Flow cytometry analysis of bacteria recovered from the root surface and nodules of plants infected with CFNX182-1. Plants were inoculated with strain CFNX182-1, which carries a RFP marker on the chromosome and a GFP marker on the pSym. Bacteria were recovered at 20 dpi from: (A) the medium, (B) the root surface and (C) nodules. Populations corresponding to donors (D) show red plus green fluorescence, putative endophytic recipients (PE) have no fluorescence, transconjugants of endophytic recipients (T) carry GFP and show green fluorescence, and pSym-cured derivatives (C) with RFP show red fluorescence.
