Summary: Vector-borne plant pathogens manipulate host traits and vector behavior to facilitate their spread, while infection by opportunistic fungi does not require vectors but may be facilitated by herbivore damage. This study demonstrates that a fungus can attract insect herbivores through volatile emissions, leading to vertical transmission and cycle continuation. The fungus manipulates both host plant and insect herbivore across life cycle to promote its infection and dissemination.

Summary: Invertebrate pests in rice fields are a natural reservoir of diverse RNA viruses, and host taxonomy and geographical location play important roles in shaping viral diversity. The discovery of new and known RNA viruses in this study provides valuable information for developing efficient strategies to manage insect pests and virus-mediated crop diseases.

Summary: The production of raspberry globally averaged 846,515 tons from 2016 to 2020. European red raspberry is the most commonly cultivated variety, but it is susceptible to multiple viruses transmitted by invertebrate vectors. Aphids and nematodes are known vectors of specific raspberry viruses, while other potential vectors need further study. The interactions between vector and non-vector herbivores may promote virus spread.

Summary: Mycoviruses are widespread in the fungal kingdom and are classified into 23 viral families and one genus by the ICTV. Research on mycoviruses has mainly focused on those infecting plant pathogenic fungi, as some have the potential to reduce the virulence of their host and act as biocontrol agents. However, mycoviruses lack extracellular transmission mechanisms and rely on intercellular transmission through hyphal anastomosis, which hinders successful transmission between different fungal strains.

Summary: Viruses in the genus Fijivirus have caused significant damage to crops such as rice, maize, and sugarcane in various countries. Understanding the mechanisms of virus transmission by insect vectors is crucial for managing the spread of virus epidemics. Research needs to focus on the complex interactions among the virus, insect vector, insect microbes, and plants in order to better understand the fijivirus-plant disease system.

Summary: Recent studies have shown that viruses can spread en bloc through extracellular vesicles, especially exosomes, which are lipid bilayer-covered particles. Exosomes, nano-sized particles ranging from 40-200 nm, can carry signaling molecules from donor to acceptor cells, modulating specific signaling reactions in target cells. There are similarities between exosome biogenesis and virus replication, suggesting that viruses can utilize exosome biogenesis to spread and evade immune cells. This review discusses the challenges and opportunities related to the exosomal delivery of viruses in terms of viral infections and public health.

Summary: Plant viruses cause serious threats to agriculture systems by causing devastating diseases. CRISPR/Cas technology has simplified the development of virus-resistant plants, either through manipulation of plant genome or virus genome, and has been used as a solution for plant viral resistance.

Summary: This review provides an overview of transcriptional responses in interactions between plant viruses and insect vectors, focusing on gene expression patterns in different insect groups. Understanding the transcriptional changes in insect vectors induced by viruses can help identify candidate genes for management approaches using RNAi and/or CRISPR editing.

Summary: Plant viruses are pathogens that significantly impact plant growth and crop production. Green pesticides are desirable due to their low resistance and eco-friendliness. Plant immunity agents play a crucial role in enhancing the resilience of the immune system in plants by regulating their metabolism. This paper reviews the antiviral molecular mechanisms, applications, and development of plant immunity agents, such as ningnanmycin, vanisulfane, dufulin, cytosinpeptidemycin, and oligosaccharins, and analyzes the trends and prospects of their use in plant protection.

Summary: Investigating the cross-infection of plant viruses in plant-associated fungi, this study found that various vegetable plants collected from fields in Shandong, China, were infected by multiple plant viruses. High-throughput sequencing revealed the presence of known RNA viruses and novel virus candidates in these plants, with at least 50% of the isolated fungal strains carrying plant viruses.

Summary: This review discusses the interactions between plant single-stranded DNA (ssDNA) viruses and insect transmission systems, including how viruses cross insect cellular barriers, insect responses to virus circulation, and possible viral replication within insects. Despite recent progress in understanding these viruses, many aspects of plant ssDNA virus transmission remain unknown and further research is needed to fully understand the complex virus-insect-plant interactions.

Summary: This study demonstrates that fungal RNA silencing machinery can recognize and process the genome of invading plant viruses. The characteristics of siRNAs in fungi show similarities to those in plants, including size distribution, proportion of plus and minus senses, and nucleotide preference for the 5' termini.
