| The two-spotted spider mite, Tetranychus urticae is one of the most important pests in agriculture, feeding on a broad range of plants worldwide. Spider mite short generation time and high fecundity rates produce an exceptional ability to develop pesticide resistance. Our group is a cofounder of the international consortium, GAP-M (Genomics in Agricultural Pest Management), composed by researchers from different scientific institutions, involved in the plant-spider mite interplay. The consortium has demonstrated a proliferation of detoxifying genes and digestive enzymes in the genome of the spider mite that allow its feed on many hosts (Gribc et al. 2011; Santamaria et al. 2012a). In this scenario, it is crucial to implement alternative control systems to confer plant resistance against mite attack. T. urticae is able to rear on Arabidopsis plants which offer important advantages for basic research in genetics and molecular biology. Upon infestation, plants activate a complex signalling network to generate defence at different levels combining constitutive with inducible defences. Based on the transcriptome results previously generated by the consortium using resistant and susceptible accessions (Zhurov et al. 2014), candidate genes putatively involved in plant defence against spider mite have been selected. Phenotype bioassays with T. urticae have been shown the in vivo function of these genes in plant defence (Santamaria et al. 2012b). Different molecular and biochemical analyses have been done in order to reveal gene function. | |
