The tortoise and the hare II: relative utility of 21 noncoding chloroplast DNA sequences for phylogenetic analysis

TL;DR: The results of this study show that a survey using as few as three representative taxa can be predictive of the amount of phylogenetic information offered by a cpDNA region and that rate heterogeneity exists among noncoding cpDNA regions.

Ribosomal ITS sequences and plant phylogenetic inference.
Inés Álvarez,Jonathan F. Wendel +1 more
TL;DR: Despite the near-universal usage of ITS sequence data in plant phylogenetic studies, its complex and unpredictable evolutionary behavior reduce its utility for phylogenetic analysis, and it is suggested that more robust insights are likely to emerge from the use of single-copy or low-copy nuclear genes.
Journal ArticleDOI
Phylogenetic analysis of Sorghum and related taxa using internal transcribed spacers of nuclear ribosomal DNA.
TL;DR: The phylogenetic relationships of the genus Sorghum and related genera were studied by sequencing the nuclear ribosomal DNA (rDNA) internal transcribed spacer region (ITS) and it is indicated that S. arundinaceum race aethiopicum may be the closest wild relatives of cultivated sorghum.
Journal ArticleDOI
Age and rate of diversification of the Hawaiian silversword alliance (Compositae).
TL;DR: This work took advantage of rate-constant rDNA sequence evolution and an "external" calibration using paleoclimatic and fossil data to determine the maximum age and minimum diversification rate of the Hawaiian silversword alliance (Compositae), a textbook example of insular adaptive radiation in plants.
Journal ArticleDOI
Chloroplast DNA systematics: a review of methods and data analysis
TL;DR: Recent advances in experimental methods and data analysis, as applied to the chloroplast genome are reviewed.

Relationships between gene trees and species trees.
Pekka Pamilo,Masatoshi Nei +1 more
TL;DR: It is well known that a phylogenetic tree (gene tree) constructed from DNA sequences for a genetic locus does not necessarily agree with the tree that represents the actual evolutionary pathway of the species involved (species tree).
Journal ArticleDOI
Distinguishing Homologous From Analogous Proteins
TL;DR: This work provides a means by which it is possible to determine whether two groups of related proteins have a common ancestor or are of independent origin, and how many nucleotide positions must differ in the genes encoding the two presumptively homologous proteins.
