(2011), particularly with regard to the following topics: 1. Several new species of Burkholderia have been described, and we shall put them into context with regard to their legume hosts and their geographical distribution, and also to evaluate how they might (ormight not) assist in current attempts to divide the genus Burkholderia into two new genera, separating the ?pathogenic? from the ?beneficial? species (see also Chapter 89). 2. It is now clear that Cupriavidus symbioses are not confined to C. taiwanensis, and in addition to soil factors (such as pH and the presence of heavy metals) there are possible geographical and plant phylogenetic factors underlying these symbioses. 3. Evaluation of potentially new ?rhizobial? taxa within the Betaproteobacteria (see also Chapter 89). 4. Coevolution between beta-rhizobia and their legume hosts, with particular reference to the Mimosoideae.  aBurkholderia  aMicrosymbionts  aDistribuição Geográfica  aEstirpe  aNodulação  aSimbiose  aMimoseae  aRizóbio  aStrain diversity1 aJAMES, E.
