From: Follow-up study of airway microbiota in children with persistent wheezing
A heatmap of the airway microbiota composition at levels of phylum (P), class (C), order (O), family (F), and genus (G). The innermost layer is the taxonomic tree labeled with background color, and the outermost layer is the annotated genus. The red globules indicated that there was significant difference between children with persistent wheezing and control group. The middle layer with red and yellow was a heatmap of average genus abundance, the darker the color, the higher the abundance
