Biodiversity of a Burkholderia cepacia population isolated from the maize rhizosphere at different plant growth stages

Article Abstract:

Biodiversity in Burkholderia cepacia, a bacterial species colonizing corn roots, was investigated using molecular as well as polymerase chain reaction-based techniques. The investigation was conducted by first isolating the organisms and assigning them to particular strains or species by restriction fragment length polymorphism criteria. Biodiversity was then analyzed by the random amplified polymorphic DNA method.

Growth interactions during bacterial colonization of seedling rootlets

Article Abstract:

Soil bacteria that produce siderophores and HCN can outcompete those that don't, according to a study of Pseudomonas colonization of cucumber and spinach seedlings. Siderophores are iron chelators produced by bacteria that are excreted to capture iron in a form that can be utilized by bacteria and plants.

Frequency and biodiversity of 2,4-diacetylphloroglucinol-producing bacteria isolated from the maize rhizosphere at different stages of plant growth

Article Abstract:

Researchers describe the isolation of a Pseudomonas species that naturally colonizes the roots of Zea mays and produces 2,4-diacetylphloroglucinol (DAPG). DAPG is a natural antibiotic against major plant pathogens.
