Colonization of the roots of hydroponically grown rice plants by Bv and Pk. (A) Population dynamics of DsRed-tagged Bv and Pk associated with rice roots and inside the plant roots. The data reported are the median of bacterial population size from 18 plants and two independent experiments for rhizosphere compartment and five plants for the endophytic compartment. The letters indicate the significance groups in each compartment according to post-hoc tests on a generalized linear model. Epifluorescence microscopy pictures of the colonization of rice primary roots at 7 days postinoculation by Pk (B) and Bv (C) DsRed cells. White bars represent 200 µm. Bv, Burkholderia vietnamiensis TVV75^T; Pk, Paraburkholderia kururiensis M130.
