title: microbial sequences of bulk soil
design: Different maize genotypes were sown in the soil pots with natural soil with different fertilization regimes (control, low nitrogen, low phosphorus)  conditions for 4 weeks, and then rhizosphere soil and the root from the primary root, lateral roots, cortex and stele were harvested. The genomic DNA was isolated from those rhizosphere soil and roots and subjected to 16S rRNA gene V1-V9 sequencing. The RNA was isolated from roots and subjected to transcriptomic sequencing.
