Plant root exudates and rhizosphere bacterial communities shift with competitive neighbor
Soil DNA was extracted with MoBio PowerSoil DNA extraction kit (MOBIO Laboratories, Carlsbad, CA, USA).  We targeted the bacterial V4 region of the 16S rRNA gene (primers 515f/806r) with MiSeq Illumina (V2) paired-end sequencing, conducted by the Research Technology Support Facility Genomics Core at Michigan State University, East Lansing, Michigan.
