There were six loci being located initially in all. The structural genes of Est E5 and Est E8 were located in 3EL, β Amy 1 in 4EL, Per E1 in 7E, and Per E4 in 5E. The α Amy E1 was relocated in 6EL. Chromosome location of these genes provide evidence of homoeology between wheat groups 3, 4, 6 and Agropyron elongatum chromosome 3E, 4E, 6E, respectively. It also indicated that chromosome rearrangement probably took place between 1E and 7E chromosomes during the evolution of the E genome.展开更多
