Host-Dependent Cytopathological Responses to Beet Curly Top Virus Infection in Four Plant Species · 2026 · DOIFuture research should focus on expanding the dataset with additional global isolates, integrating biological and epidemiological data and exploring the evolutionary dynamics of other genomic regions to further improve our understanding of PVS diversity, adaptation and host–virus interactions.
RNA-dependent RNA polymerase domain-based molecular characterisation and evolutionary analysis of potato virus S · 2026 · DOIIt remains unclear to what extent DNA aptamer bound to PSTVd persists within host cells following inoculation. Therefore, further investigation is warranted, including the possibility that multiple molecules may form complexes and bind more stably.
DNA aptamers selected against potato spindle tuber viroid bind the viroid and differentially modulate infection · 2026 · DOIThough some host cellular factors have been identified, their precise function in viral pathogenesis remains elusive. Gaining insights into these aspects is essential to devising durable resistance strategies beyond R-gene-based approaches. Additionally, the way in which several viruses are transmitted remains largely unclear.
The Evolving Landscapes of Invisible Invaders: Global Insights on Plant Viruses and Vector Complexes · 2026 · DOIHowever, the effectiveness of dsRNA-induced PTI against viruses from diverse taxa, its impact on different stages of the infection, as well as effectors used by viruses other than tobamoviruses to counteract this defense response remain poorly explored.

Phylodynamic of Tomato Brown Rugose Fruit Virus and Tomato Chlorosis Virus, Two Emergent Viruses in Mixed Infections in Argentina · 2025 · DOIFurther investigation is needed to confirm these findings and to evaluate the effects of these viruses on sweetpotato yield, tuber quality, and susceptibility to other pathogens. More broadly, this work highlights the importance of proactive surveillance and robust diagnostics for emerging viruses in underexplored regions like Sub-Saharan Africa.
Insights into Novel Viral Threats in Sweetpotato from Burkina Faso: Characterisation of Unexplored Pathogens · 2025 · DOIIn light of the above considerations, the development of RNAi-based fungicides will require further studies to achieve broad applicability, and in the meantime, it is desirable to progress on the validation of other unconventional strategies such as autophagy, defence priming, nanomaterials, hormonal treatments, amino acids, and antimicrobial peptides.
Challenges and Opportunities Arising from Host–Botrytis cinerea Interactions to Outline Novel and Sustainable Control Strategies: The Key Role of RNA Interference · 2024 · DOIThere is a lack of understanding of the current prevalence, genetic diversity, and evolutionary dynamics of DuCV in Korea. The study aims to fill this gap by investigating the prevalence and genetic characteristics of DuCV in Korea. The research gap includes the need for effective control strategies and understanding of the global epidemiology of the virus.
Epidemiological Investigation and Genetic Analysis of Duck Circovirus in Korea from 2013 to 2022 · 2024 · DOIThere is a lack of understanding of the mechanisms underlying chitosan-induced plant resistance to plant viruses. The paper identifies a need for innovative and environmentally friendly materials that can be applied in agriculture for plant protection against various pathogens.
The host factors responsible for the intra- and inter-cellular movement of viroids remain highly incomplete. The understanding of the structural and molecular mechanisms that mediate directional RNA trafficking is limited. The identification of viroid-like RNAs is predominantly based on computer-based predictions, and their ability to infect hosts and life cycles need to be tested.
Incorporating intracellular processes can improve parameter estimates and guide therapeutics. There is a need for increased data collection at a finer scale of resolution to validate complex models.
The lack of theoretical support for key harvesting components. The high damage rate of existing pod pepper harvesters. The need for a comprehensive study on the damage mechanism of collisions between pod pepper and comb fingers.
Nano-enabled RNAi offers a potential to move citrus antiviral control from short-lived, reactive measure toward programmable, sequence-specific protection that can be deployed against multiple viruses and importantly against key vectors.
TMV has been at the forefront of plant virus research, studying mechanisms of disassembly, replication, and intra- and intercellular movement (e.g.,). While some advances in early cell biological and biochemical studies were made decades ago, they are still relevant and fundamental.
Tobacco Mosaic Virus Movement: From Capsid Disassembly to Transport Through Plasmodesmata · 2025 · DOIThe viral proteins linked to the genome (VPg), including the longer ones of the human, animal and plant viruses, will be a source of research for many years to come. Their potential for antiviral drug design is only beginning to be explored.
The data obtained in this study indicates some key regions and mutations of the eIF4E gene associated with cowpea resistance to CABMV. As future perspectives, the target regions may be promising for gene editing approaches, such as CRISPR/Cas9.
Deciphering Cowpea Resistance to Potyvirus: Assessment of eIF4E Gene Mutations and Their Impact on the eIF4E-VPg Protein Interaction · 2025 · DOISpecies demarcation criteria for ULVs have not yet been established, but according to the currently accepted criteria for the genus Umbravirus (nt identity < 70%), together with differences in genome…
