Comparison analysis in German chamomile, Roman chamomile and other studied species (a) Unigenes comparison between German chamomile and Roman chamomile. Protein sequences from German and Roman chamomile were compared, > 80% of the length of each gene in a pair of homologous genes was strictly aligned, and sequences with > 70% homology were identified as homologous genes. The remaining sequences were identified as special transcripts in the German and Roman chamomile transcriptomes. b Analysis of gene families in two chamomiles and other studied species. The histogram on the left represents the number of gene families identified for each species, and the histogram above shows the number of common gene families among line connected species. Red color represents gene families specially presented in German and Roman chamomile. c Phylogenetic tree of two chamomiles and other studied species based on single-copy genes. The phylogenetic tree was constructed by FastTree (2.1.10) and the number on the node represents the bootstrap value. d Pfam domain enrichment analysis of genes families in German chamomile, Roman chamomile and other studied species using Fisher’s exact test. The color represents gene numbers in each species
