Heatmap depicting the expression level of the differentially expressed transcripts in individuals of the low microbial abundance species Haliclona vansoesti. On the left are listed the annotations obtained with the Swiss-Prot metazoan database and on the right are listed the annotations obtained with the Swiss-Prot prokaryotic database. The scale for relative expression values (log2 scaled) increases from blue to red. The functions of the annotated transcripts are grouped in categories and depicted by the different colors. AA, amino acids; FA, fatty acids; UNKW, unknown
