Understanding plant genome organization and gene function is essential for modern plant biology research. This one-day workshop will introduce the basic concepts of comparative and functional-omics data analysis in plants through short kick-start lectures and practical hands-on sessions.Plant biologists and geneticists interested in bioinformatics and data analysis are encouraged to attend this training.  After this workshop, you will have a good understanding of the organisation of plant genomes, the evolution of plant gene families, orthologs and (in)paralogs, and the different systems used to describe gene functions. In addition, you will know how to extract relevant biological information from -omics gene sets using the PLAZA Workbench.
