  1. Groups of genes that are significantly enriched in at least one STEM profile at a FDR of < 5% are marked with an asterisk (*). The final column details the frequency of assignment of individual genes to specific STEM profiles identified by corresponding letters in Figure 2. Functional categories in this table are defined according to the following sources: proline and trehalose biosynthesis [23]; dehydrins [27]; ROS-network [33]; class III peroxidases [25, 102], GSTs [25]; MATE transporters [38]; aquaporins [25, 103]; all other transporters [25, 37].
