Fishing for rDNA and ITS sequences aids study of Triticeae evolution
Using distribution patterns of rDNA in Thinopyrum ponticum and three diploid progenitors, Li and Zhang (pp. 445-452) conclude that during the evolution of T. ponticum, the position of rDNA in the genome is changeable while inherited interstitial loci are lost. Internally transcribed sequences show evidence of both interlocus and intralocus evolution.
