Fig. 4From: Genome-wide identification of leaf abscission associated microRNAs in sugarcane (Saccharum officinarum L.)Polygenetic trees of six miRNA families. Polygenetic trees of pre-miRNAs, including (a) MIR156, (b) MIR160, (c) MIR166, (d) MIR167, (e) MIR171 and (f) MIR396, identified in this study and miRBase (v 21). MiRNAs with “(D)” are marked because they are sugarcane miRNAs recorded in current miRBaseBack to article page
