Summary: This study found that TbCSV-derived vsiRNA18 (TvsiRNA18) can regulate TbCSV infection in Nicotiana benthamiana plants. TvsiRNA18 aggravates disease symptoms and enhances viral DNA accumulation by suppressing ATP-dependent RNA helicase (ATP-dRH) expression. This is the first report to demonstrate that TbCSV-derived vsiRNA can target host endogenous genes to affect symptom development.

Summary: In this study, four full-length infectious clones representing the causal agents of tobacco bushy top disease (TBTD) were constructed. These causal agents were found to induce typical TBTD symptoms in tobacco and Nicotiana benthamiana plants. Moreover, one of the causal agents, TBTV, was able to cause necrosis on its own. The results indicated that one of the causal agents, TVDVaRNA-YK, could increase the accumulation of other causal agents in infected plants, while TBTVsatRNA-YK increased the efficiency of aphid transmission for TBTV and TVDV.

Summary: As obligate intracellular parasites, plant viruses induce significant changes in host cells, leading to the development of symptoms and causing substantial economic losses in agricultural and horticultural crops. However, existing literature lacks a clear presentation of the mechanisms underlying plant virus-induced symptoms. To address this, a comprehensive review was conducted to highlight the crucial interactions between plant viruses and host factors, discussing key genes that increase viral virulence and their roles in influencing cellular processes critical for symptom development. The review also explores the alterations in host metabolism and gene expression associated with virus-induced symptoms, as well as the influence of environmental factors on symptom development.

Summary: In this study, a novel SARS-CoV-2 viral vector was developed, allowing for investigation by the broader scientific community. The vector transduces target cells in an ACE2-dependent manner, and the incorporation of the VEEV self-amplification mechanism increases gene expression level and extends transgene expression time. Furthermore, the vector has significant applications in neutralizing antibody quantification and antiviral drug testing.

Summary: The aromatic ring in W-122 in the core domain of potyviral CP is critical for cell-to-cell movement by affecting CP stability and viral replication. Mutations in W-122 significantly reduce CP accumulation levels, impairing virus cell-to-cell movement. Substitution of W-122 with different aromatic residues allows mutant viruses to move systemically and accumulate to levels similar to wild-type viruses.

Summary: Research has shown that the ESR1 gene interacts with genes related to WUS and STM, affecting their phenotypes in plant lateral organ development. The ESR2 gene can partially suppress the phenotype of the STM gene in the later nutritional stage, and this complex genetic interaction is related to the different expression patterns of ESR genes.

Summary: NSP14 is a dual function enzyme, consisting of an N-terminal exonuclease domain (ExoN) and a C-terminal guanine-N7-methyltransferase (N7-MTase) domain. The interaction between NSP14 and NSP10 enhances the nuclease activity. Structural analysis reveals conformational changes in the NSP14 ExoN domain upon binding of NSP10, which explains the stimulation of nuclease activity. Additionally, structural insights into the viral mRNA capping process are gained through the structure of NSP14 in complex with cap analogue (7Me)GpppG.

Summary: RNA viruses rely on cellular RNA-binding proteins to facilitate replication and spread, with a pool of RBPs typically incorporated into viral particles. These RBPs play crucial roles in viral particle formation and infectivity, suggesting broader implications for host RBPs in virus infection than previously thought.

Summary: This study found that the transcription level of ovine ISG15 (oISG15) is upregulated in a time-dependent and BTV multiplicity of infection-dependent manner. Overexpression of oISG15 enhances BTV replication, while knockdown of endogenous oISG15 inhibits BTV replication. The interaction between BTV viral proteins and oISG15 was identified, and oISG15 overexpression was found to stabilize VP4 and NS1 proteins and interfere with the degradation of NS1 via the autophagy pathway.

Summary: The integrated stress response (ISR) is activated in response to SARS-CoV-2 infection, triggering translational arrest and inhibiting stress granule formation. However, the stress-responsive transcription factors ATF4 and CHOP are not induced. Different SARS-CoV-2 variants show variant-specific differences in ISR activation, suggesting potential impacts on pathogenesis and treatment strategies.

Summary: Coxsackievirus A6 (CVA6) has emerged as an important agent causing hand, foot, and mouth disease (HFMD). Mutations in residue 64 of the virus have been found to increase resistance to ribavirin and decrease sensitivity to guanidine hydrochloride. This mutation also leads to increased replication fidelity and reduced pathogenicity. These findings provide a foundation for the development of a safe and effective live attenuated CVA6 vaccine.

Summary: Rotavirus is a major cause of viral gastroenteritis in infants and continues to be a severe issue in underdeveloped nations. Recent research has shown that a long non-coding RNA called SLC7A11-AS1 is upregulated during rotavirus infection and plays a role in facilitating the virus's propagation by regulating intracellular glutathione and lipid peroxidation.

Summary: Bat-borne emerging viruses, such as the Ebola virus and Nipah virus, pose a significant threat to public health. In this study, we identified micafungin as a potential antiviral drug against Pteropine orthoreovirus (PRV) and found that it inhibits viral release in human cells through activating the endoplasmic reticulum stress response pathway. This research provides valuable insights into the development of effective treatments for future virus pandemics.

Summary: This study reports the construction and validation of an infectious cDNA clone of Citrus leprosis virus C (CiLV-C) based on an agroinfection system. Agro-injected Nicotiana benthamiana plants showed localized lesions similar to the natural infection process. The virus recovered from the infected plant tissue could be mechanically transmitted between plants. The CiLV-C reverse genetic system provides a powerful molecular tool for unraveling the peculiarities of the citrus leprosis pathosystem.

Summary: This study found that the Omicron variant has different replication characteristics compared to other variants of concern, being able to efficiently produce infectious virus in nasal cells but not lung cells. In addition, the Delta and Omicron variants showed increased infection efficiency in A549 cells. These findings suggest that the variants of concern have better adaptation to humans but do not have an extended host range.

Summary: Genomic surveillance in Senegal since March 2020 has detected the emergence of Omicron BA.4 and BA.5 sublineages in June 2022. Next-generation sequencing and phylogeny analysis of isolates from a cluster of cases in Northern Senegal in July 2022 revealed that the BA.4 cases originated from a XAS recombinant, marking the first reported sequence of this variant from Senegal. Continuous genomic surveillance of positive SARS-CoV-2 samples is crucial.
