“…Some viruses even change from parasitic to mutualistic with a change in environmental conditions (González et al ., 2021 ). The protective effect of plant viruses is mainly observed for drought (Mishra et al ., 2021 ), but some studies also report that viruses can have a positive effect on plant responses to (other) abiotic stresses, such as high temperature (Anfoka et al ., 2016 ) or salt stress (Sinha et al ., 2021 ). To our knowledge this is the first example of a comovirus exerting such a positive effect.…”

1) Transcriptome studies of Illumina RNA-seq datasets of different Arabidopsis thaliana natural accessions and T-DNA mutants revealed the presence of two virus-like RNA sequences which showed the typical two segmented genome characteristics of a comovirus.(2) This comovirus did not induce any visible symptoms in infected Arabidopsis plants cultivated under standard laboratory conditions. Hence it was named Arabidopsis latent virus 1 (ArLV1). Virus infectivity in Arabidopsis plants was confirmed by RT-qPCR, transmission electron microscopy and mechanical inoculation. ArLV1 can also mechanically infect Nicotiana benthamiana, causing distinct mosaic symptoms.(3) A bioinformatics investigation of Arabidopsis RNA-Seq repositories, including nearly 6500 Sequence Read Archives (SRAs) in the NCBI SRA database, revealed the presence of ArLV1 in 25% of all archived natural Arabidopsis accessions and in 8.5% of all analyzed SRAs. ArLV1 could also be detected in Arabidopsis plants collected from the wild.(4) ArLV1 is highly seed-transmissible with up to 40% incidence on the progeny derived from infected Arabidopsis plants. This has likely led to a worldwide distribution in the model plant Arabidopsis with yet unknown effects on plant performance in a substantial number of studies.

“…have been described as having an effect on the course of plant virus infection. These environmental stressors change the plantvirus interaction by inhibiting plant host defense responses and promoting plant susceptibility to viruses, which in turn aids viral infection and symptom development although reverse effects have also been observed (147)(148)(149)(150)(151)(152)(153)(154)(155)(156)(157)(158)(159)(160). Effects of certain abiotic stressors on plant virus infection are becoming increasingly important in the wake of climate change, in particular, temperature increase (161).…”

Viruses are highly evolvable biological entities capable of wreaking havoc on our society. Therefore, a better understanding of virus evolution is important for two main reasons: (i) it will lead to better management of current diseases and prevention of future ones, and (ii) it will contribute to a better understanding of evolutionary processes and their dynamics. In order to understand the evolution of viruses as a whole, it is necessary to consider different elements that shape virus evolution. In this review, we give a general overview of the most relevant factors that determine the evolution of plant viruses. We will focus on mutation rates, epistasis, robustness, recombination, genome organization, virus-host interactions, transmission, community interactions and abiotic factors. Since this review gives a summarized overview of the most important factors in virus evolution it can be a useful starting material for anyone interested in approaching (plant) virus evolution.

“…[90] The two segments of the FHV genome are referred to as RNA 1 (3.1 kb) and RNA 2 (1.4 kb). [91] RNA 1 encodes the catalytic subunit of RNAdependent RNA polymerase (RdRp), protein A, while RNA 2 FHV peptide absorption is decreased when it interacts with glycosaminoglycans.

The rapid advancement of nanotechnology in recent years has opened new avenues of investigation for biomedical sciences. Viral nanoparticles (VNPs) are formulated from plant viruses, mammalian viruses, or bacteriophages. Based on their structure, viruses, and synthetic carriers have been utilized to design bio‐inspired nanocarriers, which serve as building blocks for innovative therapeutic applications. Scientists can chemically or genetically engineer VNPs to encompass various properties, such as enhancing their functionalization with therapeutic molecules and imaging reagents, enabling targeted delivery to specific ligands. The implementation of these novel nanocarrier platforms can revolutionize treatments for cancer, infectious diseases, and chronic illnesses. The primary goal of drug delivery systems is to localize cargo to the specific target site, increasing therapeutic benefits and minimizing off‐target effects. This review critically evaluates the major virus species used as nanocarriers, their applications in therapeutics, and their advantages and disadvantages.
