Rhizobacterial communities of four weedy plant species.

Selected rhizobacterial communities of the four weedy plant species Galium mollugo (Gal), Centaurea jacea (Cen), Echinochloa crus-galli (Ech) and Hordeum murinum (Hor). Each row represents a different bacterial strain. The ability to release cyanide (CN-) is indicated by Yes.aSpecies name given by API 20NE® identification system. If no clear identification was possible, the two or three most likely bacterial species names were recorded.bStrains used in the host-plant selectivity experiment.cStrain identified by DSMZ.dA-C: Strains differing in biochemical tests but identified as similar species.
