Abstract：
:Pseudomonas strains were isolated from the rhizosphere of maize grown in yellow-red latosol from Rio de Janeiro, Brazil, to serve as a delivery system for heterologous genes and for risk assessment studies in tropical soils. Selected strains were modified by insertion of the cryIVB gene from Bacillus thuringiensis and tested for pathogenicity gene expression against larvae of a susceptible model species, Anopheles aquasalis. Modified strains Br8 and Br12 showed similar survival performance to their parental strains, and presented a viable density of 10(7) c.f.u./g dry soil 30 days after release. A strain of P. fluorescens (Br12) that presented positive results for gene expression and the best survival performance, was selected for risk assessment studies in soil microcosms.
