Experimental validation of the miRNA targets.

<p>Cleavage sites were determined by the modified 5’RNA ligase-mediated RACE. Heavy black lines represent unigenes. miRNA complementary sites with the nucleotide positions of SPL and MYB cDNAs are indicated. Vertical arrows indicate the 5’ termini of miRNA-guided cleavage products, as identified by 5’-RACE, with the frequency of clones shown.
