The complete chloroplast genome sequence of Pelargonium xhortorum: Or ganization and evolution of the largest and most highlyrearranged chloroplast genome of land plants
Timothy W. Chumley,Jeffrey D. Palmer,Jeffrey P. Mower,H. Matthew Fourcade,Patrick J. Calie,Jeffrey L. Boore,Robert K. Jansen +6 more
TL;DR: The chloroplast genome of Pelargonium e hortorum has been completely sequenced as mentioned in this paper, and it is shown to contain two copies of a greatly expanded inverted repeat of 75,741 bp each, and consequently diminished single copy regions of 59,710 bp and 6,750 bp.
Journal ArticleDOI
Bridging the Rubicon: Phylogenetic analysis reveals repeated colonizations of marine and fresh waters by thalassiosiroid diatoms
TL;DR: This study adds valuable phylogenetic context to previous debate about the nature of the salinity barrier in diatoms and provides compelling evidence that, at least for Thalassiosirales, theSalinity barrier might be less formidable than previously thought.
Journal ArticleDOI
Extensive reorganization of the plastid genome of Trifolium subterraneum (Fabaceae) is associated with numerous repeated sequences and novel DNA insertions.
Zhengqiu Cai,Mary M. Guisinger,Hyi Gyung Kim,Elizabeth C. Ruck,John C. Blazier,Vanity McMurtry,Jennifer V. Kuehl,Jeffrey L. Boore,Robert K. Jansen +8 more
TL;DR: Comparisons of the Trifolium plastid genome with the Plant Repeat Database and searches for flanking inverted repeats suggest that the high incidence of dispersed repeats and rearrangements is not likely the result of transposition.
Journal ArticleDOI
The complete chloroplast genome sequence of Citrus sinensis(L.) Osbeck var 'Ridge Pineapple': organization and phylogenetic relationships to other angiosperms
TL;DR: Phylogenetic analyses resolve relationships among several major clades of angiosperms and provide strong support for the monophyly of the eurosid II clade and the position of the Sapindales sister to the Brassicales/Malvales/Brassicales family.
Journal ArticleDOI
The Complete External Transcribed Spacer of 18S-26S rDNA: Amplification and Phylogenetic Utility at Low Taxonomic Levels in Asteraceae and Closely Allied Families
Craig Randal Linder,Leslie R. Goertzen,Brian D. Vanden Heuvel,Javier Francisco-Ortega,Robert K. Jansen +4 more
TL;DR: It is shown that concerted evolution was proceeding rapidly enough in ETS that species-specific phylogenetic signal was retained and it should be now be possible to use the entire ETS for phylogenetic reconstruction of recently diverged lineages in Asteraceae and at least three other families.
