ABSTRACTAbout the characterization and distribution of novel nitrogen-fixing Burkholderia species associated with maize and other plants and their potential use on the plant growth was presented in this symposium. The symposium included studies directed to the re-vegetation of eroded areas by using plant growth promoting rhizobacteria and mycorrizal fungi associated with desert plants, as well as studies related with the resistance of arbuscular mycorrhizal fungi to heavy metals associated with the environmental pollution. In addition, the identification and characterization of a 31-kb chromosomal fragment from Pseudomonas syringae pv. phaseolicola was presented; such a fragment, involved with the phaseolotoxin synthesis, showed characteristic features of a bacterial pathogenicity island.
