Fig. 2From: Heterologous production of novel and rare C30-carotenoids using Planococcus carotenoid biosynthesis genesPhylogenetic trees of the crtN-related and crtM-related genes. Amino acid alignments and phylogenetic trees were constructed using MAFFT (http://www.mafft.ccbrc.jp/). A Phylogenetic tree of the crtN-related genes. The accession numbers of these sequences are shown in Additional file 1: Table S2. Orf1 and orf4 belonged to the crtNa and crtNb groups, respectively. B Phylogenetic tree of the crtM-related genes. The accession numbers of these sequences are shown in Additional file 1: Table S3. Orf3 belonged to the crtM groupBack to article page
