The 1KITE project: evolution of insects

Insects are one of the most species-rich groups of metazoan organisms. They play a pivotal role in most non-marine ecosystems and many insect species are of enormous economical and medical importance. Unraveling the evolution of insects is essential for understanding how life in terrestrial and limnic environments evolved. The 1KITE (1K Insect Transcriptome Evolution) project aims to study the transcriptomes (that is the entirety of expressed genes) of 1,000 insect species encompassing all recognized insect orders. For each species, so-called ESTs (Expressed Sequence Tags) will be produced using next generation sequencing techniques (NGS). The expected data will allow inferring for the first time a robust phylogenetic backbone tree of insects. Furthermore, the project includes the development of new software for data quality assessment and analysis.

昆虫是后生动物（metazoan）中物种多样性最为丰富的类群之一，在绝大多数非海洋生态系统中发挥着关键性作用，且众多昆虫物种具有极高的经济与医学价值。解析昆虫的演化历程，对于理解陆地与淡水生境中的生命演化过程至关重要。1K昆虫转录组演化计划（1K Insect Transcriptome Evolution，1KITE）旨在对涵盖所有已知昆虫目级类群的1000种昆虫的转录组（transcriptome，即全部表达基因的集合）开展研究。该计划将利用下一代测序技术（next generation sequencing, NGS）为每个物种生成表达序列标签（Expressed Sequence Tags, ESTs）。预期获取的数据将首次支持构建稳健的昆虫系统发育主干树。此外，本项目还将开发用于数据质量评估与分析的新型软件工具。
