Orchidaceae (orchids) is the largest family in the monocots, including about 25,000 species in 880 genera and five subfamilies. Many orchids are highly valued for their beautiful and long-lasting flowers. However, the phylogenetic relationships among the five orchid subfamilies remain unresolved. The major dispute centers on whether the three one-stamened subfamilies, Epidendroideae, Orchidoideae, and Vanilloideae, are monophyletic or paraphyletic. Moreover, structural changes in the plastid…

Plastome Evolution and Phylogeny of Orchidaceae, With 24 New Sequences
Molecular clock analysis based on the whole plastome sequences suggested that Orchidaceae diverged from its sister family 99.2 mya, and the estimated divergence times of five subfamilies are as follows.
Molecular Evolution of Chloroplast Genomes of Orchid Species: Insights into Phylogenetic Relationship and Adaptive Evolution
The phylogenetic analysis based on whole cp genomes showed that C. appendiculata was closely related to C. striata var.
Comparative Analysis of the Complete Plastomes of Apostasia wallichii and Neuwiedia singapureana (Apostasioideae) Reveals Different Evolutionary Dynamics of IR/SSC Boundary among Photosynthetic Orchids
The results revealed that plastid genes exhibited a variable evolution rate within and among different orchid genus, and it was suggested that the plastome-wide evolution of orchid species was disproportional.
The Complete Plastome Sequences of Seven Species in Gentiana sect. Kudoa (Gentianaceae): Insights Into Plastid Gene Loss and Molecular Evolution
The chloroplast (cp) genome is useful in the study of phylogenomics, molecular dating, and molecular evolution. Gentiana sect. Kudoa is a predominantly alpine flowering plant that is valued for its
Plastid phylogenomics of the orchid family: Solving phylogenetic ambiguities within Cymbidieae and Orchidoideae
This study provides an expanded plastid phylogenomic framework of the Orchidaceae and provides new insights on the relationships of one of the most species-rich orchid tribes.
Comparative Plastid Genomics of Neotropical Bulbophyllum (Orchidaceae; Epidendroideae)
The complete plastid genome of eight Bulbophyllum species was sequenced, representing five of six Neotropical taxonomic sections, and selection analyses indicated that protein-coding genes were generally well conserved, but in four genes, there were 95 putative sites under positive selection.
Evolution of plastid genomes of Holcoglossum (Orchidaceae) with recent radiation
Using a comprehensive comparative plastome analysis, it is found that all the indels between different individuals of the same species resulted from the copy number variation of the short repeat sequence, which may be caused by replication slippage.


Comparative Chloroplast Genomes of Photosynthetic Orchids: Insights into Evolution of the Orchidaceae and Development of Molecular Markers for Phylogenetic Applications
The complete chloroplast genomes of the medicinal plant Dendrobium officinale and the ornamental orchid Cypripedium macranthos are reported, demonstrating their gene content and order and potential RNA editing sites, and fifteen highly divergent protein-coding genes were identified, which are useful for phylogenetic analyses in orchids.

The chloroplast genome of Phalaenopsis aphrodite (Orchidaceae): comparative analysis of evolutionary rate with that of grasses and its phylogenetic implications.
It is demonstrated that these conflicting angiosperm phylogenies are most probably linked to the transitional sites at all codon positions, especially at the third one where the strong base-composition bias and saturation effect take place.
Orchid phylogenomics and multiple drivers of their extraordinary diversification
A phylogeny based on 75 chloroplast genes for 39 species representing all orchid subfamilies and 16 of 17 tribes, time-calibrated against 17 angiosperm fossils shows that orchids appear to have undergone one significant acceleration of net species diversification in the orchidoids, and two accelerations and one deceleration in the upper epidendroids.
The plastid genome of the mycoheterotrophic Corallorhiza striata (Orchidaceae) is in the relatively early stages of degradation.
The Corallorhiza plastome is not drastically reduced in overall size, but displays a pattern congruent with a loss of photosynthetic function, which illustrates the urgency of their conservation.
Phylogenetic analysis of 83 plastid genes further resolves the early diversification of eudicots
A phylogenetic hypothesis provides a crucial historical framework for future studies aimed at elucidating the underlying causes of the morphological and species diversity in Pentapetalae.
A phylogenetic analysis of the Orchidaceae: evidence from rbcL nucleotide.
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.
Seven New Complete Plastome Sequences Reveal Rampant Independent Loss of the ndh Gene Family across Orchids and Associated Instability of the Inverted Repeat/Small Single-Copy Region Boundaries
This study sought to resolve deeper-level phylogenetic relationships among major orchid groups and to refine the history of gene loss in the ndh loci across orchids, and suggested that ndhF plays a role in IR/SSC junction stability.
Loss of all plastid ndh genes in Gnetales and conifers: extent and evolutionary significance for the seed plant phylogeny
It is found that all ndh genes are absent across Gnetales and Pinaceae, but not in any other group of gymnosperms, providing additional support for the contentious “gnepine” hypothesis, which places G netales as sister to Pinaceae.
Sequencing and Analysis of Plastid Genome in Mycoheterotrophic Orchid Neottia nidus-avis
The complete sequence of a plastid genome of nonphotosynthetic mycoheterotrophic orchid Neottia nidus-avis is determined using 454 pyrosequencing technology and was found to be reduced in both genome size and gene content; this reduction is however not as drastic as in the other nonphotosynthesis orchid, R. gardneri.
