Relative nodule occupancy of several nodulating and nitrogen-fixing Burkholderia strains in four legumes. For each tested legume, the ratio of each bacteria in the initial inoculum is shown followed by the ratio obtained 21 (bean and cowpea) or 28 (mimosa and siratro) days post infection (dpi). A mixture of five Burkholderia strains – B. diazotrophica, B. mimosarum, B. phymatum, B. sabiae, and B. tuberum (mix 1) – was inoculated on bean (P. vulgaris) (A) and siratro (M. atropurpureum) (D). The same bacterial mixture excluding B. tuberum (mix 2) was applied onto cowpea (V. unguiculata) (B). For mimosa (M. pudica) (C) four Burkholderia strains were inoculated: B. diazotrophica, B. mimosarum, B. phymatum and B. symbiotica (mix 3). “N” indicates the number of analyzed plants and “n” the number of analyzed nodules.
