Conserved litchi miRNAs. (a) Bar plot showing the number of conserved miRNA families and members identified from litchi pericarp. (b) Stem-loop structure of lch-miR159 precursor, which comes from litchi unigene No. 45530. Isoforms of lch-miR159, showing a variable number of uridines at the 5′ end, are detected with highly variable abundances
