Fig. 1

Genome wide alignment of the 6 desert rhizobial draft genomes. The finished genome of Ensifer meliloti 1021 consisting of concatenated replicons in the order chromosome, pSymA and pSymB (indicated on the top of the figure) was first used as a reference to order the 79 scaffolds of LMR001 (a) using the progressive MAUVE aligner. The resulting reordered pseudo-assembled LMR001 genome was subsequently used as reference to reorder the scaffolds of LMR013 (b), LEM451 (c), LEM457 (d), TP6 (e) and TW10 (f). Scales above each map refer to genome size in million base pairs (Mbp). Scaffold borders are indicated by vertical red bars and locally collinear blocks are shown using similar colors across draft genomes. Colorless spaces indicate accessory genomic regions
