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, and sorghum. Historically, studies of plant-herbivore interactions have focused largely on insects. As such, far less is known about plant responses to spider mite herbivores, especially in grasses, and whether responses differ between generalist and specialist mites. To identify plant defense pathways responding to spider mites, we collected time course RNA-seq data from maize (Zea mays) 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. In total, four biological samples were generated per treatment.

Project description:Spider silk proteins are synthesized in the silk-producing glands, where the spidroins are produced, stored and processed into a solid fiber from a crystalline liquid solution. Despite great interest in the spider silk properties, that make this material suitable for biomedical and biotechnological applications, the mechanism of formation and spinning of the silk fibers has not been fully elucidated; and no combination of proteomic and transcriptomic study has been carried out so far in the spider silk-producing glands. Nephila clavipes is an attractive orb-web spider to investigate the spinning process of silk production, given the properties of strength, elasticity and biocompatibility of their silk fibers. Thus, considering that the combination of proteomic and transcriptomic analysis may reveal an extensive repertoire of novel proteins involved in the silk spinning process, and in order to facilitate and enable proteomics in this non-model organism, the current study aims to construct a high quality reference mRNA-derived protein database that could be used to identify tissue specific expression patterns in spider silk glands. Next-generation sequencing has offered a powerful and cost-efficient technique for the generation of transcriptomic datasets in non-model species using diverse platforms such as the Illumina HiSeq, Roche 454, Pacific Biosystems, and Applied Biosystems SOLiD; In the current study, the Illumina HiSeq 2000 platform will be used to generate a N. clavipes spider silk glands transcriptome-based protein database. The transcriptome data generated in this study will provide a comprehensive and valuable genomic resource for future research of the group of spider silk-producing glands, in order to improve our understanding of the overall mechanism of action involved in production, secretion, storage, transport, protection and conformational changes of spidroins during the spinning process, and prey capture; and the results may be relevant for scientists in material Science, biology, biochemistry, and environmental scientists.

Project description:Transcriptional profiling of Candida albicans comparing SDH2 deletion mutant cells with the wild-type cells in both Spider medium and Spider medium supplemented with 100mM glucose The SDH2 deletion mutant sdh2Î/Î and the wild-type strain SC5314 were used to perform the microarray experiments. Two-condition experiments: sdh2Î/Î vs SC5314 in Spider midium and sdh2Î/Î vs SC5314 in Spider midium supplemented with 100mM glucose. Biological replicates: 3 SDH2 deletion mutant sdh2Î/Î samples (test group), 3 wild-type strain SC5314 samples (control group), independently grown and harvested. One replicate per array.

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:The common house spider Parasteatoda tepidariorum is a chelicerate model organism for studying developmental mechanisms and their evolution in arthropods. In contrast to the well-studied model insect, Drosophila melanogaster, embryos of the spider undergo patterning in a cellular environment from early stages (at least after the number of the nuclei increase to 16). Use of spider embryos provide new opportunities to understand the evolution of developmental mechanisms underlying arthropod body plans. This analysis aims to generate genome-scale, developmental profiles of gene expression in embryos of the spider P. tepidariorum, which facilitate a wide range of studies using this spider species.

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).
