Length distribution of MITE-miRNAs and MITEs in Zea mays and Sorghum bicolor. (A) Comparison of the length distribution of MITE-miRNAs and MITEs in Z. mays (top) and Sor. bicolor (bottom). Kernel density estimation with histograms is used to display the length distribution. (B) Comparison of the length distribution of MITE-miRNAs and MITEs from the PIF/Harbinger superfamily in Z. mays and Sor. bicolor. (C) Comparison of the length distribution of MITE-miRNAs and MITEs from the Tc1/Mariner superfamily in Z. mays and Sor. bicolor.
