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

ABSTRACT: 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.

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.

Genome wide gene-expression analysis of the spider mite Tetranychus urticae after long term host transfer from acyanogenic Phaseolus vulgaris cv. 'Prelude' bean plants to cyanogenic Phaseolus lunatus cv. '8078' bean plants

Project description:250 adult T. urticae females from the London strain (grown on acyanogenic P. vulgaris cv. Prelude bean plants) were transferred to cyanogenic P. lunatus cv. 8078 bean plants. Thirty-five generations after the host transfer, total RNA was extracted from mites growing on both bean species (London and London-CYANO strain) and used in in a genome-wide gene expression microarray (Sureprint G3 microarray, Agilent) experiment to assess significantly differentially expressed genes (FC ≥ 2 and FDR-corrected p-value < 0.05) between mites grown on P. vulgaris (cv. Prelude) bean plants (London strain) and mites grown for 35 generations on P. lunatus (cv. 8078) bean plants (London-CYANO strain).

Cyflumetofen resistance in the two-spotted spider mite Tetranychus urticae

Project description:Cyflumetofen is a novel acaricide on the international market with an unknown mode of action. Under laboratory conditions, we selected for high levels of cyflumetofen resistance in a susceptible mite strain and performed genome-wide gene-expression analysis. Differential expression between the resistant and susceptible strain was identified to study on the molecular level how mites develop resistance to this novel acaricide. Our results show that in T. urticae, the selection for cyflumetofen resistance resulted in a differential expression in only a limited number of genes. This transcriptomic study provides an unbiased look how cyflumetofen resistance triggers selection on the transcriptional level in T. urticae. 4 replicates for one comparison; per replicate 150 mites were pooled. Mites of the derived cyflumetofen resistant spider mite (cy5-labelled) were directly compared to mites of the ancestral susceptible strain (cy3-labelled).

Tetranychus urticae secretome - The Salivary Protein Repertoire of the Polyphagous Spider Mite Tetranychus urticae: A Quest for Effectors

Project description:The two-spotted spider mite Tetranychus urticae is an extreme polyphaguous crop pest. Next to an increased detoxification potential of plant secondary metabolites, it has recently been shown that spider mites manipulate plant defences. Salivary constituents are proposed to play an important role during the interaction with its many hosts. The proteomic composition of saliva delivered into artificial diet by spider mites adapted to various hosts - bean, soy, maize, tomato -was determined using Orbitrap mass spectrometry. Over 200 different proteins were identified, many of unknown function and in numerous cases belonging to multi-membered gene families. A selection of these putative salivary proteins was validated using whole-mount in situ hybridizations and expression was shown to be localized in the anterior and dorsal podocephalic glands of the spider mite. Host-plant dependent expression was evident from the proteomics dataset and was further studied in detail by micro-array based genome wide gene expression profiling of mites maintained on the host plants under study. Previously obtained gene-expression datasets were further used to get more insight in the expression profile over different life stages and physiological states. To conclude, for the first time the T. urticae salivary proteome repertoire was characterized using a custom feeding hemisphere-based enrichment technique. This knowledge will assist in unraveling the molecular interactions between phytophagous mites and their host plants. This may ultimately facilitate the development of mite-resistant crops.

Genome wide gene-expression analysis of facultative reproductive diapause in the two-spotted spider mite Tetranychus urticae

Project description:Investigating essential physiological processes in diapausing mites by analyzing genome wide gene expression changes using custom-built microarray. We investigated the molecular biology of facultative reproductive diapause in the chelicerate Tetranychus urticae (Acari: Tetranychidae) by analyzing genome-wide gene expression differences in diapausing and non diapausing T. urticae, using an Agilent custom-built two color gene expression microarray. Analysis of this dataset showed that a remarkable number, 11% of the total number of predicted T. urticae genes, were differentially expressed. Gene Ontology analysis revealed that many metabolic pathways were affected in diapausing females. Genes related to digestion and detoxification, cryo-protection, carotenoid synthesis and the organization of the cytoskeleton were profoundly influenced by the state of diapause. We also further confirmed the importance of horizontally transferred carotenoid synthesis genes in diapause and different color morphs of T. urticae. We made one comparison: diapausing mites (DIA) vs non-diapausing mites (NON-DIA), in 4 replicates. Both types of mites belonged to the T. urticae LS-VL strain. In this strain, approximately 30% of mites enter diapause under the experimental conditions applied. Hence, we were able to sample RNA of mites with similar genetic background that were reared under identical environmental conditions. The labeled cRNA samples were pooled and hybdrized to a custom Sureprint genome wide G3 Gene Expression 8x60K microarray. Data was normalized by Agilent Feature Extraction software (using protocol GE2_107_SEP09). Genespring software (Agilent technologies) was used for the statistical analysis of the data.

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).
