Multiple sequence alignment of x-HGP of 21 Triticeae diploid species and four species of Hordeum as outgroup. The species-specific indels were indicated by boxes, a, partial HMW enhancer appears in all x-HGP of all 21 species, but deleted in those of four Hordeum; b and c, d represent unique indels in Psathyrostachys and Aegilops. The inserted fragments in Psathyrostachys and Aegilops are duplication of adjacent region.
