✦ Synopsis

Sequence polymorphisms and phylogenetic relationships from different genomes of 25 diploid species in Triticeae (Poaceae) were evaluated by using the sequences of y-type high-molecular-weight glutenin promoter (y-HGP). The length of the amplified y-HGP sequences ranged from 845 to 915 base pairs (bp) in the 25 species of Triticeae. Multiple sequence alignment showed conserved and variable parts in the y-HGP sequences. Higher sequence conservation was detected in the regulatory elements of y-HGP. An 85-bp deletion was found in eight species of Triticum, Aegilops, and Hordeum. Several species-specific indels were identified in the y-HGP from Psathyrostachys, Hordeum, and Pseudoroegneria. Maximum parsimony (MP) and Bayesian analyses defined an Aegilops/Triticum group consisting of closely
