Schematic representation and comparison of the Nitrogen Fixation Islands and flanking genes of diazotrophic <i>P. stutzeri</i> strains A1501, DSM4166, B1SMN1, KOS6 and <i>P. azotifigens</i> DSM 17556.

<p>The nitrogen fixation island of <i>P. stutzeri</i> KOS6 was assembled downloading from the Integrated Microbial Genomes (IMG) (<a href="https://img.jgi.doe.gov/cgi-bin/w/main.cgi" target="_blank">https://img.jgi.doe.gov/cgi-bin/w/main.cgi</a>) three contigs (AMCZ01000041, AMCZ01000045 and AMCZ000005) indicated by brackets. The nitrogen fixation island of <i>P. stutzeri</i> strains B1SMN1 and <i>P. azotifigens</i> DSM 17556 were found in one contig. The colored of arrows are indicating different functional genes as described by IMG.
