Abstract A parasitoid’s decision to reject or accept a potential host is fundamental its fitness. Superparasitism, in which more than one egg of given parasitoid species can deposit single host, usually considered sub-optimal systems where the able support development only parasitoid. It follows that selection pressure may drive capacity for parasitoids recognize parasitized hosts, especially if there fitness cost superparasitism. Here, we used microsatellite studies two distinct populations...
Minsheng You and colleagues report the whole-genome sequence of diamondback moth, Plutella xylostella. Their transcriptome analysis from different life stages, together with comparative genomic phylogenetic analysis, provides insights into herbivore evolution insect adaptation to plant feeding detoxification. How an evolves become a successful is profound biological practical importance. Herbivores are often adapted feed on specific group evolutionarily biochemically related host plants1,...
Abstract Tea is an important global beverage crop and largely clonally propagated. Despite previous studies on the species, its genetic evolutionary history deserves further research. Here, we present a haplotype-resolved assembly of Oolong tea cultivar, Tieguanyin. Analysis allele-specific expression suggests potential mechanism in response to mutation load during long-term clonal propagation. Population genomic analysis using 190 Camellia accessions uncovered independent histories parallel...
The development of insecticide resistance in insect pests is a worldwide concern and elucidating the underlying mechanisms critical for effective crop protection. Recent studies have indicated potential links between gut microbiota these may apply to Diamondback moth, Plutella xylostella (L.), globally economically important pest cruciferous crops. We isolated Enterococcus sp. (Firmicutes), Enterobacter (Proteobacteria), Serratia (Proteobacteria) from guts P. analyzed effects on, resistance....
Background Insect midgut microbiota is important in host nutrition, development and immune response. Recent studies indicate possible links between insect gut resistance to biological chemical toxins. Studies of this phenomenon symbionts general have been hampered by difficulties culture-based approach. In the present study, DNA sequencing was used examine diamondback moth (DBM), Plutella xylostella (L.), a destructive pest that attacks cruciferous crops worldwide. Its ability develop many...
Herbivore specialists adapt to feed on a specific group of host plants by evolving various mechanisms respond plant defences. Insects also possess complex gut microbiotas but their potential role in adaptation is poorly understood. Our previous study the genome diamondback moth, Plutella xylostella, revealed an intrinsic capacity detoxify defence compounds, which important factor its success as pest. Here we expand that work with complete taxonomic and functional profile P. xylostella...
Silicon (Si) is important in plant defenses that operate a direct manner against herbivores, and work rice (Oryza sativa) has established this mediated by the jasmonate signaling pathway. Plant also indirectly, production of herbivore induced volatiles (HIPVs) attract predators parasitoids herbivores. These indirect too are pathway but no earlier demonstrated an effect Si on HIPVs. In study, we tested supplementation versus deprivation to plants subsequent HIPV following feeding pest,...
Abstract Cytochrome P450 monooxygenases are present in almost all organisms and can play vital roles hormone regulation, metabolism of xenobiotics biosynthesis or inactivation endogenous compounds. In the study, a genome-wide approach was used to identify analyze gene family diamondback moth, Plutella xylostella , destructive worldwide pest cruciferous crops. We identified 85 putative cytochrome genes from P. genome, including 84 functional 1 pseudogene. These were classified into 26...
In many organisms, cytochrome P450 enzymes are the primary detoxifying enzymes. Enhanced activity can be mediated by emergence of new genes, increased transcription due to mutations in promoter regions, changes enzyme structures and functions protein-coding or post-translational modifications; all these subject insecticide selection pressure. Multiple signalling pathways key effector molecules involved regulation insect P450s. Increased is a mechanism inducing resistance. Hence,...
Brassica vegetable and oilseed crops are attacked by several different flea beetle species (Chrysomelidae: Alticini). Over the past decades, most research has focused on two Phyllotreta species, striolata cruciferae, which major pests of rape in North America. More recently, especially after ban neonicotinoids European Union, cabbage stem beetle, Psylliodes chrysocephala, become greatly important is now considered to be pest winter Europe. The challenges control prediction population...
Glutathione S-transferases (GSTs) are multifunctional detoxification enzymes that play important roles in insects. The completion of several insect genome projects has enabled the identification and characterization GST genes over recent years. This study presents a genome-wide investigation diamondback moth (DBM), Plutella xylostella, species which GSTs special importance because this pest is highly resistant to many insecticides.A total 22 putative cytosolic were identified from published...
The diamondback moth Genome Database (DBM-DB) is a central online repository for storing and integrating genomic data of (DBM), Plutella xylostella (L.). It provides comprehensive search tools downloadable datasets scientists to study comparative genomics, biological interpretation gene annotation this insect pest. DBM-DB contains assembled transcriptome from multiple DBM strains developmental stages, the annotated genome P. (version 2). We have also integrated publically available ESTs NCBI...
The diamondback moth, Plutella xylostella, is a cosmopolitan pest and the first species to develop field resistance toxins from gram-positive bacterium Bacillus thuringiensis (Bt). Although previous work has suggested that mutations of ATP-binding cassette transporter subfamily C2 (ABCC2) or C3 (ABCC3) genes can confer Cry1Ac resistance, here we reveal P. xylostella requires combined in both PxABCC2 PxABCC3 achieve high-level rather than simply mutation either gene. We identified natural...
Insect gut microbes play important roles in host feeding, digestion, immunity, growth and development.
The diamondback moth, Plutella xylostella is a cosmopolitan pest that has evolved resistance to all classes of insecticide, and costs the world economy an estimated US $4-5 billion annually. We analyse patterns variation among 532 P. genomes, representing worldwide sample 114 populations. find evidence suggests South America geographical area origin this species, challenging earlier hypotheses Old-World origin. Our analysis indicates experienced three major expansions across world, mainly...
Abstract Understanding the genetic basis of climatic adaptation is essential for predicting species’ responses to climate change. However, intraspecific variation these arising from local remains ambiguous most species. Here, we analyze genomic data diamondback moth ( Plutella xylostella ) collected 75 sites spanning six continents reveal that climate-associated adaptive exhibits a roughly latitudinal pattern. By developing an eco-genetic index combines and physiological responses, predict...
