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 organisms）中物种多样性最高的类群之一。它们在绝大多数非海洋生态系统中发挥着关键作用，诸多昆虫物种具有极高的经济与医学价值。阐明昆虫的演化历程，对于理解陆地和淡水环境中的生命演化规律至关重要。1KITE（1K Insect Transcriptome Evolution，千种昆虫转录组演化）项目旨在对涵盖所有已确认昆虫目级类群的1000种昆虫的转录组（即表达基因的完整集合）进行研究。针对每个物种，研究将采用下一代测序技术（next generation sequencing techniques，NGS）获取表达序列标签（Expressed Sequence Tags，ESTs）。该预期数据将首次助力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。
