Phylogeny and substitution rates of angiosperm actin genes.
Forty-four actin genes from five angiosperm species were PCR-amplified, cloned, and sequenced. Phylogenetic analysis of 34 of these actins, along with those previously published, indicates that angiosperm actin genes are monophyletic and underwent several duplications during evolution. Orthologues have been identified between Solanaceae species, as well as between Solanaceae species and soybean...

متن کاملAngiosperm phylogeny: 17 genes, 640 taxa.
PREMISE OF THE STUDY Recent analyses employing up to five genes have provided numerous insights into angiosperm phylogeny, but many relationships have remained unresolved or poorly supported. In the hope of improving our understanding of angiosperm phylogeny, we expanded sampling of taxa and genes beyond previous analyses. METHODS We conducted two primary analyses based on 640 species represe...
متن کاملThe root of angiosperm phylogeny inferred from duplicate phytochrome genes.
An analysis of duplicate phytochrome genes (PHYA and PHYC) is used to root the angiosperms, thereby avoiding the inclusion of highly diverged outgroup sequences. The results unambiguously place the root near Amborella (one species, New Caledonia) and resolve water lilies (Nymphaeales, approximately 70 species, cosmopolitan), followed by Austrobaileya (one species, Australia), as early branches....
متن کاملPhylogeny and comparative substitution rates of frogs inferred from sequences of three nuclear genes.
Phylogenetic relationships among major clades of anuran amphibians were studied using partial sequences of three nuclear protein coding genes, Rag-1, Rag-2, and rhodopsin in 26 frog species from 18 families. The concatenated nuclear data set comprised 2,616 nucleotides and was complemented by sequences of the mitochondrial 12S and 16S rRNA genes for analyses of evolutionary rates. Separate and ...
