Conteúdo: | Randomly Amplified Polymorphic DNA (RAPD) methods have been adapted for use as a phenetic tool on the legume tribe Cassiinae. RAPD-generated polymorphism within local populations was lower than between populations from different geographic regions, between species and genera. Examination of three Cassia species, 12 Chamaecrista species and 13 Senna species using eight primers showed the potential for separation of the nodulated/nitrogen fixing genus Chamaecrista from the previously congeneric groups Cassia and Senna. Similarly, RAPD analysis of two groups of nine Ch. rotundifolia and nine Ch. mimosoides samples using 11 primers has given separation according to both species and to geographical location. Analysis of a small sample of five Chamaecrista species from Brazil with eight primers gave separation consistent with known variations in nodule structure.
