Mature sequences of VvmiR160s and the secondary structures of their precursors. a The PCR products of 3′-miR-RACE and 5′-miR-RACE for VvmiR160a/b/c/d/e, respectively, and the cloning of their primary sequences. b Comparison of our cloned VvmiR160s precise sequences with the homologous sequences in grapes from MiRBase. c The secondary structures of VvmiR160s precursors, where red frames indicate the mature sequences of VvmiR160s at the 5′-end arms of their precursor structures
