Project description:The two-spotted spider mite, Tetranychus urticae, is one of the most significant mite pests in agriculture that can feed on more than 1,100 plant hosts, including model plants Arabidopsis thaliana and tomato, Solanum lycopersicum. In order to refine the involvement of jasmonic acid (JA) in mite-induced responses, we analyzed transcriptional changes in tomato JA signaling mutant defenseless1 (def-1) upon JA treatment and spider mite herbivory. We used microarray to assess global gene expression in Solanum lycopersicum def-1 cv. Castlemart upon jasmonic acid treatment and Tetranychus urticae attack. 1 month old def-1 tomato plants were subjected to Tetranychus urticae attack through application of 100 adult mites on a terminal leaflet of leaf 3 for 24 h or plants were sprayed with 1 mM jasmonic acid solution.

Project description:Generalist arthropod herbivores rapidly adapt to a broad range of host plants. However, the extent of transcriptional reprogramming in the herbivore and its hosts associated with adaptation remains poorly understood. Using the spider mite Tetranychus urticae and tomato as models with available genomic resources, we investigated the reciprocal genome-wide transcriptional changes in both spider mite and tomato as a consequence of mite’s adaptation to tomato We used microarray to assess global gene expression in Solanum lycopersicum cv. Moneymaker upon Tetranychus urticae attack by tomato-adapted and non-adapted spider mite lines.

Project description:While pathogen-induced immunity is comparatively well characterized, far less is known about plant defense responses to arthropod herbivores. To date, most molecular-genetic studies of plant-arthropod interactions have focused on insects. However, plant-feeding (phytophagous) mites are also pests of diverse plants, and mites induce different patterns of damage to plant tissues than do well-studied insects (e.g., Lepidopteran larvae or aphids). The two-spotted spider mite, Tetranychus urticae, is among the most significant mite pests in agriculture. T. urticae is an extreme generalist that has been documented on a staggering number of plant hosts (more than 1,100), and is renowned for the rapid evolution of pesticide resistance. To understand reciprocal interactions between T. urticae and a plant host at the molecular level, we examined mite herbivory using Arabidopsis thaliana. Despite differences in feeding guilds, we found that transcriptional responses of A. thaliana to mite herbivory generally resembled those observed for insect herbivores. In particular, defense to mites was mediated by jasmonic acid (JA) biosynthesis and signaling. Further, indole glucosinolates dramatically increased mite mortality and development times. Variation in both basal and activated levels of these defense pathways might also explain differences in mite damage and feeding success between A. thaliana accessions. On the herbivore side, a diverse set of genes associated with detoxification of xenobiotics was induced upon exposure to increasing levels of in planta indole glucosinolates. Our findings provide molecular insights into the nature of, and response to, herbivory for a representative of a major class of arthropod herbivores. We used microarray to assess global gene expresion in Arabidopsis thaliana upon Tetranychus urticae attack in two A. thaliana accessions: Bla-2, resistant to spider mite herbivory and Kon, susceptible to spider mite herbivory. 3 week old Arabidopsis thaliana plants were subjected to Tetranychus urticae attack through application of 10 mites for various periods of time (timecourse scenario) or hundreds of mites for 1 hour (feeding site scenario).

Project description:The red spider mite, Tetranychus evansi, is a oligophagous specialist mite pest of Solanaceae plants. Here, we described tomato transcriptional responses to T. evansi feeding and compared them to responses to tomato-adapted and -non-adapted strains of generalist herbivorous spider mite Tetranychus urticae. We used microarray to assess global gene expression in Solanum lycopersicum cv. Heinz 1706 upon T. evansi attack.

Project description:The two-spotted spider mite, Tetranychus urticae, is one of the most significant mite pests in agriculture that can feed on more than 1,100 plant hosts, including model plants Arabidopsis thaliana and tomato, Solanum lycopersicum. Here, we described tomato transcriptional responses to spider mite feeding and compared them to Arabidopsis in order to determine conserved and divergent responses to this pest. 2,133 differentially expressed genes (DEGs) were detected at 1, 3, 6, 12 or 24 hours post spider mite infestation (hpi) relative to non-infested control plants. Based on Biological Process Gene Ontology annotations, improved in the course of our analysis, DEGs were grouped in 60 significantly enriched gene sets that highlighted perception of the spider mite attack (1 hpi), metabolic reprogramming (3-6 hpi), and establishment and maintenance of the defense responses (6-24 hpi). We used microarray to assess global gene expression in Solanum lycopersicum cv. Heinz 1706 upon Tetranychus urticae attack. 1 month old tomato plants were subjected to Tetranychus urticae attack through application of 100 adult mites on a terminal leaflet of leaf 3 for various periods of time (timecourse scenario) or hundreds of mites for 1 hour (feeding site scenario).
