverse plants, fungi and animals. They form icosahedral virus particles inside the cell, lacking an extracellular phase like most other viruses.

Summary: The complete genome sequence of a previously uncharacterized sugarcane-infecting virus of the genus Ampelovirus was obtained using high-throughput sequencing (HTS) and rapid amplification of cDNA ends. It belongs to a new species of Ampelovirus, and an RT-PCR diagnostic assay was developed to detect and study the virus. This research provides important insights into the epidemiology and management of this sugarcane virus.

Summary: The genetic diversity and evolutionary history of the epidemic plum pox virus strain M (PPV-M) were studied in this research. The genomes of 69 PPV-M isolates from Turkey were sequenced and analyzed, revealing a high genetic diversity and the grouping of Turkish PPV-M isolates into two sister clades. The genetic diversity of Turkish PPV-M isolates was found to be comparable to that of isolates from other countries.

Summary: Quinone outside inhibitor (QoI) fungicides have been widely used to manage soybean diseases, but resistant isolates have been found. The study analyzed fitness parameters and found that resistant isolates had better colony growth but produced fewer conidia compared to wild-type isolates. The study suggests that the resistant isolates are stable and may have advantages in the population.

Summary: A study found that grapevine samples infected with grapevine-associated jivivirus 1 (GaJV-1) consistently detected 7 additional RNA molecules in addition to the previously identified 3 genomic RNAs, with 6 of them belonging to one family and 1 to another family. These RNA molecules have conserved non-coding regions and protein domains. Furthermore, analysis of pecan transcriptomic data identified two more jiviviruses and additional genomic RNAs with homologies to GaJV-1.

Summary: The analysis revealed the presence of viroid isolates related to apple dimple fruit viroid (ADFVd) in Spanish pomegranate fruits showing yellow rings. Evidence for similar ADFVd isolates in pomegranate trees in Israel was found through the analysis of pomegranate public RNASeq data. Plum viroid I (PVd-I) isolates were also identified in two datasets from Israel, suggesting the presence of this second viroid in pomegranate. Full length ADFVd genomic sequences have been recovered, expanding knowledge on the diversity of this viroid and the pomegranate virome.

Summary: High-throughput sequencing of plant tissues is a crucial tool for plant virologists to detect plant viruses. However, during the analysis of the data, researchers often neglect sequences without homologies to viruses, which may contain traces of other pathogens. In this study, we re-analyzed RNA-seq datasets and found non-viral plant pathogens, including fungi, insects, and mites. This highlights the potential of using total RNA-seq data for detecting various plant pathogens.

Summary: Recent developments in high-throughput sequencing technologies and bioinformatics have greatly impacted virus discovery in virology research. However, the potential bias introduced by bioinformatics analyses in genome reconstruction and SNP detection has not been widely addressed. To address this issue, a large-scale performance testing was conducted to evaluate the ability of different bioinformatics pipelines in detecting variants of pepino mosaic virus (PepMV) in plant virology laboratories.

Summary: A new mycovirus, identified as Plasmopara-viticola-lesion-associated mononegaambi virus 3 (Penicillimonavirus gammaplasmoparae), was found in grapevine plants exhibiting upward curling symptomatology and premature decline. The complete bipartite genome of P. gammaplasmoparae was determined, and it is the first complete genomic sequence for this genus. The study also suggests the presence of the grapevine powdery mildew pathogen, Erysiphe necator, and its potential interaction with P. gammaplasmoparae.
