  1. Final abundances determined by selective plate culture of Paraburkholderia phytofirmans PsJN, Cupriavidus pinatubonensis JMP134, C. metallidurans CH34, and C. taiwanensis LMG19424 after growth on A. thaliana root exudates (PRE) collected at day 14, or 21, with plants exposed to standard or N-limiting conditions: 14d.PRE, 21d.PRE, 14d.N-PRE, and 21d.N-PRE. Each value represents averages, and standard deviations from three replicates
