The spider mite Tetranychus urticae is a cosmopolitan agricultural pest with an extensive host plant range and extreme record of pesticide resistance. Here we present the completely sequenced annotated genome, representing first complete chelicerate genome. At 90 megabases T. has smallest arthropod Compared other arthropods, genome shows unique changes in hormonal environment organization Hox complex, also reveals evolutionary innovation silk production. We find strong signatures polyphagy...
Plants produce a wide range of allelochemicals to defend against herbivore attack, and generalist herbivores have evolved mechanisms avoid, sequester, or detoxify broad spectrum natural defense compounds. Successful arthropod pests also developed resistance diverse classes pesticides this adaptation is critical importance agriculture. To test whether overcome plant defenses predispose the development pesticide resistance, we examined two-spotted spider mite, Tetranychus urticae , host...
Because of its importance to the arthropod exoskeleton, chitin biogenesis is an attractive target for pest control. This point demonstrated by economically important benzoylurea compounds that are in wide use as highly specific agents control insect populations. Nevertheless, sites inhibit have remained elusive, likely preventing full exploitation underlying mode action management. Here, we show acaricide etoxazole inhibits Tetranychus urticae (the two-spotted spider mite), pest. We then...
The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is one of the most polyphagous herbivores feeding on cell contents over 1100 plant species including more than 150 crops. It being established as a model for chelicerate with tools that enable tracking reciprocal responses in plant-spider mite interactions. However, despite their important pest status and growing understanding molecular basis interactions hosts, knowledge way mites interface while damage directly...
Cyanogenic glucosides are among the most widespread defense chemicals of plants. Upon plant tissue disruption, these hydrolyzed to a reactive hydroxynitrile that releases toxic hydrogen cyanide (HCN). Yet many mite and lepidopteran species can thrive on plants defended by cyanogenic glucosides. The nature enzyme known detoxify HCN β-cyanoalanine in arthropods has remained enigmatic. Here we identify this transcriptome analysis functional expression. Phylogenetic showed gene is member...
The ABC (ATP-binding cassette) gene superfamily is widespread across all living species. majority of genes encode transporters, which are membrane-spanning proteins capable transferring substrates biological membranes by hydrolyzing ATP. Although transporters have often been associated with resistance to drugs and toxic compounds, within the Arthropoda families only characterized in detail several insects a crustacean. In this study, we report genome-wide survey expression analysis spider...
Carotenoids underlie many of the vibrant yellow, orange, and red colors in animals, are involved processes ranging from vision to protection stresses. Most animals acquire carotenoids their diets because de novo synthesis is primarily limited plants some bacteria fungi. Recently, sequencing projects aphids adelgids, spider mites, gall midges identified genes with homology fungal sequences encoding carotenoid biosynthetic proteins like phytoene desaturase. The finding horizontal gene...
RNA interference (RNAi) can be used for the protection against agricultural pests through silencing of genes required pest fitness. To assess potential RNAi approaches in two-spotted spider mite, Tetranychus urticae, we compared 5 methods delivery double-stranded (dsRNA). These include mite feeding on either (i) leaves floating a dsRNA solution, (ii) dsRNA-expressing plants, (iii) artificial diet supplemented with dsRNA, or (iv) dsRNA-coated leaves, and (v) soaking solution. In all cases,...
The two-spotted spider mite Tetranychus urticae is one of the most significant pests in agriculture, feeding on more than 1,100 plant hosts, including model plants Arabidopsis thaliana and tomato, Solanum lycopersicum. Here, we describe timecourse tomato transcriptional responses to compare them with order determine conserved divergent defense this pest. To refine involvement jasmonic acid (JA) mite-induced improve Gene Ontology annotations, analyzed changes JA-signaling mutant defenseless1...
The ancestral arthropod is believed to have had a clustered arrangement of ten Hox genes. Within arthropods, gene mutations result in transformation segment identities. Despite the fact that variation number/character was common diversification few examples gains/losses been correlated with morphological evolution. Furthermore, full appreciation genomic genes extant arthropods has not recognized, as genome sequences from each major clade reported until recently. Initial analysis chelicerate...
Abstract Global viticulture has evolved following market trends, causing loss of cultivar diversity and traditional practices. In Montenegro, modern co-exists with a that still maintains ancient practices exploits local cultivars. As result, this region provides unique opportunity to explore processes increasing genetic diversity. To evaluate the Montenegrin grapevines involved in their diversification, we collected analyzed 419 samples situ across country (cultivated plants from old...

Embryo segmentation has been studied extensively in the fruit fly,Drosophila. These studies have demonstrated that a mechanism acting with dual segment periodicity is required for correct patterning of body plan this insect, but evolutionary origin mechanism, pair-rule system, unclear. We examined expression homologues two Drosophila genes, runt andpaired (Pax Group III), segmenting embryos two-spotted spider mite (Tetranychus urticae Koch). Spider mites are chelicerates, group arthropods...
The complete genome of the two-spotted spider mite, Tetranychus urticae, has been reported. This is first sequenced a highly polyphagous and resistant agricultural pest. question as to what offers community working on mite control addressed.
The two-spotted spider mite, Tetranychus urticae, is a ubiquitous polyphagous arthropod herbivore that feeds on remarkably broad array of species, with more than 150 economic value. It major pest greenhouse crops, especially in Solanaceae and Cucurbitaceae (e.g., tomatoes, eggplants, peppers, cucumbers, zucchini) ornamentals roses, chrysanthemum, carnations), annual field crops (such as maize, cotton, soybean, sugar beet), perennial cultures (alfalfa, strawberries, grapes, citruses,...

Abstract Comprehensive understanding of pleiotropic roles RNAi machinery highlighted the conserved chromosomal functions RNA interference. The consequences evolutionary variation in core pathway genes are mostly unknown, but may lead to species-specific associated with gene silencing. two-spotted spider mite, Tetranychus urticae, is a major polyphagous chelicerate pest capable feeding on over 1100 plant species and developing resistance pesticides used for its control. A well annotated...
When a parasitoid is searching for hosts, not all hosts are equally likely to be attacked. This variability in attack probability may affect the functional response. Using collection of experiments, we quantified response Aphidius ervi (Hymenoptera: Braconidae), an insect pea aphid Acyrthosiphon pisum (Homoptera: Aphididae). We measured number attacked by foraging both among plants and within plants. At first scale, A. ervi, containing different numbers aphids, showed aphid-density-dependent...
