Secondary structures of the pre-miRNA region of Pto-MIR167a with single nucleotide polymorphisms (SNPs), and linkage disequilibrium within Pto-MIR167a, lncRNA gene ARFRL, and Pto-ARF8. (A) The secondary structures of Pto-MIR167a pre-miRNA sequence affected by two SNPs in the pre-miRNA region, and the minimum free energy of these secondary structures. (B) Pairwise correlations between SNPs (r²) are plotted against the physical distance between each SNP pair. The red curves indicate the nonlinear regressions of r² on the physical distance in base pairs.
