Hierarchical clustering of the 24,536 GCFs in marine prokaryotic genomes. Representation of the data (inner to outer layers): genome type and phylum level classification of organisms possessing the representative BGCs; the third and fourth layers indicate the class and novelty of GCFs; the outer three layers indicate the number of BGCs in each GCF, the average length of those BGCs, and the completeness of the representative BGCs. The proportions of each subcategory of GCFs were presented below the dendrogram
