Genomics and bioinformatics in plants and fungi

Genomics

Plant and fungal genomes are very dynamic and evolve much more rapidly than animal genomes. We are investigating the molecular mechanisms that drive this rapid evolution. Genomes are expanded by the amplification of transposable elements. The expansion of genomes is counteracted by deletion of DNA. We compare gene content, gene order and repeat content of different species. Comparative analysis is a powerful method to discover mechanisms that drive the evolution of genomes. We have so discovered mechanisms that cause gene duplications, gene movement and gene loss.

Using comparative genomics and transcriptomics, we also study interactions of plants and microbes. This includes plant/pathogen interactions as well as symbioses. We were involved in sequencing and analysis of the genome of wheat powdery mildew and the study of genetic diversity of the pathogen. Additionally, we study symbiotic systems such as lichens and the symbiosis of Psychotria plants with Burkholderia. An important focus of our work is the development of bioinformatics tools that allow complex analyses on large datasets for whole-genome analysis, comparative genomics and data visualization.
