Figure 5

Neighbor joining tree showing phylogenetic relationship of the sequenced DGGE bands. Total 1000 bootstraps were performed and only more than 50% bootstrap support values are mentioned. All the phylogenetic analysis was performed using MEGA4 software. Numbers designate the clades. Values in parentheses indicate the range of soil salinities (in ds m^-1) corresponding to the clade of cyanobacteria. For details of methodology refer materials and method section.
