Quantification of 16S rRNA and nifH genes copies in samples taken from different organs of sweet sorghum plants (cv. M81E) grown in the field under high (+) and low (−) N fertilization (100 and 0 kg N ha−1, respectively). Means within two treatments that have the same letter are not significantly different by Tukey test with a .
