Summary Aphids secrete diverse repertoires of salivary effectors into host plant cells to promote infestation by modulating defence. The greenbug Schizaphis graminum is an important cereal aphid worldwide. However, the secreted S. are still uncharacterized. Here, 76 proteins were identified from watery saliva using transcriptome and proteome analyses. Among them, a putative effector Sg2204 was significantly up‐regulated during feeding stages, transient overexpression in Nicotiana benthamiana...
Aphid salivary proteins are critical in modulating plant defence responses. Grain aphid Sitobion miscanthi is an important wheat pest worldwide. However, the molecular basis for regulation of resistance to cereal aphids remains largely unknown. Here, we show that SmCSP4, a chemosensory protein from S. saliva, secreted into plants during feeding. Delivery SmCSP4 leaves activates salicylic acid (SA)-mediated responses and subsequently reduces performance by deterring feeding behaviour. In...
Odorant-binding proteins (OBPs) and chemosensory (CSPs) of aphids are thought to be responsible for the initial molecular interactions during olfaction that mediate detection chemical signals. Analysis diversity involved comprises critical basic research work will facilitate development sustainable pest control strategies. To help us better understand differences in olfactory system between winged wingless grain aphids, we constructed an antennal transcriptome from Sitobion avenae...
Wheat being staple food of Pakistan is constantly attacked by major wheat aphid species, Schizaphis graminum (R.), Rhopalosiphum padi (L.) and Sitobion avenae (F.). Due to concern on synthetic chemical use in wheat, it imperative search for alternative environment- human- friendly control measures such as botanical pesticides. In the present study, we evaluated comparative role neem seed extract (NSE), moringa leaf (MLE) imidacloprid (I) management well yield losses parameters late planted...
Abstract Background Sitobion miscanthi is an ideal model for studying host plant specificity, parthenogenesis-based phenotypic plasticity, and interactions between insects other species of various trophic levels, such as viruses, bacteria, plants, natural enemies. However, the genome information this has not yet to be sequenced published. Here, we analyzed entire a parthenogenetic female aphid colony using Pacific Biosciences long-read sequencing Hi-C data generate chromosome-length...
Aphid salivary effectors play important roles in modulating plant defense responses. The grain aphid Sitobion miscanthi is one of the most economically cereal aphids worldwide. However, little information available on identification and functional analysis S. miscanthi. In this study, a candidate effector Sm9723 was identified, which specifically expressed glands highly induced during feeding phase. Transient overexpression Nicotiana benthamiana suppressed BAX INF1-induced cell death....
Olfaction is crucial for short distance host location and pheromone detection by insects. Complexes of olfactory receptors (ORs) are composed odor-specific ORs OR co-receptors (Orco). Orcos widely co-expressed with conserved across insect taxa. A number Orco orthologs have been studied to date, although none has identified in cereal aphids. In this study, an gene ortholog was cloned from the grain aphid, Sitobion avenae, named "SaveOrco"; RNA interference (RNAi) reduced expression SaveOrco...
Abstract Multi‐channel amorphous oxide thin‐film transistors (TFTs) with dual gate (DG), coplanar structure are studied. The multi‐channel consists of a top indium gallium zinc tin (a‐IGZTO) and very thin (a‐IZO) bottom layer. fabricated TFTs exhibit high field‐effect mobility (µ FE ) ≈67.1 cm 2 V −1 s , excellent stability under positive bias temperature stress (PBTS). band diagram the TFT is presented based on UV photoelectron spectroscopy, X‐ray UV–vis spectroscopy measurements. PBTS...
In order to develop biological control of aphids by a "push-pull" approach, intercropping using repellent emitting plants was developed in different crop and associated plant models. Garlic is one the potential that could be inserted crops decrease pest occurrence neighboring plots. this study, field works were conducted wheat fields Langfang Experimental Station, Hebei Province China from October 2009 July 2010 during developmental season. The effect with garlic but also volatiles emission...
Aphid saliva plays important roles in aphid-host interactions, such as assisting aphid digestion, detoxification, activating or suppressing plant defenses. The grain aphid, Sitobion avenae, is one of the most devastating pests cereals worldwide. In this study, we performed transcriptome analysis salivary glands S. avenae. A total 33,079 assembled unigenes were identified aphids. Of all obtained unigenes, 15,833(47.86%) and 10,829(32.73%) showed high similarity to known proteins Nr Swiss-Prot...

Abstract BACKGROUND Bacterial symbionts in insects, especially aphids, have a major influence on host adaptation. We previously showed that infection with the secondary symbiont Hamiltonella defensa increases fitness of wheat aphid Sitobion miscanthi , yielding parameters such as adult weight and offspring number. However, whether H. affects sensitivity aphids to insecticides remains unknown. RESULTS tested effects susceptibility chlorpyrifos methyl, imidacloprid, cyantraniliprole...
Infestation with Sitobion avenae induces localized defense responses in wheat; this study, the role of S. watery saliva resistance induction was examined by infiltrating aphid into wheat leaves. After feeding on an artificial diet for 48 h, we first collected from them and then separated salivary proteins using one-dimensional gel electrophoresis. Gene expression studies showed that infiltration leaves induced a strong salicylic acid-responsive but moderate jasmonic acid-dependent defense....
Abstract Using infochemicals to develop a push–pull strategy in pest control is potential way promote sustainable crop production. Infochemicals from plant essential oils were mixed with paraffin oil for slow release field experiments on wheat the population density of cereal aphids and enhance their natural enemies. ( Z )-3-Hexenol (Z3H) attracted Metopolophum dirhodum Sitobion avenae , predominant species Belgium, may be useful infochemical aphid by attracting away plots. Release E...
Bacterial symbionts are omnipresent in insects, particularly aphids, and often exert important effects on the host ecology; however, examples of that mediate herbivore-plant interactions remain limited. Here, three clones with identical genetic backgrounds were established: a Hamiltonella defensa-free clone, H. defensa-infected clone defensa-cured clone. defensa infection was found to increase fitness Sitobion miscanthi by increasing total number offspring decreasing age first reproduction....
Abstract Background Schizaphis graminum is one of the most important and devastating cereal aphids worldwide, its feeding can cause chlorosis necrosis in wheat. However, little information available on wheat defence responses triggered by S. at molecular level. Results Here, we collected analysed transcriptome sequencing data from leaf tissues infested with 2, 6, 12, 24 48 hpi (hours post infestation). A total 44,835 genes were either up- or downregulated differed significantly response to...
Computed tomographic and pathologic correlations of the thymus gland were assessed in 69 patients. The sensitivity computed tomography (CT) for undifferentiated thymic pathology is 87.1%; specificity 85.7%. CT neoplasm or mass 97.1%, 97.1%. lymphoid follicular hyperplasia (LFH) 71.4%, 97.6%. Therefore, a normal-sized on does not exclude LFH. Completely preserved fat planes between adjacent structures usually indicate benign (noninvasive) neoplasm; completely absent malignant (invasive)...
