“…Plant viruses have a complex mutualistic relationship with their vector insects. They can persist within their vectors for a long time and achieve long-lasting transmission by regulating the interactions between their pathogenicity and proliferation [ 33 , 35 ]. Most studies of immune interactions between rice viruses and vector insects are mainly focused on Laodelphax striatellus and its transmitted rice viruses, such as the rice stripe virus (RSV) [ 36 , 38 , 39 ].…”

“…In humoral immunity, when pathogens were recognized by pattern recognition receptors (PRRs), the relevant signaling pathways were triggered including Toll, Immune deficiency (Imd), Janus kinase/signal transducers and activators of transcription (JAK/STAT), Prophenoloxidase (PPO), and RNA interference (RNAi) pathways. The antimicrobial substances were then released to attack the harmful pathogens [ 22 , 33 ]. Plant viruses, like other foreign pathogens in the insect system, can trigger the immune response of their host insect vector [ 13 , 32 ].…”

“…Yoshikawa et al [ 34 ] reported that both BPH-transmitted viruses (RRSV and RGSV) caused changes in the activity of detoxification enzymes, but at different degrees for different viruses, sexes, and resistant strains. Plant viruses can persist in vector insects, and they co-evolve in more intricate interactions with vector insects [ 33 , 35 , 36 ]. They can manipulate the host’s immune response by weighing their pathogenicity and proliferation, enabling long-term existence in the vectors [ 33 , 36 ].…”

“…Plant viruses and EPF could co-exist in hosts where both have complex immune interactions with vector insects [ 22 , 33 , 35 ]. It is therefore important to understand whether RRSV invasion could affect the lethality of the entomopathogenic fungus M. anisopliae YTTR and the immune interactions between M. anisopliae YTTR and BPH.…”

Plant viruses and entomopathogenic fungi (EPF) can both elicit immune responses in insects. This study was designed to clarify whether plant viruses could affect the efficacy of EPF and explore the immune responses of brown planthopper (BPH), Nilaparvata lugens, in response to different pathogen infections. In this study, a strain of Metarhizium anisopliae YTTR with high pathogenicity against BPH was selected and explored whether rice ragged stunt virus (RRSV) could affect its lethality against BPH. RNA-seq was used to detect the inner responses of BPH in response to RRSV and M. anisopliae YTTR infection. Results showed that M. anisopliae YTTR has strong lethality against BPH (RRSV-carrying and RRSV-free). RRSV invasion did not affect the susceptibility of BPH against M. anisopliae YTTR at all concentrations. At 1 × 108 spores/mL, M. anisopliae YTTR caused a cumulative mortality of 80% to BPH at 7 days post-treatment. The largest numbers of differentially expressed genes (DEGs) was obtained in BPH treated with the two pathogens than in other single pathogen treatment. In addition, KEGG enrichment analysis showed that the DEGs were mostly enriched in immune and physiological mechanisms-related pathways. Both RRSV and M. anisopliae YTTR could induce the expression changes of immune-related genes. However, most of the immune genes had varying expression patterns in different treatment. Our findings demonstrated that RRSV invasion did not have any significant effect on the pathogenicity of M. anisopliae YTTR, while the co-infection of M. anisopliae YTTR and RRSV induced more immune and physiological mechanisms -related genes’ responses. In addition, the presence of RRSV could render the interplay between BPH and M. anisopliae YTTR more intricate. These findings laid a basis for further elucidating the immune response mechanisms of RRSV-mediated BPH to M. anisopliae infection.

BackgroundPrevious studies of brown planthopper (BPH), Nilaparvata lugens, showed that carrying the plant pathogenic virus, rice ragged stunt virus (RRSV), enhanced the lethality of the entomopathogenic fungus, Metarhizium anisopliae (YTTR). The underlying mechanism for this was not established but a serine protease cascade was hypothesized to be involved.ResultsTwo immune response genes, NlKPI and NlVenomase, were identified and shown to be involved. Synthesized dsRNA techniques used in this study to explore gene function revealed that treatment with dsRNA to silence either gene led to a higher BPH mortality from M. anisopliae infection than the dsRNA control treatment. NlKPI and NlVenomase play vital roles in BPH immunity to defend against alien pathogens. And both genes participate in the immune response process of BPHs against co‐infection with RRSV and M. anisopliae YTTR by regulating the expression of antimicrobial peptides and phenoloxidase activity.ConclusionOur study provided new targets for BPH biocontrol and laid a solid foundation for further research on the interaction of “plant virus‐ insect vector‐ entomopathogenic fungus”.This article is protected by copyright.
