Plasmon and genome divergence at the diploid level in Triticum and Aegilops. (A) Plasmon relationships revealed by the present study. Number of lines connecting each pair (or group) of plasmons corresponds to their genetic distance (d) as follows: double, triple, quadruple, quintuple, and sextuple lines indicate d = 0.08–0.10, 0.06–0.08, 0.04–0.06, 0.02–0.04, and less than 0.02, respectively. Of 13 types and 4 subtypes of plasmon identified among the diploids, A type and three subtypes, C², S^l2, and T², are not shown in this figure, because A type was not studied, and the three subtypes are included in the respective main types, C, S^l, and T. (B) Genomic relationships. The number of lines connecting each pair of genomes corresponds to the modal number of bivalent chromosomes observed among the respective genomes (31, 32).
