Title: Journey through the past: Computational techniques to unveil plant genome evolution

Time: Wed, Feb 8, 2012, 10am

Place: MPI für Molekulare Pflanzenphysiologie, Room 0.21 in The Box

With the number of plant genome sequences quickly growing, the need for a central repository increases. Hence, resources that collect data generated by different sequencing initiatives, in a uniform format, are becoming useful tools for data mining as well as powerful starting points for comparative analyses. Here PLAZA 2.5, a user-friendly platform that integrates 25 published plant genomes, will be presented. Besides the raw structural and functional annotation a variety of tools were run and results can be browsed through an intuitive website. Eg. all genes are grouped in gene families, for which multiple sequence alignments and phylogenetic trees are readily available, along with a variety of other tools. To allow users to efficiently explore the wealth of data contained in PLAZA 2.5, various custom visualizations have been developed. This allows even complex data, combining various types of information, to be presented in a comprehensible way.

A second part of the platform is dedicated to study genome evolution. Both rearrangements after speciation and the effects of ancient large-scale duplications can be studied. Regions derived from a common ancestor, essential to study evolution at the genomic level, were detected based on the conservation of gene content and order using i-ADHoRe 3.0 (a new version specifically designed for such large-scale datasets). PLAZA 2.5 and i-ADHoRe 3.0 therefore are useful tools for plant researchers worldwide and shows how modern large-scale approaches can be used for efficiently studying genome evolution in plants. (PLAZA 2.5 is available from i-ADHoRe 3.0 can be downloaded from Both tools are free for academic use.)
