Heatmap of differentially expressed miRNAs from M. truncatula roots treated with Nod and Myc-LCOs. Each column corresponds to the different treatments (Nod and Myc-LCO). IDs of differential miRNAs are indicated on the right of the diagram for each row. The tree at the top represents the grouping of the treatments based on the global expression pattern. Color gradients indicate the expression level for each miRNA: green, low; red, high. miRNAs were declared differentially expressed if the treatment P-value (adjusted for replication) was <0.05. P-values were adjusted to control the false discovery rate using the Benjamini-Hochberg method. Clustering was based on Pearson correlation coefficient and 'average' algorithm.
