摘要

The citrus red mite, Panonychus citri, is known for its ability rapidly to evolve resistance to insecticides/acaricides and to adapt to hosts that produce toxins. In this study, we constructed an unprecedented four gigabase pair transcriptome of P. citri, which was assembled into 64 149 unique transcripts, the functions of which were annotated by five public databases. A total of 116 unique transcripts were identified as representatives of potential involvement in the detoxification of xenobiotics. Genes recorded to encoding insecticide/acaricide target proteins were also obtained from the P. citri transcriptome. In order to explore novel candidate genes potentially involved in the pesticide detoxification of P. citri, we also constructed digital gene expression libraries of short-term transcriptome responses of P. citri to pesticides, which resulted in the identification of 120 unique transcripts potentially associated with insecticide/acaricide detoxification. Our study will facilitate molecular research on pesticide resistance in citrus red mites, as well as in other phytophagous mites.© 2012 The Authors.
