Molecular Phylogenetics of Bromus (Poaceae: Pooideae) Based on Chloroplast and Nuclear DNA Sequence Data
We conducted a phylogenetic analysis to characterize relationships among Bromus and test the monophyly of five of the seven morphologically distinct groups within Bromus (Poaceae: Pooideae) that have been treated as sections, subgenera, or genera. We sequenced the chloroplast trnL (UAA) intron, the 3!-end of the chloroplast ndhF gene, and the internal transcribed spacers (ITS) of the nuclear ri...
متن کاملEragrostis (Poaceae): Monophyly and Infrageneric Classification
Eragrostis is a large genus in subfamily Chloridoideae of Poaceae. Recent phylogenetic analyses have suggested that the genus may not be monophyletic, that some of its segregate genera may be better placed within Eragrostis, and that current infrageneric classifications may not represent monophyletic groups. We have used molecular sequence data from the plastid locus rps16 and the nuclear gene ...
متن کاملSystematics of California Grasses (Poaceae)
The grass family (Poaceae or Gramineae) is the fourth largest flowering plant family in the world and contains about 11,000 species in 800 genera worldwide. Twenty-three genera contain 100 or more species or about half of all grass species, and almost half of the 800 genera are monotypic or diatypic, i.e., with only one or two species (Watson and Dallwitz 1992, 1999). Over the last 150 years th...
متن کاملMolecular diversity, structure and domestication of grasses.
Over the last 10,000 years, crop domestication has been the single most important human cultural development. Grasses are prominent among these crops, and provide the vast majority of the world’s food. Similar traits have been selected during the domestication and breeding of these critically important grasses, and since they share a similar complement of genes, the same set of genes may have b...
