Phylogenomics and the evolution of insects - The 1KITE project


1KITE (1K Insect Transcriptome Evolution) is an international initiative that aims to study the transcriptomes of 1,000 insect species encompassing all recognized insect orders (www.1kite.org). We will address the phylogeny of insects by analyzing an unprecedented amount of nucleotide sequence data, allowing us to reconstruct the major character transformations and timing of diversifications in their evolution.. Scientists involved include experts in molecular biology, insect morphology, taxonomy, paleontology, embryology, bioinformatics, and scientific computing from eight nations (Australia, Austria, China, Germany, Japan, Mexico, New Zealand, and the US). 1KITE is divided into several subprojects focusing on specific phylogenetic groups, for example, apterygote hexapods, Odonata, Polyneoptera, Hymenoptera, Trichoptera, and Antliophora. Additionally, 1KITE includes the development of new software for data quality assessment, phylogenetic reconstruction, and molecular dating. Sequencing will be completed by the end of 2012. Preliminary analyses of the already available sequences show that the obtained data are of yet unparalleled size and quality. We were able to identify ~ 1500 1:1 orthologous genes for every hexapod transcriptome we sequenced and first results show that inferred trees have the potential to deliver a plausible backbone tree of insects with robust statistical support. The results can be expected to have an extraordinary and long-standing high impact on entomological and phylogenetic research.
