Demonstrates how vanillin alters the bacterial community in cucumber rhizosphere, suggesting potential impacts on plant health.
Cucumber seedlings grown in soil from a grass field were treated with vanillin at 0.1 µmol/g concentration for 10 days. Its rhizosphere bacterial composition was analyzed by high-throughput sequencing of 16S rRNA genes on an Illumina Miseq platform. A total of 175,273 quality sequences were obtained and these were classified into more than 2,100 OTUs (Operational taxonomic units) at 97% sequence similarity. Principal coordinates analysis at the OTU level, based on both Bray-Curtis and UniFrac distances, showed that vanillin changed the composition of rhizosphere bacterial community in cucumber seedlings. Exogenous vanillin decreased the relative abundances of Firmicutes and Bacteroidetes phyla but increased the relative abundances of Actinobacteria, Chloroflexi, Gemmatimonadetes and Cyanobacteria. At the genus level, exogenous vanillin decreased the relative abundances of Clostridium sensu stricto 1, Lysobacter, Ohtaekwangia, Devosia and Pseudomonas spp., and increased the relative abundances of Streptomyces, Pedomicrobium and Pseudonocardia spp.
