RiboSNitches landscape in tetraploid Kronos. a Scatter plot showing the correlation between experimental structure disruption coefficient (eSDC) and single-nucleotide variations (SNV) between A and B subgenome. b Statistics of nucleotide transition or transversion for riboSNitches. c Bar plot showing the ratio of riboSNitches relative to the SNVs at different genic regions. d Comparison of conservation ratio between riboSNitch SNVs and non-riboSNitch SNVs at different genic regions, data collected from 13 accessions of tetraploid T. turgidum spp. durum , error bar indicates se (P values, 0.002, 0.005, and 0.017 for 5′UTR, CDS and 3′UTR, respectively, by Student’s t test).
