摘要: The chloroplast genomes of 44 accessions ofSecale were surveyed for restriction site polymorphisms. chosen to represent the geographic as well taxonomic range genus. Using 12 enzymes a total 348 sites detected. Twenty-nine mutation phylogenetically informative and used in cladistic analysis. Further, 0.1 kb insertion separatedSecale from outgroup species. Only annual speciesS. sylvestre was distinct rest taxa. Cultivated rye together with both wild perennial mixed among each other. Sequence divergence (p) taxa low, varying 0.000 0.005, suggesting rather recent origin
