Figure 4From: Genome-wide identification and analysis of miRNA-related single nucleotide polymorphisms (SNPs) in riceIllustration of substitution types for SNPs that occur in rice pre-miRNAs. Arrows indicate the direction of single nucleotide mutation. The ancestral state of each SNP site was derived from the Rice Haplotype Map Project Database (Huang et al. 2012b).Back to article page
