Spider mite preliminary feeding experiment with mites reared on bean and two Arabidopsis thaliana accessions

Project description:We sequenced messenger RNA from mixed stages of the two-spotted spider mite (Tetranychus urticae) reared on bean (Phaseolus vulgaris cv California Red Kidney; the laboratory host plant for mites) and two Arabidopsis thaliana accessions which were considered to either be susceptible (Kondara) or resistant (Bla-2) to mite feeding. This pilot experiment was conducted to assess gene expression differences of mites grown on sensitive versus resistant Arabidopsis accessions, as well as differences in mites feeding on different host species. The expression data was used for gene model validation of genes predicted by EuGene in the spider mite genome and to assess gene expression levels. Examination of gene expression of spider mites reared on beans and two Arabidopsis accessions (Kondara and Bla-2).

Developmental stage-specific gene expression in the two-spotted spider mite (Tetranychus urticae)

Project description:We generated 77-bp Illumina reads from single messenger RNA libraries from four diverse developmental stages of the two-spotted spider mite to maximally capture the complement of transcribed sequences across development. Adult, nymphal, larvae and embryonic stages were separated using sieves of various pore sizes, and mites of various developmental stages were carefully selected for transcriptome library preparation. Samples were a mix of males and females to capture male and female patterns of transcription, and were reared on beans (Phaseolus vulgaris cv California Red Kidney). The RNA-Seq data was used for validation of gene models predicted by EuGene, and to study patterns of gene expression across development. Gene expression for spider mites from adult, nymph, larvae and embryonic developmental stages was examined (technical replicates were generated).

Developmental stage-specific small RNA composition in the two-spotted spider mite (Tetranychus urticae)

Project description:We generated 38-bp Illumina reads from single messenger RNA libraries from three diverse developmental stages of the two-spotted spider mite to capture small RNA diversity across development. Adult, nymphal+larvae and embryonic stages were separated using sieves of various pore sizes, and mites of various developmental stages were carefully selected for small RNA library preparation. Samples were a mix of males and females to capture male and female patterns of small RNA composition and were reared on beans (Phaseolus vulgaris cv California Red Kidney). Small RNA reads were used for miRNA prediction, piRNA discovery, and for quantitation of small RNA-generating loci (i.e. expression across development). Examination of small RNA from spider mites of adult, embryonic and pooled larval/nymphal developmental stages.

Transcriptional responses of the two-spotted spider mite (Tetranychus urticae) after transfer to different plant hosts

Project description:We generated 38-bp Illumina reads from messenger RNA libraries from mites transferred from their preferred laboratory host, bean (Phaseolus vulgaris cv. California Red Kidney), to one of three hosts: bean, Arabidopsis thaliana (Bla-2 accession) and the tomato (Solanum lycopersicum; genotype Heinz 1706). Larvae were carefully collected from bean plants and transferred to the treatment plant. Mites were reared on these plants for ~24 hours, after which mites were collected for mRNA library preparation. Samples were a mix of males and females. The goal of the study was to identify genes that may underlie the ability of mites to be herbivores on different host plants. Mites were transferred from host bean plants to two non-preferred hosts (Arabidopsis thaliana and tomato). RNA was then collected, and RNA-seq was performed on the Illumina platform. For each of three host plants, three biological replicates were generated.

Host plant shift and acaricide resistance effects on gene expression in the two-spotted spider mite, T. urticae

Project description:The goal of our microarray experiments was twofold: 1) Compare the gene expression profile of acaricide resistant spider mite strains (MAR-AB and MR-VP) with that of a susceptible spider mite strain (London); 2) Study gene expression changes in spider mites from the London strain upon transfer from bean, a suitable host, to tomato, a less favorable host. These gene expression changes upon host change were measured for three timepoints (2 hour on tomato (Tomato-2h), 12 hour on tomato (Tomato-12h) and 5 generations on tomato (Tomato-5G)). 23 samples were analyzed: 6 biological replicates for MR-VP, 5 biological replicates for MAR-AB and four biological replicates each for Tomato-2h, Tomato-12h and Tomato-5G

RNA-Seq of Wolbachia infected and uninfected spider mites

Project description:Four spider mites strains, 1-3 day old adult females with and without Wolbachia infection (Turt_FI, Turt_Fu),and 1 day old adult males with and without Wolbachia infection (Turt_MI, Turt_MU).The four samples were sequenced on the Illumina HiSeq2000 platform.

RNA-seq of barley lines after dehydration, spider mite or combined stress.

Project description:Drought and herbivores are main threats to crop production. Barley plants were subjected to dehydration, spider mite attack or to a combination of both stresses. RNA-seq analyses were done to know how individual and double abiotic-biotic stresses promote changes in the transcriptome.

Time course RNA-seq data from barley infested with Tetranychus urticae and Banks grass mite

Project description:Spider mites, including the two-spotted spider mite (Tetranychus urticae, TSSM) and the Banks grass mite (Oligonychus pratensis, BGM), are becoming increasingly important agricultural pests. The TSSM is an extreme generalist documented to feed on more than 1100 plant hosts. In contrast, the BGM is a grass specialist, with hosts including important cereal crops like maize, wheat, sorghum and barley. Historically, studies of plant-herbivore interactions have focused largely on insects. However, far less is known about plant responses to spider mite herbivores, especially in grasses, and whether responses differ between generalists and specialists. To identify plant defense pathways responding to spider mites, we collected time course RNA-seq data from barley (Hordeum vulgare L.) infested with TSSMs and BGMs. Additionally, and as a comparison to the physical damage caused by spider mite feeding, a wounding treatment was also included. The experiment was performed with four biological replicates across each of the following (28 samples in total): no infestation (C, control), 2hr after wounding (W2), 24hr after wounding (W24), 2hr after TSSM infestation (T2), 24hr after TSSM infestation (T24), 2hr after BGM infestation (B2), and 24hr after BGM infestation (B24).
