Metabolic Footprints of Sensu Lato Rhizosphere Bacteria Active against Maize Pathogens.

Consistent with their reported abundance in soils, several sensu lato strains were isolated from the rhizosphere of maize plants cultivated at different sites in central México. Comparative analysis of their 16S rRNA gene sequences permitted their separation into three distinctive clades, which were further subdivided into six other clusters by their close resemblance to (1) ; (2) , , and ; (3) ; (4) ; (5) , or (6) representative species. Direct confrontation assays revealed that these strains inhibited the growth of pathogenic f.

Burkholderia cepacia XXVI siderophore with biocontrol capacity against Colletotrichum gloeosporioides.

Colletotrichum gloeosporioides is the causal agent of anthracnose in mango. Burkholderia cepacia XXVI, isolated from mango rhizosphere and identified by 16S rDNA sequencing as a member of B. cepacia complex, was more effective than 6 other mango rhizosphere bacteria in inhibiting the model mango pathogen, C.
