Fig. 5: Paraburkholderia phylotypes were highly abundant in ¹³C-DNA recovered from DNA-SIP experiments in which ¹³C-pHB was added to field soils.

Paraburkholderia represented one-third of all phylotypes enriched significantly in ¹³C-DNA as determined by their log₂-fold differential abundance relative to corresponding ¹²C-DNA controls shown in (A). Paraburkholderia and Caballeronia phylotypes identified in (A) comprised the seven most relatively abundant phylotypes in ¹³C-DNA, and these phylotypes were found in all tree plantations, as shown in (B). The two most abundant ¹³C-labeled phylotypes matched P. madseniana RP11^T and P. xenovorans, respectively (B). Bars are colored by taxonomic classification and labeled with an abbreviated taxon name where bar coloring is obscured. Error bars correspond to standard deviation (n = 3). Phylotypes were designated to a species group based on the top representative BLAST hit to a type strain (100% identity). Details on the rank and relative abundance of phylotypes are available in Table S7.
