Hybrid watermelon fungi
High-throughput sequencing (Illumina MiSeq PE300 for bacteria, PE250 for fungi) targeting the bacterial 16S rRNA gene (primers 338F/806R) and fungal ITS region (primers ITS1F/ITS2R) was used to analyze rhizosphere microbial communities of diploid (HLL40-3), triploid (Guixi No.5), and tetraploid (MT410n-1) watermelons.
