ABSTRACT Rock phosphate is an alternative form of phosphorus (P) fertilizer; however, there no information regarding the influence P fertilizer sources in Brazilian Cerrado soils upon microbial genes coding for phosphohydrolase enzymes crop rhizospheres. Here, we analyze a field experiment comparing maize and sorghum grown under different fertilization (rock triple superphosphate) performance, phosphatase activity rhizosphere microbiomes at three levels diversity: small subunit rRNA marker bacteria, archaea fungi; suite alkaline acid phytase genes; ecotypes individual genes. We found significant difference performance between sources, but accumulation into pools organic soil differed. Phosphatase was only biological parameter influenced by fertilization. Differences were observed all biodiversity due to type, not Inspection gene responsible differences crops suggests role lateral genetic transfer establishing ecotype distributions. Moreover, they reflected community composition, suggesting that confer competitive advantage cells rather than species rhizosphere.
