“…On one hand, based on this regulatory network, we can cultivate new traits of horticultural plants such as leaf development, flower development, fruit development and disease resistance by changing a certain process ( Chen et al, 2018 ). On the other hand, we can actively promote population control and reduce the prevalence of plant diseases and insect pests through host-induced gene silencing (HIGS), nanoparticle-based exosome delivery of sRNA or spray-induced gene silencing (SIGS; Niu et al, 2021 ). However, there is still a long way to go before sRNA can be used in large-scale agriculture.…”

Small RNAs (sRNAs) encoded by plant genomes have received widespread attention because they can affect multiple biological processes. Different sRNAs that are synthesized in plant cells can move throughout the plants, transport to plant pathogens via extracellular vesicles (EVs), and transfer to mammals via food. Small RNAs function at the target sites through DNA methylation, RNA interference, and translational repression. In this article, we reviewed the systematic processes of sRNA biogenesis, trafficking, and the underlying mechanisms of its functions.

“…This includes strategies to elicit natural plant defenses and immune responses through priming (Worrall et al, 2011), advanced breeding techniques/genetic modification (Bruce, 2012), or plant-or microbe-derived molecules (Wiesel et al, 2014), including plant hormones (De Mesmaeker et al, 2019). One novel approach for eliciting or enhancing plant defenses is through the use of RNA (hostinduced sRNA, dsRNA, or RNAi) for targeted gene silencing in fungal pathogens (Niu et al, 2021). RNA-based crop protection technologies can prevent colonization and infection of crop species by fungal pathogens [e.g., of Sclerotinia sclerotiorum, the causal agent of white stem rot in canola (McLoughlin et al, 2018)] and, in some cases, directly reduce the virulence of fungal pathogens [e.g., of Botrytis cinerea, which causes gray mold (Cai et al, 2018)].…”

Soil health-based agricultural management practices are widely promoted to reduce erosion, increase nutrient use efficiency, improve soil structure, and sustain or increase yields. Pest and disease management are less frequently considered as components of a soil health management system. We present a framework for how the crop protection industry can advance soil health by developing systems of crop protection innovation that simultaneously target soil health outcomes, either through direct impact on soil or by enabling practices that promote soil health outcomes. Such an approach could lead to cross-sectoral, integrated agricultural solutions that achieve agronomic, environmental, and economic goals.

“…Upon pathogen infection, different sizes of pathogen RNA-derived siRNAs are also produced to induce RNAi-based antimicrobial immunity to confer host resistance [10,11]. RNAi-based antiviral defense was first discovered in plants [12,13].…”

Multiple antiviral immunities were developed to defend against viral infection in hosts. RNA interference (RNAi)-based antiviral innate immunity is evolutionarily conserved in eukaryotes and plays a vital role against all types of viruses. During the arms race between the host and virus, many viruses evolve viral suppressors of RNA silencing (VSRs) to inhibit antiviral innate immunity. Here, we reviewed the mechanism at different stages in RNAi-based antiviral innate immunity in plants and the counteractions of various VSRs, mainly upon infection of RNA viruses in model plant Arabidopsis. Some critical challenges in the field were also proposed, and we think that further elucidating conserved antiviral innate immunity may convey a broad spectrum of antiviral strategies to prevent viral diseases in the future.
