Abstract excerpt
MicroRNAs (miRNAs) are important post-transcriptional regulators of their target genes in plants and animals. miRNAs are usually 20-24 nucleotides long. Despite their unusually small sizes, the evolutionary history of miRNA gene families seems to be similar to their protein-coding counterparts. In contrast to the small but abundant miRNA families in the animal genomes, plants have fewer but larger miRNA gene...
