microbial sequences of maize root: crown root
Different maize genotypes were sown in the soil pots with natural soil with different fertilization regimes (control, low nitrogen, low phosphorus and drought)  conditions for 4 weeks, and then rhizosphere soil and the root from the 1st whorl of crown roots were harvested. The genomic DNA was isolated from those rhizosphere soil and roots and subjected to 16S rRNA gene V4 sequencing and ITS gene sequencing.
