The brown planthopper, Nilaparvata lugens, the most destructive pest of rice, is a typical monophagous herbivore that feeds exclusively on rice sap, which migrates over long distances. Outbreaks it have re-occurred approximately every three years in Asia. It has also been used as model system for ecological studies and developing effective management. To better understand how sap-sucking arthropod adapted to its exclusive host selection provide insights improve control, we analyzed genomes...
Abstract Salivary elicitors secreted by herbivorous insects can be perceived host plants to trigger plant immunity. However, how secrete other salivary components subsequently attenuate the elicitor-induced immunity remains poorly understood. Here, we study small brown planthopper, Laodelphax striatellus sheath protein LsSP1. Using Y2H, BiFC and LUC assays, show that LsSP1 is into binds via mucin-like (LsMLP). Rice pre-infested with ds LsSP1- treated L. are less attractive nymphs than those...
Most phloem-feeding insects secrete gelling and watery saliva during the feeding process. However, functions of salivary proteins are poorly understood. In this study, our purpose was to reveal components in a rice sap-sucking insect pest, Nilaparvata lugens. The accomplishment whole genome transcriptome sequencing N. lugens would be helpful for elucidating gene information expression specificity proteins. we have, first time, identified abundant protein from monophagous species through...
Summary Soybean staygreen syndrome, characterized by delayed leaf and stem senescence, abnormal pods, aborted seeds, has recently become a serious prominent problem in soybean production. Although the pest Riptortus pedestris received increasing attention as possible cause of mechanism remains unknown. Here, we clarify that direct feeding R. , not transmission pathogen this pest, is primary typical syndrome critical damage occurs at early pod stage . Transcriptome profiling indicated many...
Communication between insects and plants relies on the exchange of bioactive molecules that traverse species interface. Although proteinic effectors have been extensively studied, our knowledge other involved in this process remains limited. In study, we investigate role salivary microRNAs (miRNAs) from rice planthopper Nilaparvata lugens suppressing plant immunity. A total three miRNAs were confirmed to be secreted into host during insect feeding. Notably, sequence-conserved miR-7-5P is...
Abstract Herbivorous insects employ an array of salivary proteins to aid feeding. However, the mechanisms behind recruitment and evolution these genes mediate plant-insect interactions remain poorly understood. Here, we report a potential horizontal gene transfer (HGT) event from bacteria ancestral bug Eutrichophora. The acquired subsequently underwent duplications evolved through co-option. We annotated them as horizontal-transferred, Eutrichophora-specific protein (HESPs) according their...
Abstract The brown planthopper ( Nilaparvata lugens , BPH ), white‐backed Sogatella furcifera WBPH ) and small Laodelphax striatellus SBPH are important rice pests in Asia. These three species differ thermal tolerance exhibit quite different migration overwintering strategies. To understand the underlying mechanisms, we sequenced compared transcriptome of under temperature treatments. We found that metabolism‐, exoskeleton‐ chemosensory‐related genes were modulated. In high (37 °C), heat...
Abstract Most plant viruses that seriously damage agricultural crops are transmitted by insects. However, the mechanisms enabling virus transmission insect vectors poorly understood. The brown planthopper ( Nilaparvata lugens ) is one of most serious rice pests, causing extensive to plants sucking phloem sap and transmitting viruses, including Rice ragged stunt (RRSV). In this study, we investigated RRSV from its vector in vivo using terminal deoxynucleotidyl transferase dUTP nick-end...
Extracellular DNA, released by damaged plant cells, acts as a damage-associated molecular pattern (DAMP). We demonstrated previously that the small brown planthopper (Laodelphax striatellus, SBPH) secreted DNase II when feeding on artificial diets. However, function of in insect remained elusive. The influences SBPHs and rice plants were investigated suppressing expression or application heterogeneously expressed II. is mainly salivary gland responsible for DNA-degrading activity saliva....
Abstract The whitefly Bemisia tabaci is a notorious agricultural pest of many crops worldwide. Although it thought that B. secretes saliva into the host plant to counter defenses, knowledge on salivary proteome limited. Here, we characterized gene/protein repertoires glands and secreted by transcriptomic liquid chromatography tandem mass spectroscopy analyses. A total 698 gland‐enriched unigenes 171 proteins were identified. Comparative analysis between those different arthropod species...
Significance To accomplish the infection cycle, plant viruses usually employ various pathogenic factors to inhibit host antiviral defense. Revealing mechanisms conserved among different is essential for developing broad-spectrum disease control. Here, we show that a class of independently evolved transcriptional repressors widely present in viruses. Despite diverse sequences and evolutionary origins, these all modulate JA signaling by inhibiting activation OsMYC transcription factors,...
Many insect pests, including the brown planthopper (BPH), undergo windborne migration that is challenging to observe and track. It remains controversial about their patterns largely unknown regarding underlying genetic basis. By analyzing 360 whole genomes from around globe, we clarify sources of worldwide BPHs illuminate a landscape BPH showing East Asian populations perform closed-circuit journeys between Indochina Far East, while Malay Archipelago South Asia one-way Indochina. We further...
Wolbachia in host germ lines are essential for their vertical transmission to the next generation. It is unclear how regulation of oocyte development influences location and mechanistic basis transmission. Here, we investigated whether vitellogenin Laodelphax striatellus. increased density spread from anterior tropharium developing oocytes as ovaries developed. Microscopic observations indicated that invaded ovarioles its side rather than pedicel side. utilized Vg transovarial transportation...
Abstract A large number of insect-specific viruses (ISVs) have recently been discovered, mostly from hematophagous insect vectors because their medical importance, but little attention has paid to important plant virus such as the whitefly Bemisia tabaci , which exists a complex cryptic species. Public SRA datasets B. and newly generated transcriptomes three Chinese populations are here comprehensively investigated characterize viromes different Twenty novel ISVs were confidently identified,...
The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway is an evolutionarily conserved signaling that can regulate various biological processes. However, the role JAK-STAT in persistent viral infection insect vectors has rarely been investigated. Here, using a system comprised two different plant viruses, Rice stripe virus (RSV) black-streaked dwarf (RBSDV), as well their vector small brown planthopper, we elucidated regulatory mechanism infection. Both RSV RBSDV...
Abstract Shading is widely used in tea cultivation to improve quality by modulating various metabolic pathways plants. However, the differential sensitivity of specific metabolites and cultivar‐dependent responses shading are not yet fully understood. This study examined impact on chemical composition transcriptional profiles cv. Longjing 43 Yabukita. Among main quality‐related compounds, flavonol glycosides were highly responsive shading, while catechins displayed distinct cultivar‐specific...
Phloem-feeding insects present significant economic threats worldwide and remain challenging to understand due their specialized feeding strategies. Significant advances in genetics, genomics, biochemistry have greatly enriched our comprehension of phloem–insect interactions. However, existing studies relying on two-dimensional discrete images limited understanding visible morphological details. In this study, we leverage volume electron microscopy (vEM) technology unveil a...
