Fig. 3

Novel biosynthetic gene clusters (BGCs) and their distributions in food fermentations. A BiG-SLiCE distance of BGCs in different BGC types compared with BGCs from FAM database. The red and blue dotted lines represent the BiG-SLiCE distances of 900 and 1800, respectively. The black lines in the boxplots are the average BiG-SLiCE distances of different BGC types. B The amount of novel BGCs from different BGC types in different food fermentation types. The numbers in the heat map represent the novel BGC counts. C Taxonomic origin of novel BGCs. The triangles and circles represent BGCs and bacterial species, respectively. The size of the circle represents the BGC number in the respective species. BGCs that are not included in the 8 dominant BGC types are combined and shown in Others. Species that are not included in the 13 BGC-rich families are combined and shown in Others
