Bacterial community of different ecophysiographic regions from Pernambuco, Brazil

In Brazil, the Pernambuco State presents three distinct ecophysiographic regions with contrasting soil conditions. In these regions, the most variable soil conditions are soil pH, fertility (macro and micronutrients, and organic matter), temperature, and annual rainfall. Particularly, these regions are important to produce cowpea (Vigna unguiculata), a special type of legume species used as a protein source to the local population. We assessed the bacterial community structure and composition through 16S rRNA sequencing of the regions Mata, Agreste, and Sertao.
