DNA barcoding of different Triticum species

Abstract

The phylogenetic tree obtained from both nucleotide and amino acid sequences divided the 20 Triticum species into two groups, A and B. Group A represented the diploid Triticum species. Group B was divided into two subgroup, I and II. Subgroup I represented the hexaploid Triticum species and subgroup II represented the tetraploid species. The matK gene sequence has a critical role in discriminating the closely related Triticum species. So these sequences could be used as a DNA barcode for detecting the evolutionary history of Triticum species.
