A phylogenetic analysis of the Orchidaceae: evidence from rbcL nucleotide.
TLDR
RbcL fails to provide strong support for the interrelationships of the subfamilies of the Orchidaceae, and the cladograms presented here should serve as a standard to which future morphological and molecular studies can be compared.
An expanded plastid DNA phylogeny of Orchidaceae and analysis of jackknife branch support strategy.
TLDR
It is found that support values plateau rapidly with increased search effort, and tree bisection-reconnection swapping in a single search replicate per jackknife replicate and saving only two trees resulted in values that were close to those obtained in the most extensive searches.
Molecular phylogenetics of Diseae (Orchidaceae): a contribution from nuclear ribosomal ITS sequences.
TLDR
The first molecular phylogeny of tribe Diseae (Orchidoideae: Orchidaceae) is presented, with Morphological characters fully congruent with the well-supported groups identified in the ITS phylogeny.
A phylogenetic analysis of Diurideae (Orchidaceae) based on plastid DNA sequence data.
DNA sequence data from plastid matK and trnL-F regions were used in phylogenetic analyses of Diurideae, which indicate that Diurideae are not monophyletic as currently delimited. However, if…
Phylogenetic Relationships of Monocots Based on the Highly Informative Plastid Gene ndhF
TLDR
The resulting tree is highly resolved and places commelinids sister to Asparagales, with both sister to Liliales-Pandanales in the strict consensus; Pandanales are sister to Dioscoreale in the bootstrap majority-rule tree, just above Petrosaviales.
Molecular systematics and biogeography of the amphibious genus Littorella (Plantaginaceae).
TLDR
Comparing the phylogeny proposed by Rahn to one based on DNA sequence data from the internal transcribed spacer (ITS) region indicates that Littorella forms a strongly supported monophyletic clade sister to Plantago and its recognition at the generic rank appears warranted.
Polyphyly of mycoheterotrophic orchids and functional influences on floral and molecular characters
Character analysis of the seed coat in Spiranthoideae and Orchidoideae, with special reference to the Diurideae (Orchidaceae)
TLDR
Using quantitative descriptors of size and shape, it is demonstrated that some of the existing seed classes do not represent well delimited, discrete entities, and proposed new seed classes to meet these criteria are proposed.
Repeated evolution of net venation and fleshy fruits among monocots in shaded habitats confirms a priori predictions: evidence from an ndhF phylogeny
We present a well-resolved, highly inclusive phylogeny for monocots, based on ndhF sequence variation, and use it to test a priori hypotheses that net venation and vertebrate-dispersed fleshy fruits…
Phylogenetics of Arethuseae (Orchidaceae) Based on Plastid matK and rbcL Sequences
TLDR
Assessment of Sequences of two plastid genes for Arethuseae sensu Dressler and component subtribes indicate that the tribe may not be monophyletic and that this gene may be non-functional within Orchidaceae.
