Project description:The goal of our microarray experiments was to compare the gene expression profile of two spirodiclofen resistant spider mite strains (SR-VP and SR-TK) with that of a susceptible spider mite strain (LS-VL) 5 samples were analyzed: 3 biological replicates for SR-VP, 2 biological replicates for SR-TK

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.

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)).

Project description:Cyenopyrafen is a novel acaricide with a currently unknown mode of action. We selected for high levels of cyenopyrafen resistance in a susceptible spider mite strain and previously published patterns of cross-resistance to other well-described acaricides (Khalighi et al., 2014). In addition, we also included an independent cyenopyrafen-susceptible mite strain (referred to as Akita) in this study. We performed transcriptomic analysis to identify on the molecular level how T. urticae develops resistance to this novel acaricide. Using this dataset, we show that the selection for cyenopyrafen resistance resulted in massive transcriptomic responses in T. urticae. The multi-gene family of cytochrome P450 monooxygenases (CYPs) exhibited a drastic differential expression with a significant transcriptional induction in the acaricide resistant strain. This transcriptomic study highlights the potential importance of CYPs in mite resistance to the cyenopyrafen acaricide.

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.

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).

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.
