Figure 2.

Genetic variation map showing haplotype sequences, single nucleotide polymorphism positions, and corresponding wheat varieties. Vertical bars represent polymorphic sites aligned to a gene diagram, with color-coded segments indicating genetic differences. Haplotypes and associated SSD numbers are listed, alongside varieties such as Colosseo, Svevo, Saragolla, Kronos, and Cappelli. Scale bar indicates 100 base pairs.

Haplotypes identified in TdBCAT promoters of 38 durum wheat genotypes. Haplotype 1 and Haplotype 6 are reference for TdBCAT-A and TdBCAT-B, respectively.
