Comparative Analysis of Fatty Acid Desaturases in Cyanobacterial Genomes

Figure 1

Phylogenetic tree of the sequenced cyanobacterial strains. A Neighbor-joining tree for 33 sequenced cyanobacteria constructed based on 16 S rRNA as was described in Section 2 and about 1300 positions were employed. To maximize the number of sites available for analysis, three partial sequences from Synechococcus sp. RS9917 (170 bp), Synechococcus sp. RS9916 (865 bp), and Synechococcus sp. BL107 (296 bp) were excluded. Moreover, no 16 S rRNA sequence was found in Cyanothece sp. CCY0110.
