Siderophore Production Capability of Nitrogen-Fixing Bacterium (NFB) GXGL-4A Regulates Cucumber Rhizosphere Soil Microecology.

ABSTRACT: Many nitrogen-fixing bacteria can produce siderophores for iron acquisition in soil, but the impact of their siderophore-producing capabilities on the rhizosphere soil microecology is not well understood. To explore the effects of root inoculation with NFB strains with different siderophore-producing capabilities on the rhizosphere soil microecology and deeply evaluate the application value of a high-yielding siderophore strain in promoting crop growth, the wild-type nitrogen-fixing bacterial strain Kosakonia radicincitans GXGL-4A and its Tn5 mutants M107 (high siderophore-producing ability) and M246-2 (deficient in siderophore production) were used as biofertilizers in cucumber rhizosphere soil. Iron is important for the growth of bacterial cells, and the mutant M246-2 showed the s
