Moreover, the hierarchical clustering heat map shows 5 two-genes-clusters between GST1-PAL1, PR5-PR2, AFPRT-PR12, PR3-PR1, and SbWRKY19-JERF3. In general, the hierarchical clustering expression exhibited high up-regulation of the investigated genes in case of the infection treatments, whether treated with lavender EO or not. Here, PRTN3 is linked to infection.
