Fig. 2From: Diurnal cycling of rhizosphere bacterial communities is associated with shifts in carbon metabolismRelative abundances of different organic compounds identified by 21T FT-ICR-MS. The volcano plot was obtained by plotting the log2 fold change on the x-axis and –log10(P) on the y-axis. Compounds that changed twofold or more with a P value <0.05 are indicated in pinkBack to article page
