Figure 2. Northern Blot Analysis of the Conserved miRNA Families and the Newly Identified miRNAs in Cotton Ovules at –3, –1, 0, +1, and +3 dpa from Wild-Type Upland Cotton and the fl Mutant, Respectively. The numbers under the blots indicate the relative abundance of miRNAs, which was calculated using U6 as a loading control.
