Oomycetes,commonly known as water molds and phylogenetically belonging to stramenopiles,can infect a wide range of plants and animals,with some members eliciting the most destructive plant diseases and posing severe threats to globalfood security and natural ecosystems(Thines,2018).For example,Phytophthora infestans causes potato late blight and triggered the Irish Famine in the 1840s,and Phytophthora sojae damages soybean production *** resistant cultivars is the most efficient measure for managing the diseases instigated by oomycetes,but the success of the endeavor requires a sound and deep understanding of the molecular basis underlying pathogen-host ***,Sun et al.(2022)elucidated the mechanism underlying the recognition of XEG1,a key virulent effector of ***,by host immune receptor through combining genetic,molecular,and structural approaches,which represents a significant step forward in deeply understanding the infection biology and host immune responses in oomycete diseases.

To protect themselves from infectious diseases,plants have deployed a two-tiered surveillance system to recognize invading pathogens(fu and Dong,2013).In the first layer of the immune system,plants evolved extracellular patter n recognition receptors to detect con served pathoge n-associated molecular patterns(PAM Ps)and activate PAMP-triggered immunity(PTI)(Boiler and Felix,2009).

BACKGROUND： Plant pathogens are responsible for many of history＇s greatest famines. Understanding how plants defend themselves against pathogens is crucial to preventing future famines. Salicylic acid （SA）-mediated plant defense is a key defense pathway, which plants use to defend against biotrophic and hemi-biotrophic pathogens. As a master regulator of SA- mediated plant defense, NPR1 interacts with TGA and WRKY transcription factor families, individual members of which positively or negatively regulate plant defense. OBJECTIVE： In this review we describe the recent developments and predict future directions of research on the involvement of circadian rhythm-, autophagy-, and viral RNA silencing-related genes in SA-mediated plant defense on SA, on plant defense, the induction effects of PR proteins, and the mechanisms by which NPR1 regulates defense-related genes. METHODS： We performed an extensive search of current and past literature using the PubMed, Google Scholar, and Google search engines. Our search terms included：＂SA-mediated plant defense,＂ and ＂NPR1 [AND] salicylic acid.＂ Other search terms, wildcards, and Boolean operators were paired with ＂NPRI＂ or ＂plant defense＂ as needed to research more detailed information related to specific topics covered within this review. We also used Google to search for, ＂economic impact citrus greening,＂＂aspirin,＂＂Irish potato famine,＂ and ＂rice blast,＂ among other terms, to gather background information on the history and impact of plant diseases, and the historical use of aspirin. RESULTS： Of 148 sources found, 132 were directly related to plant defense. The remaining sources are related to the historical and economic impact of plant diseases and the historical use and mechanism of action of aspirin or salicylate. All reviewed sources have been documented in the references section. CONCLUSION： The topic of salicylic acid-mediated plant defense is broad, and new research is expanding our understanding of this topic qui

Aphids are highly destructive pests that greatly hurt the agricultural *** over 40%of plant viruses,they are the most destructive pests that the agricultural industry faces(Gong et al.,2023).Aphids feed on plants,and in doing so,they consume sap from one plant and then move to another and inject their saliva into the new plant(Hooks and Fereres,2006).This cycle causes diseases and viral pathogens to become rampant between plants as the aphids carry viral pathogens from one plant to another and so on.
