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: The ability to produce IL-2 identifies constituents of the expanded CD8 T cell effector pool with stem-like features, which exhibit superior protective powers. The production of IL-2 by cells attenuates the ability to receive IL-2 signals, limiting terminal effector formation and conferring superior protection. Non-producing effector cells, on the other hand, gain effector traits at the expense of memory formation. Despite distinct properties during the effector phase, IL-2-producing and non-producing CD8 T cells converge transcriptionally as memory matures, forming populations with equal recall abilities.

Summary: This study explored the differences in bacterial diversity during the four developmental stages of the black soldier fly (BSF) using a metabarcoding approach. The results showed significant changes in bacterial community composition and species richness along the BSF life cycle, and identified nine prevalent core microbiota. The study also inferred 27 potential metabolic pathways differentially used among the BSF life cycle. This research provides a better understanding of metabolic processes during BSF development and their implications for bio-waste processing.

Summary: In this study, a large-scale in silico search was conducted to identify putative tRNA genes in baculovirus genomes. The analysis revealed diverse tRNA genes with variations in structure, location, and anti-codon identity. Some genes showed a bias for the codons specified by the tRNAs present in their genomes. Additionally, evidence of transcription and modification of viral tRNA genes was found through analysis of small RNA deep sequencing data. Further research is required to understand the expression and functionality of these viral tRNAs.

Summary: This article reports on changes to virus taxonomy and nomenclature approved by the International Committee on Taxonomy of Viruses (ICTV) in April 2023. All ICTV members were invited to vote on 174 taxonomic proposals and a revision of the ICTV Statutes that had been approved by the ICTV Executive Committee in July 2022. Majority approval was obtained for all proposals and the revised ICTV Statutes. A significant change was the renaming of existing species according to the binomial format and the classification of gene transfer agents (GTAs) as viriforms. In total, one class, seven orders, 31 families, 214 genera, and 858 species were created.

Summary: Viruses of four families of arthropod-specific large dsDNA viruses possess homologs of genes involved in the baculovirus primary infection mechanism, suggesting a common origin. The class Naldaviricetes and the order Lefavirales were recently established to accommodate these viruses and their shared characteristics. A system for binomial naming of virus species in the order Lefavirales was also established, following a decision by the ICTV to standardize virus nomenclature.

Summary: The spongy moth virus Lymantria dispar iflavirus 1 (LdIV1) was found in female moths from both the USA and China populations. The genomes of LdIV1 variants were compared and divided into clades based on the geographic origin of their hosts. The presence of LdIV1 RNA was detected at high levels in all samples, showing a wide range of LdIV1 reads in the sequenced volume.
