Plant viruses are responsible for nearly 47 % of all crop losses brought by plant diseases, which have a considerable negative impact on agricultural output. Nanoparticles have the potential to greatly raise agricultural output due to their wonderful applications in the fields of highly sensitive biomolecular detection, disease diagnostics, antimicrobials, and therapeutic compounds. The application of nanotechnology in plant virology is known as nanophytovirology, and it involves biostimulation, drug transport, genetic manipulation, therapeutic agents, and induction of plant defenses. The inactivation and denaturation of capsid protein, nucleic acids (RNA or DNA), and other protein constituents are involved in the underlying mechanism. To determine the precise mechanism by which nanoparticles affect viral mobility, reproduction, encapsidation, and transmission, more research is however required. Nanoparticles can be used to precisely detect plant viruses using nanobiosensors or as biostimulants. The varieties of nanoparticles employed in plant virus control and their methods of virus suppression are highlighted in this review.

Plant viruses are known to indirectly manipulate insect vector behavior by altering host-plant phenotypes, yet the mechanisms by which they directly regulate vector behavior to enhance transmission remain poorly understood. Here, we reveal how the southern rice black-streaked dwarf virus (SRBSDV) reprograms the host preference of its planthopper vector, Sogatella furcifera, from infected to healthy rice plants by disrupting immune-olfactory crosstalk. We demonstrate that the SRBSDV-encoded P8 protein competitively binds to the S.

Mounting evidence indicates that viruses exploit elevated reactive oxygen species (ROS) levels to promote replication and pathogenesis, yet the mechanistic underpinnings of this viral strategy remain elusive for many viral systems. This study uncovers a sophisticated viral counter-defense mechanism in the Cryphonectria hypovirus 1 (CHV1)-Fusarium graminearum system, where the viral p29 protein subverts host redox homeostasis to overcome antiviral responses. That p29 directly interacts with and inhibits the enzymatic activity of fungal NAD(P)H-dependent FMN reductase 1 (FMR1), leading to increased ROS accumulation and subsequent autophagy activation is demonstrated.

The utilization of arbuscular mycorrhizal fungi (AMF) and spp. correlates with improved plant nutrition and the stimulation of systemic plant defenses in response to pathogen challenges. Nonetheless, studies examining the effects of AMF colonization and the foliar application of the isolate Tvd44 on viral infection are limited.

Superinfection exclusion (SIE) is a finely tuned virus-virus interaction mechanism closely linked to the viral infection cycle. However, the mechanistic basis of SIE remains incompletely understood in plant viruses, particularly among negative-sense, single-stranded RNA viruses. In this study, we first describe the development of an efficient reverse genetics system for the plant nucleorhabdovirus Physostegia chlorotic mottle virus (PhCMoV) by codon optimisation of the large polymerase coding sequence.

The extensive use of highly toxic and residual pesticides has a significant negative impact on agricultural production and the ecological environment. The development of new green antiviral agents has become a major demand for ensuring the development of green ecological agriculture. Indole alkaloids are widely present in nature and have diverse biological activities.
