Properties of free-living cultured Bradyrhizobium sp. ORS285 bacteria and ORS285 bacteroids isolated from A. afraspera or A. indica nodules. A, Normaski bright-field (BF; top row) and fluorescence microcopy of bacteria and bacteroids stained with 4′,6-diamidino-2-phenylindole (DAPI; middle row) and PI (bottom row). Bars = 1 µm. B, DNA content of DAPI-stained bacteria and bacteroids measured by flow cytometry. Colors are as follows: blue, free-living bacteria; green, bacteroids isolated from A. afraspera; and red, bacteroids isolated from A. indica.
