FIG 6.

(A) Mean relative abundances of the top 20 most abundant fungal genera in rhizosphere soil RNA, rhizosphere soil DNA, bulk soil DNA, root RNA, and root DNA. (B) Mean relative abundances of the top 20 fungal genera found in the ¹³C-RNA and ¹²C-RNA fractions in the rhizosphere soil and in the root fractions. Taxonomic classification of the ITS region was performed in QIIME using the UNITE reference taxonomy. (Note that more than 20 bars are displayed in each histogram, since the top 20 most abundant genera are not the same in different root/rhizosphere soil DNA/RNA fractions.)
