Synteny between the chromosomes of A. chroococcum NCIMB 8003 (ordinate) and A.vinelandii DJ (ATCC BAA-1303).
The nucleotide sequences of the chromosomes of A. chroococcum NCIMB 8003 (ordinate) and A.vinelandii DJ (ATCC BAA-1303) (abscissa) were aligned using BLASTn. The red and blue diagonal lines show the slopes that would be obtained were each chromosome aligned against itself: red, A. chroococcum; blue, A.vinelandii.
Fig 2.
Comparison of the gene contents in the chromosomes of A. chroococcum NCIMB 8003 and A.vinelandii DJ (ATCC BAA-1303).
Genes present in both strains are shown in red (“core genes”) whilst the genes present in only that strain (“accessory genes”) are shown in blue. The genome dimensions are marked in bp.

Plasmid- and chromosomal genes involved in Corrin and Adenosyl cobalaimin (B12) uptake, salvage and biosynthesis in Azotobacter chroococcum NCIMB 8003.
A. The region of 16,967 bp from bp 64,013 to 80,225 in plasmid pAcX50f containing a contiguous cluster of genes for corrin synthesis. B. The regions of 12,882 from bp 1,777,467 to 1,789,349; 740,868 to 741,638 and 3,736,258 to 3,738,156 in the chromosome potentially containing genes for corrin and B12 uptake and salvage and the late steps in the synthesis of adenosyl cobalamin.

Physical and genetic map of plasmid pAcX50c from A. chroococcum NCIB 8003.
The map shows the arrangement of deduced genes in the sequence of the potential retro-conjugative plasmid pACX50c. The two clusters of contiguous tra and trb conjugation genes are shown in green and dark blue respectively. Genes for other functions are indicated as follows: replication initiation (trfA: red); partitioning and maintenance (pink), Type I RMS system (AchIII) (yellow); transposases (brown); DNA binding and repair (grey); unidentified or conserved unidentified genes (white).
