Identification of TaSPL14-7A haplotypes and development of molecular markers. The top panel shows a schematic diagram of the gene and 2.5 kb promoter structure of TaSPL14-7A. The ATG start codon was designated as position 1 bp. The bottom panel shows the polymorphic sites of TaSPL14-7A. A CAPS marker named CAPS-144 was developed based on the SNP (T/C) at 144 bp. Digestion of the amplified 421 bp fragment with MseI produced fragments of 238 bp and 183 bp for TaSPL14-7A-Hap3 (T), whereas this fragment could not be digested for TaSPL14-7A-Hap1/2 (C). A CAPS marker named CAPS-4111 was developed based on the SNP (G/A) at 4111 bp. Digestion of the amplified 276 bp fragment with BglI produced fragments of 220 bp and 56 bp for TaSPL14-7A-Hap2/3 (G), whereas this fragment could not be digested for TaSPL14-7A-Hap1 (A).
