Calendar Name: seminars Scheduled for: Thursday, November 29 2012, 11:00 - 12:30 Event text: Prof Kathleen Marchal VIB, Dept. of Plant Systems Biology Ghent University Gent Dept. of Microbial and Molecular Systems K.U.Leuven Leuven BELGIUM Details: �Systems Biology: Network-based data integration� ABSTRACT In current wet-lab practice high-throughput expression profiling techniques are used to find components of response pathways, e.g. mRNA profiling focuses on identifying genes that are differentially expressed following stimuli or ChIP-chip techniques are being used to identify TF-target interactions. With the availability of next-gen sequencing, complete genotyping in combination with expression analysis allows finding genetic loci underlying interesting phenotypic traits. Each of the experiments mentioned above eventually results in a list of candidate genes or loci that all relate to the same phenotype of interest. Computational analysis of such unstructured lists will in most cases be restricted to a simple functional enrichment analysis to elucidate the potential pathways or functions the candidate genes belong to or to identify functionally related gene sets, but the interactions between the identified candidate genes or their role in the global molecular network of the cell remains unknown. To get a more structured insight in these results, we focus our research on developing tools that allow analyzing dedicated in-house experimental expression data and interrogating them with publicly available omics data.

Calendar Name: seminars Scheduled for: Thursday, November 8 2012, 11:00 - 12:30 Event text: Dr Pierre Rouz� VIB, Dept. of Plant Systems Biology Ghent University Gent BELGIUM Details: �Of Mamiellales, the green yeasts, as models for Plant Systems Biology, and of mobile introns� ABSTRACT The interest of plant scientists for Mamiellales, comes from the assumption that the ancestor to all other Viridiplantae was part of it. Mamiellales are widespread marine picoplankters and the complete genome sequence has been obtained for six of these unicellular green algae, including Ostreococcus (x3) , Micromonas (x2) and Bathycocus, all of these annotated by our group in Ghent. These genomes are small, from 13 to 22Mb, harboring from 7.500 to 10.000 genes showing no duplication in most cases. Added to easy cultivation and replacement mutation, these features makes these algae, especially the tiny Ostreococcus tauri, an interesting model to study gene networks for the traits which are conserved within the green lineage, bringing a frame on which to branch the duplication complexity of higher plants, in the same way yeasts are used towards animals. The sequenced genomes of Mamiellales have a unique heterogeneity, two chromosomes having specific features compared the rest of the genome, which may be related to sex and speciation. I will also present and discuss in this talk the unexpected observation that the genomes of the two Micromonas species which have been sequenced harbor many invading introns which are copies of each other, and are inserted at novel positions in the genes. This was the first observation of this kind of event; it illuminates the way intron can be gained, and shakes the current assumption that introns have been acquired at the birth of eukaryotes and have essentially been lost since.
