Impact of Azospirillum sp. B510 on the Rhizosphere Microbiome of Rice under Field Conditions

There has been increasing attention toward the influence of biofertilizers on composition microbial communities associated with crop plants. We investigated impact Azospirillum sp. B510, a bacterial strain nitrogen-fixing ability, structure and fungal within rice plant rhizospheres by amplicon sequencing at two sampling stages (the vegetative harvest rice). Principal coordinate analysis (PCoA) demonstrated significant community shift in microbiome when plants were inoculated B510 stage, which was very similar to effect chemical N-fertilizer application. This result suggested that inoculation strongly influenced nitrogen uptake host under low conditions. Least discriminant (LDA) showed significantly increased N2-fixing Clostridium, Aeromonas Bacillus populations. In contrast, there no apparent structure. The putative functional properties bacteria identified through PICRUSt2, this hinted amino acid, sugar vitamin production might be related inoculation. Our results indicate recruiting other absence fertilizer.
