Comparative Analysis of Fatty Acid Desaturases in Cyanobacterial Genomes
Figure 6
Neighbor-joining tree of Δ9-homologous
genes of cyanobacteria and eukaryotic algae. About 250 positions
spanning the three histidine-boxes were employed. Colored branches indicate different groups of proteins. Dark blue: Clade 1,
magenta: Clade 2, green: Clade 3, red: Clade 4, light blue: Clade 5, orange: Clade
6. Sequences
from 37 sequenced cyanobacterial genomes are shown by their acronyms and
accession numbers (locus tags). Other
sequences are shown by their accession numbers, labels, and strain names. Desaturase genes that have been functionally characterized are indicated on the tree by their labels.
Bootstrap values from neighbor-joining analyses are
listed to the left of each node, with values more than 50 are shown.
