Abstract:
Restriction sites for six enzymes were mapped for the plastid DNAs of 25 species of Eragrostideae, one species of Cynodonteae ( Eustachys distichophylla ), and one species of Pooideae. Of the 124 restriction sites observed, 67 were variably present and shared by two or more species. These data were analyzed by the parsimony method using equal and unequal weights and by bootstrap analysis. The cladistic analyses established that members of the Muhlenbergiinae, including the genera Muhlenbergia, Blepharoneuron, Bealia, Chaboissaea, Lycurus , and Pereilema , share seven restriction site mutations and are strongly supported by the data as a monophyletic subtribe. Surprisingly, Redfieldia flexuosa also clustered with the Muhlenbergiinae in the analysis, perhaps indicative of a past interspecific hybridization event. The restriction sites data also weakly support a relationship (six shared mutations) between Erioneuron, Munroa , and Dasyochloa.
