Identification and expression profiling of Helicoverpa armigera microRNAs and their possible role in the regulation of digestive protease genes

Project description:Using Illumina platform, deep sequencing of 12 small RNA libraries was performed from Helicoverpa armigera larvae fed on artificial diet (AD) or recombinant Capsicum annuum PI-7 (rCanPI-7) incorporated diet at various time intervals (0.5, 2, 6, 12, 24, and 48h). Several candidate miRNAs (conserved and novel) were differentially expressed in rCanPI-7 fed larvae as compared to the larvae fed on AD. The investigation revealed potential roles of miRNAs in H. armigera protease gene regulation.

Histone deacetylase 3: A potential target fight against Helicoverpa armigera

Project description:Insect development requires genes to be expressed in strict spatiotemporal order. The degree of histone acetylation regulates insect development, via histone acetyltransferases (HATs) and histone deacetylases (HDACs). Although HDAC3 is required for early embryonic development, its functions in Helicoverpa armigera remain unclear. We treated H. armigera with HDAC3 siRNA and RGFP966, a specific inhibitor, examining how HDAC3 loss-of-function affects growth and development. HDAC3 siRNA and RGFP966 treatment increased mortality at each growth-stage and altered metamorphosis, hampering pupation and causing abnormal wing development, reduced egg production, and reduced hatching rate. RNA-seq analysis identified 2,788 differentially expressed genes (≥ two-fold change; P ≤ 0.05) between siHDAC3- and siNC-treated larvae. Kr-h1, were differentially expressed in HDAC3 knockdown larvae. Pathway enrichment analysis revealed significant enrichment of genes involved in the Hippo, MAPK, and Wnt signaling pathways following HDAC3 knockdown. Histone H3K9 acetylation was increased in H. armigera after siHDAC3 treatment. In conclusion, HDAC3-knockdown dysregulated 20-hydroxyecdysone hormone-related and apoptosis-related genes in H. armigera, affecting many basic processes, including cell cycle regulation, metabolism, and signal transduction. The Result showed that HDAC3 gene can serve as a potential target for fighting against Helicoverpa armigera.

Helicoverpa armigera gene expression on gossypol suppelemented diet, larval gut and rest of body

Project description:The transcriptional response of H. armigera larvae was analyzed after feeding on gossypol supplemented diet, a toxic secondary metabolite produced in cotton plants, to detect potential detoxification enzymes possibly involved in detoxification of gossypol by H. armigera. A one-color microarray-based gene expression analysis was performed with Cy3 labeled cRNA of gut and rest of the body of H. armigera larvae that fed on 0.016%, 0.16% gossypol and control diet. For each treatment and tissue four biological replicates were used.

Integrated transcriptomic and proteomic analyses revealed the participation of endogenous protease inhibitors in the regulation of protease gene expression in Helicoverpa armigera

Project description:Insects adapt to plant protease inhibitors (PIs) present in their diet by differentially regulating multiple digestive proteases. However, mechanisms regulating protease gene expression in insects are largely enigmatic. Ingestion of Capsicum annuum protease inhibitor-7 (CanPI-7) arrests growth and development of Helicoverpa armigera (Lepidoptera: noctuidae). Using de novo RNA sequencing and proteomic analysis, we examined the response of H. armigera larvae fed on recombinant C. annuum PI (CanPI) at different time intervals. Here, we present evidence supporting a dynamic transition in H. armigera protease expression upon CanPI feeding with general down-regulation of protease genes at early time points (0.5 to 6 h) and significant up-regulation of specific trypsin, chymotrypsin and aminopeptidase genes at later time points (12 to 48 h).

Dynamic transcriptome analysis and volatile profiling of Gossypium hirsutum in response to the cotton bollworm Helicoverpa armigera

Project description:Cotton seeds (Gossypium hirsutum cv. CCRI12) were grown in a growth chamber under 29/25°C temperature and a 16:8 h light:dark cycle, and water was added every two days. All plants were used in experiments at the 6-7 fully expanded true leaf stage, which occurred 5-6 weeks after sowing. Cotton bollworm (CBW; Helicoverpa armigera) larvae were reared on an artificial diet and maintained at 27 ± 2°C, 75 ± 10% relative humidity, and 14:10 h light:dark in the laboratory. For insect treatment, seven H. armigera larvae (third instars) were placed on a group of three plants, which were kept within plastic bags (30 × 40 cm), until time of harvest, with samples for each time point maintained separately. Undamaged plants maintained under the same conditions were used as controls. Cotton leaves from control plants and plants exposed to H. armigera were harvested at 6 h, 12 h, 24 h, and 48 h after onset of herbivory. For each treatment group and time point, cotton leaves were harvested from the three plants per treatment group and flash frozen in liquid nitrogen. For each time point, three replicate treatments and controls were performed.

Transcriptional responses underlying the hormetic and detrimental effects of gossypol on Helicoverpa armigera

Project description:Gut and rest of body tissue from fifth instar larvae which fed for three days a diet containing different doses of gossypol. Transcriptional profiling comparing gut and rest of body samples for three gossypol concentrations (0%, 0.016%-hormetic dose & 0.16%-detrimental dose). Hormesis is a biphasic biological response characterized by the stimulatory effect at relatively low amounts of chemical compounds otherwise known to be detrimental at higher concentrations. A hormetic response in larval growth rates has been observed in cotton-feeding insects in response to increasing concentrations of gossypol, a toxic metabolite found in the pigment glands of some Malvaceae plants. We investigated the developmental effect of gossypol in the cotton bollworm, Helicoverpa armigera, an important heliothine pest species, by exposing larvae to different doses of this metabolite in their diet. In addition, we sought to determine the underlying transcriptional responses to different gossypol doses. Larval weight gain, pupal weight and larval development time were measured in feeding experiments and a hormetic response was seen for the first two characters. On the basis of net larval weight gain responses to gossypol, three treatments, that is 0%, 0.016% and 0.16% gossypol , were selected for transcript profiling in the gut and the rest of the body in a two-color double reference design microarray experiment.
