acI carotenoid-related genes in the genomic context. acI genomic contigs or genomes from clades A, B, and C are primarily labeled by shorthand notation (i.e., designation after “actinobacterium SCGC” or “int.metabat.”). Genes are arrows pointing in the direction of transcription. A slash indicates a contig boundary, which may or may not end immediately after the pictured gene, a vertical zig-zag indicates contig ends that have been manually paired, and a thick horizontal bar indicates a longer region of DNA not represented. Uncolored genes are neighboring genes that may or may not be functionally associated with the carotenoid-related genes. Boldface labels indicate a gene source for this study. Relevant Integrated Microbial Genomes (IMG) database locus tags for this study from AAA278-O22 are A278O22DRAFT_00003540 (proposed acyltransferase), A278O22DRAFT_00010590-10560 (crtA to crtD), A278O22DRAFT_00010530-10510 (crtE to crtB), A278O22DRAFT_00007000-6980 (crtYd to blh), and A278O22DRAFT_00001360 (actR).
