Rhizosphere soil from intercropping barley (Hordeum vulgare L.) and paulownia (Paulownia elongata  Paulownia fortunei)
Genomic DNA was extracted from rhizosphere soil samples and the bacterial 16S rRNA gene was amplified using universal primers. Amplicon libraries were prepared following standard protocols and sequenced on the AVITI platform (Element Biosciences) using paired-end reads.
