Summary
Two-dimensional gel electrophoresis of seedling proteins has been undertaken on diploid representatives of the A, S, and DTriticum genomes. The 457 reproducible spots of the hexaploid Chinese Spring were taken into account in the comparisons. More than 82% of the hexaploid spots were found among the representatives of each of the three genomes. Thus, it was proposed that the homoeologous structural loci, on the three homoeologous genomes, can be present in the same allelic forms and that from 72% to 86% of the spots of the hexaploid pattern are in two or three doses. The dendrogram, deduced from the similarity indices computed between the 16 diploid accessions, was very consistent with our present knowledge of the genetic relationships in theTriticum genus. This result, in addition to previous ones, shows that the comparison of two-dimensional protein patterns represents a novel experimental approach for studying the phylogenetic relationships in theTriticinae.
