Rhizobacteria have been used as biocontrol agent of many soil-borne pathogens as well as phytohormone plant - producers of several plants including legumes and promoting increase of root area and nodulation. In this work we evaluated the effect of a fluorescent Pseudomonas sp. strain, isolated from the rhizosphere of common bean, on the structure of nodules formed by strains of R. leg. bv. phaseoli and R. tropici. Nodules formed solely by rhizobia strains were pink while they appeared greenished when rhizobacteria were coinoculated. The presence of the rhizobacteria was confirmed by plate counting and fluorescence production when nodules were exposed to UV light. Light microscopy sections from nodules originated from the coinoculation with rhizobacteria showeda small amount of infected cells. These cells were not fully occupied by the bacteroids and in addition they were not enclosed in a membrane envelope (peribacteroid membrane). In general, the bacteroids appeared free in the host cell. |
