| Description |
Variability of the beta-amylase gene in bread wheat, artificial amphidiploids, and derived introgression wheat lines was analyzed. Variation in homeologous beta-amylase sequences caused by the presence of MITE (Miniature Inverted-Repeat Transposable Element) and its footprint has been identified in bread wheat. The previously unknown location of MITE in Triticum urartu and T. aestivum L. beta-amylase gene has been found. These species have a MITE sequence in the third intron of beta-amylase, as opposed to Aegilops comosa and a number of other Triticeae species, which have it in the fourth intron. These two MITEs from Ae. comosa and T. aestivum were shown to have low identity scores. Miosa, an artificial amphidiploid, which has the M genome from Ae. comosa was shown to lose the MITE sequences. This loss might be caused by genomic shock due to allopolyploidization.
