Relative abundance of gene families.

The 236,769 bacterial transcripts found to match reads were clustered into 13,278 gene families. The table indicates the relative abundance of each gene family as measured by summing RPKM values for each transcript in that family. Shown are the top 20 most abundant families in the NOD503CecMN sample together with the rank of abundance across all 12 samples. ‘Descriptions’ represent annotations associated with the transcripts according to definitions provided by Genbank. ‘Predominant taxon’ indicate the most frequent taxonomic group associated with the transcripts in the gene family.
