(Submitter supplied) 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. more...

(Submitter supplied) 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. more...

(Submitter supplied) 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. more...

(Submitter supplied) 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). more...

(Submitter supplied) Tomato plants are commonly attacked by herbivorous mites, including by generalist Tetranychus urticae and specialists Tetranychus evansi and Aculops lycopersici. Mite feeding induces plant defense responses that reduce mite performance. However, via poorly understood mechanisms, T. evansi and A. lycopersici suppress plant defenses and, consequently, maintain a high performance on tomato. Accordingly, on a shared host, non-adapted T. more...

(Submitter supplied) 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)).

(Submitter supplied) Loliolide, a metabolite of carotenoid metabolic pathways in plants, was identified as an inducer of resistance to herbivores such as the two-spotted spider mite, Tetranychus urticae, and the common cutworm, Spodoptera litura. To identify host factors involved in loliolide-induced herbivore resistance, microarray analysis of tomato plants treated with loliolide was performed. We identified several cell wall-associated defense genes as loliolide-responsive genes.

(Submitter supplied) In an experimental evolutionary set-up, we transferred a genetically diverse strain of the spider mite Tetranychus urticae from its common host bean to tomato where replicated populations were allowed to adapt. By sampling the transcriptomes of non-adapted and adaptes mites feeding on bean and tomato, we identified gene-expression changes in the spider mite affiliated with tomato adaptation. Transcriptional analysis revealed that both constitutive gene-expression levels as well as the transcriptional plasticity of genes were affected. more...

(Submitter supplied) Proteins produced in the salivary glands of arthropod herbivores can function as effectors to modify plant defense responses. To obtain a set of candidate, salivary gland specific genes for the mite herbivore Tetranychus urticae, mites were dissected and the head region was recovered. Specifically, the proterosoma was dissected from 250 mites. This includes the salivary glands, and other nearby tissue (given their small size, exact micro-dissection of salivary glands was not possible). more...

(Submitter supplied) A genetically diverse strain (labelled as London) of the phytophagous mite Tetranychus urticae was transferred from its common host (bean) to other host plants (cotton, maize or soy). Three different host plant species were included in the experimental set-up: cotton (Gossypium spp.), maize (Zea mays cv. Ronaldinio) and soy (Glycine max cv. Merlin). Five generations after host-transfer, total RNA of all mite populations (London, London-SOY, London-MAIZE and London-COTTON) was collected and used in a genome-wide gene expression microarray (Sureprint G3 microarray, Agilent) Microarray analysis revealed large-scale differential expression of genes coding for enzymes of detoxification families, secreted proteins with unknown functions and regulatory enzymes.

(Submitter supplied) Plant defenses against pathogens and insects are regulated differentially by cross-communicating signaling pathways in which salicylic acid (SA), jasmonic acid (JA) and ethylene (ET) play key roles. To understand how plants integrate pathogen- and insect-induced signals into specific defense responses, we monitored the dynamics of SA, JA, and ET signaling in Arabidopsis after attack by a set of microbial pathogens and herbivorous insects with different modes of attack. more...

(Submitter supplied) Jasmonate (JA) is a plant hormone that controls trade-offs between plant growth and responses to biotic and abiotic stresses. Although recent studies uncover core mechanism for JA-induced responses in Arabidopsis thaliana, it remains elusive how plants attenuate those responses. We report here that a basic-helix-loop-helix type transcription factor named JA-INDUCIBLE MYC2-LIKE1 (JAM1) acts as a transcriptional repressor and negatively regulates JA signaling. more...

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. more...

(Submitter supplied) 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.
