Co-expression analysis of the LAC and PRX genes based on EucGenIE datasets. a Visualization of the co-expression network using exNet (default threshold = 5) and expression clusters using exHeatmap, for the initial set of LAC/PRX candidate genes; b GO enrichment analysis of the two main subnetworks using Enrichment. The exNet tool allowed the generation of a co-expression network based on 72 transcriptomic datasets across different tissues (exAtlas) and biotic conditions (interaction with Chrysoporthe austroafricana, Phytophthora cinnamomi and Leptocybe invasa). Nodes are coloured according to gene preferential expression across the six tissues in E. grandis x E. urophylla tissues (exAtlas) and edge thickness is proportional to the absolute correlation value. Heatmaps were created using the exHeatmap tool to visualize standardized values of absolute expression (VST) of genes across the nine tissues in the E. grandis tissues in exAtlas. Clustering of genes is based on the Ward method [79] and clusters are related to the main subnetworks. Biological process GO enrichment tests were performed using the Enrichment tool and coloured according to enrichment significance
