Heat maps of generally pathogen-regulated orthologues in wheat and barley in Puccinia interactions. Differentially expressed genes (DEGs) of wheat in Puccinia interactions were filtered for assignment to DEGs of barley in Puccinia interactions. On the median-centered normalized signal intensities (c: control, h: host interaction, n: nonhost interaction), a hierarchical clustering (Pearson correlation, average linkage) was performed with the software Genesis [88]. The median-centered signal intensities of barley orthologues were sorted accordingly and illustrated in a heat map. Clusters were named with letters and investigated for over- or underrepresentation of functional categories using MapMan ORA tool [35, 36]. All probes assigned to orthologues in the other species were taken as reference. The log ratio of presentation in the cluster and in the reference is given for BINs found to be significantly over- or underrepresented according to Fisher Exact Test (BINs comprising 5 or less probes of the cluster were excluded).
