The gut microbiome is well known to impact host physiology and health. Given widespread control of by circadian clocks, we asked how the interacts with rhythms in Drosophila gut. did not cycle flies fed ad libitum, timed feeding (TF) drove limited cycling only clockless per01 flies. However, TF loss influenced composition transcriptome, independently together. Moreover, both interventions increased amplitude rhythmic gene expression, effects at least partly due changes histone acetylation....
Vitellogenin (Vg) is a well-known nutritious protein involved in reproduction nearly all oviparous animals, including insects. Recently, Vg has been detected saliva proteomes of several piercing-sucking herbivorous arthropods, the small brown planthopper (Laodelphax striatellus, SBPH). Its function, however, remains unexplored. We investigated molecular mechanism underlying SBPH orally secreted Vg-mediated manipulation plant-insect interaction by RNA interference, phytohormone and H2 O2...
Abstract BACKGROUND: Laodelphax striatellus (Fallén) is a major pest of cultivated rice and commonly controlled in China with the organophosphate insecticides. To develop better resistance management strategy, chlorpyrifos‐resistant strain L. was selected laboratory, its cross‐resistance to other insecticides possible mechanisms chlorpyrifos were investigated. RESULTS: After 25 generations selection chlorpyrifos, developed 188‐fold comparison susceptible strain, showed 14‐ 1.6‐fold...
The small brown planthopper ( Laodelphax striatellus ; SBPH) is a piercing-sucking insect that secretes salivary proteins into its plant host during feeding. However, the mechanisms by which these regulate defense responses remain poorly understood. Here, we identified disulfide isomerase (LsPDI1) in SBPH proteome. LsPDI1 was highly expressed glands and secreted rice plants Transient planta expression absence of signal peptide induced reactive oxygen species (ROS) burst, cell death, callose...
The striped stem borer (Chilo suppressalis, SSB) is a highly destructive insect pest in rice (Oryza sativa). SSB oral secretions (OSs) can induce plant defense responses rice. However, the specific effectors OSs that mediate these interactions with remain poorly understood. In this study, hallmarks of ferroptosis-like response, such as reprogramming ferroptosis-related genes, reduced glutathione levels, accumulation ferric ion, and enhanced lipid peroxidation by reactive oxygen species...
Abstract Plants activate defense machinery when infested by herbivorous insects but avoid such costs in the absence of herbivory. However, key signaling pathway regulators underlying flexibility and mechanisms that exploit these components to disarm plant systems remain elusive. Here, it is reported immune repressor 14‐3‐3e rice Oryza sativa (OsGF14e) regulates homeostasis. Infestation with brown planthopper (BPH) Nilaparvata lugens decreased OsGF14e expression; however, level downregulation...
Herbivore-associated molecular patterns (HAMPs) in saliva enable plants to detect herbivores and activate pattern-triggered immunity (PTI). Piercing-sucking secrete gel saliva, forming salivary sheaths that assist feeding, however, the role of proteins within these modulation plant defenses remains poorly understood. Here, a thermostable HAMP, myosin light chain 1-like (myosin) is identified, from sheath small brown planthopper (SBPH) Laodelphax striatellus. Myosin widely conserved arthropod...
Abstract Damage caused by the rice striped stem borer (SSB), Chilo suppressalis (Walker) (Lepidoptera: Pyralidae), is much more severe on indica / xian than japonica geng ( Oryza sativa ) which matches pest outbreak data in cropping regions of China. The mechanistic basis this difference among subspecies remains unclear. Using transcriptomic, metabolomic and genetic analyses combination with insect bioassay experiments, we showed that utilise different defence responses to repel SSB, SSB...
Abstract BACKGROUND Calcium (Ca 2+ )‐binding proteins in the saliva of herbivorous insects function as effectors to attenuate host plant defenses and thus improve insect feeding performance. Silencing these genes via transgenic plant‐mediated RNAi is a promising pest control strategy. However, their sequences functions small brown planthopper Laodelphax striatellus (SBPH) remain be investigated. RESULTS We identified putative EF‐hand Ca ‐binding protein (LsECP1) SBPH watery saliva. LsECP1...
Abstract BACKGROUND Halotydeus destructor is a major pest of crops and pastures across southern parts Australia. This invasive mite has been chemically controlled for over 50 years, but resistance to synthetic pyrethroids organophosphates developing. Understanding processes behind the emerging important effective management efforts. We undertook ddRAD pool‐sequencing approach analyse genome‐wide single nucleotide polymorphism variation in H. population samples at two scales: local set...
The brown planthopper (Nilaparvata lugens, BPH) and small (Laodelphax striatellus, SBPH) are major pests of rice (Oryza sativa) in Asia. These piercing-sucking insects secrete saliva into the host during feeding. Nevertheless, it is largely unknown how planthoppers use salivary effectors to enable continuous feeding on rice. Here, we screened their proteomes selected eight proteins conserved between SBPH BPH as candidate effectors. Silencing calmodulin (CaM) impeded from penetrating phloem....
Abstract N 6 ‐methyladenosine (m A) is the most prevalent modification in cellular RNA which orchestrates diverse physiological and pathological processes during stress response. However, differential m A modifications that cope with herbivore resistant susceptible crop varieties remain unclear. Here, we found rice stem borer (RSB) larvae grew better on indica (e.g., MH63, IR64, Nanjing 11) than japonica Nipponbare, Zhonghua 11, Xiushui 11). Then, transcriptome‐wide profiling of...
Abstract BACKGROUND N 6 ‐Methyladenosine (m A) is a common messenger RNA (mRNA) modification that affects various physiological processes in stress responses. However, the role of m A modifications plants responses to herbivore remains unclear. RESULTS Here, we found an infestation brown planthopper ( Nilaparvata lugens ) female adults enhanced resistance rice N. . The methylome analysis ‐infested and uninfested samples was performed explore interaction between methylation mainly occurred...
The female-biased infection of facultative symbionts has been found in Bemisia tabaci; however, whether there are any differences tomato yellow leaf curl virus (TYLCV) and obligate symbiont rates between females males is unknown. Determining such exist would be very important for understanding the spread plant symbionts. We compared both types, including symbionts, TYLCV sexes five field populations from Jiangsu Province, China. Portiera aleyrodidarum was not every whitefly tested. In all...
Abstract The whitebacked planthopper, S ogatella furcifera ( H orváth) emiptera: D elphacidae), an economically important rice pest, has developed resistance to many insecticides. Cycloxaprid, a novel cis ‐nitromethylene neonicotinoid insecticide, good industrialization prospects because of its high efficiency against planthoppers, including imidacloprid‐resistant populations. This study focused on the genes involved in xenobiotic detoxification and stress reaction after exposure doses...
