Enrichment of results, KEGG heatmap. (a) Signaling pathways in SARS-CoV-2; (b) signaling pathways in SARS-CoV-1. The blue color identifies a higher p-value and the red color a lower value (using a logarithmic transformation). A gradient of involvement of the signaling pathways, and therefore of the cells, is identified in both heatmaps from left to right (less altered to more altered, respectively).
