It’s time for another guest post today – Katherine Denby writes about the SEB 2012 conference.
Warwick Systems Biology Centre was well represented at the recent SEB conference in Salzburg, with 4 presentations in sessions on Biotic Stress, Environmental Control of Development and Generating New Biological Insights from Complex Data.
First up was Katherine Denby who presented analysis of a gene expression time series from Arabidopsis leaves infected with the fungal pathogen Botrytis cinerea generated in the PRESTA project. Using a variety of network inference algorithms, the group has generated models of the gene regulatory networks underlying the Arabidopsis response to this pathogen. These network models have highlighted specific regulatory interactions, and led to identification of transcription factors with a novel role in defence. Modelling using gene expression time series from other biotic and abiotic stresses has predicted a core regulatory network underlying multiple stress responses with differential flux through the network under different environmental conditions. Katherine also described a novel tool, Wigwams, to identify groups of genes significantly co-expressed across multiple stresses. Integrating this with the network models enables prediction of the upstream regulators of these groups. (more…)
