The spider mite Tetranychus urticae is a cosmopolitan agricultural pest with an
extensive host plant range and an extreme record of pesticide resistance. Here we
present the completely sequenced and annotated spider mite genome, representing
the first complete chelicerate genome. At 90 megabases T. urticae has the
smallest sequenced arthropod genome. Compared with other arthropods, the spider
mite genome shows unique changes in the hormonal environment and organization of
the Hox complex, and also reveals evolutionary innovation of silk production. We
find strong signatures of polyphagy and detoxification in gene families
associated with feeding on different hosts and in new gene families acquired by
lateral gene transfer. Deep transcriptome analysis of mites feeding on different
plants shows how this pest responds to a changing host environment. The T.
urticae genome thus offers new insights into arthropod evolution and
plant-herbivore interactions, and provides unique opportunities for developing
novel plant protection strategies.
