Functional analysis of Cerrado soil metagenomes.

<p>The relative abundance of each gene functional category was based on MG-RAST analysis. All data were normalized for the quantity of assigned reads for (a) <i>cerrado denso</i>, (b) <i>campo sujo</i>, (c) cerrado <i>sens ustricto</i>, and (d) gallery forest soils. *P < 0.05 between the dry and rainy season.</p

Principal coordinates analysis (PCoA) plots were generated for bacterial, fungal, and archaeal communities to visualize differences between the dry and rainy season and the four Cerrado physiognomies.

<p>Analysis of soil bacterial community structure based on (a) unweighted UniFrac distance and (b) Canberra distance; soil archaeal community structure based on (c) unweighted UniFrac distance and (d) Canberra distance; and soil fungal community structure based on (e) unweighted UniFrac distance and (f) Canberra distance. Markers represent replicate soil samples collected during the dry and rainy season in <i>cerrado denso</i> (CD, square), <i>campo sujo</i> (CS, circle), cerrado <i>sensu stricto</i> (SS, triangle), and gallery forest (MG, diamond) soils.</p

Correlations between soil moisture content and relative abundance of the 12 dominant bacterial phyla in the Cerrado biome.

<p>Pearson correlation coefficients (r) are shown, with P values corrected using the Benjamini–Hochberg false discovery rate procedure.</p
