Identification of sRNAs controlling the dominance–recessivity relationships: class II > class I. (a) Stem-loop structures of the S₁₃, S₁₆, S₁₄, and S₁₈ haplotypes of AlSMI1 predicted by RNAfold [20]. Black dashed boxes indicate 24-nt snRNAs corresponding to class-III and class-II AlSmi1-a. The predicted 24-nt mature AlSmi1-b is shown in red. (b) Schematic diagrams of the S locus in the S₁₄ haplotype (KJ772406) and S₁₈ haplotype (KJ772412). Green, yellow, and red boxes indicate SP11, SRK, and AlSMI1, respectively. (c) Schematic diagrams of the SP11 genomic regions of the S₂₀, S₁₃, S₁₆, and S₁ haplotypes. Black boxes indicate exon regions of SP11, orange boxes indicate the target regions homologous to AlSmi1-b. (d) Sequence similarity between AlSmi1-b and SP11. Numbers are the mispair scores between class-II AlSmi1-b and class-IV, class-III, class-II, and class-I S haplotypes of SP11. N.D., not detected. Mispair scores < 5.5 are shown in red.
