Soil Acidobacterial 16S rRNA Gene Sequences Reveal Subgroup Level Differences between Savanna-Like Cerrado and Atlantic Forest Brazilian Biomes

Figure 4

Principal component analysis (PCA) of soil acidobacterial 16S rRNA gene libraries. A matrix of variation-covariation was performed on PAST to analyze acidobacterial 16S rRNA gene sequences from the following areas of Cerrado (SA): “Mata de galeria” (MG), “campo sujo” (CS), “Cerrado sensu stricto” (SS), “Cerrado denso” (CD); “Serra dos Órgãos” (SO): sites 1 to 6 (S1, S2, S3, S4, S5, S6); “Serra do Mar” (SM): MA01, MA02, MA03, MA04, MA05, MA06, MA07, MA08, MA09, MA10. (a) Analysis based on the soil physicochemical characteristics for all sites. (b) Analysis based on the relative abundance of subgroups of Acidobacteria for all sites. Each vector points to the direction in which the respective value increases.
