The small RNA diversity from Medicago truncatularoots under biotic interactions evidences the environmental plasticity of the miRNAome

First column indicates the chromosome number. For each chromosome, the total number of SNPs, precursors, precursors with at least one SNP, precursors with at least one SNP in the mature miRNA sequence and precursors with a SNP at position 10 or 11 in mature miRNA are indicated for the conserved or novel miRNAs. Below, the percentage of precursors in each category is shown.
