he Illumina NovaSeq PE250 platform was used for 16S rRNA sequencing analysis and strain identification (Beijing Boao Biotechnology Co., Ltd., Beijing, China)
Mean percentages and standard deviation of bacteria present at baseline annotated to the level of phylum, family, and genus, based on sequencing of 16S rRNA genes.
Bacterial 16S sequence data (primers 799F and 1115R) from the roots of maple seedlings. Sequences are in the fasta format, have been adapter-trimmed, and assembled.
