Haloquadratum walsbyi : Limited Diversity in a Global Pond

Figure 3

Comparison of circular plasmids PL6A (6,129 bp) and PL6B (6,056 bp).

Predicted ORFs are labeled with their locus tags, and arrows represent their orientations and lengths. Nucleotide positions are given above each plasmid. Nucleotide similarity is indicated by the bar chart below the alignment (bar height and darkness of colour indicate the level of nucleotide identity, with solid black indicating 100% identity). The vertically oriented arrowhead at around 3.2 kb indicates a sharp break in homology. Percentage identity values of the corresponding protein sequences (in red) are given between ORFs in the alignment. H-T-H, helix-turn-helix protein domain. TM, transmembrane domain. Solid black arrowheads represent short repeat sequences (see text). The lowest panel shows the cumulative CT-skew plots of both sequences.
