| Abstract: | Restriction site polymorphism in cpDNA of 35 legumes was studied in order to address natural relationships and geographic distribution within the tribeGenisteae. 386 sites were studied, 277 were polymorphic, 207 were informative. Phylogenetic inferences with distance and parsimony methods suggest that the American and MediterraneanLupinus species belong to a monophyletic group which arose from a single center of diversification. The data furthermore indicate thatLupinus should not be included in the tribeGenisteae since at the level of cpDNA polymorphismAnagyris foetida (tribeThermopsideae) appears more closely related to otherGenisteae thanLupinus does. |
