Nucleotide divergence rates (dN/dS) of CBF-A15, VRN-A1, VRN-B3 and PPD-B1 genes and homologue amino acid sequences. a Nucleotide divergence rates (dN/dS) between the identified haplotypes of CBF-A15, reference sequence of T. aestivum and eight homologous plant AA sequences. The black line on top indicates the PKK/RPAGRxKFxETRHP motif and DSAWR, the red line the AP2 domain. The black arrows and clamp label the position of AA changes based on significantly associated SNPs and indels. The black line shows the dN/dS ratio. The red dots illustrate sites underlying significant negative selection (P < 0.05). b Nucleotide divergence rates (dN/dS) between the identified haplotypes of VRN-A1, reference sequence of T. aestivum and eight homologous plant AA sequences. The black line on top indicates the MADS box and K domain, the red line the I and C domain. The black arrow labels the position of AA change based on significantly associated SNPs. The black line describes the dN/dS ratio. The red dots indicate sites with significant negative selection (P < 0.05). c Illustrated are nucleotide divergence rates (dN/dS) between the identified haplotypes of VRN-B3, reference sequence of T. aestivum and eight homologous plant AA sequences. The black line on top indicatesthe segment B, the red line the flowering time (FT)-family protein. The black arrow labels the position of AA change based on significant associated SNPs. The black line describes the dN/dS ratio. The red dots illustrate sites with significant negative selection (P < 0.05). d Nucleotide divergence rates (dN/dS) between the identified haplotypes of PPD-B1, reference sequence of T. aestivum and eight homologous plant AA sequences. The black line on top indicates the Pseudo-Reciver domain, the red line the CONSTANS motif. The black arrows label the position of AA changes significantly associated SNPs. The black line describes the dN/dS ratio. The red dots indicate sites with significant negative selection (P < 0.05)
