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.
Phylogeny of the eudicots : a nearly complete familial analysis based on rbcL gene sequences
TLDR
A phylogenetic analysis of 589 plastid rbcL gene sequences representing nearly all eudicot families was performed, and bootstrap re-sampling was used to assess support for clades.
Orchid phylogenomics and multiple drivers of their extraordinary diversification
TLDR
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.
Evolution along the crassulacean acid metabolism continuum
TLDR
This review focuses on five main topics: (1) the permutations and plasticity of CAM, (2) the requirements for CAM evolution, (3) the drivers of CAM evolution; (4) the prevalence and taxonomic distribution of CAM among vascular plants with emphasis on Orchidaceae; and (5)themolecular underpinning sofCAMevolution includingcircadianclockregulation of gene expression.
ORCHID FLORAL FRAGRANCES AND MALE EUGLOSSINE BEES: METHODS AND ADVANCES IN THE LAST SESQUIDECADE
All species of the Neotropical subtribes Stanhopeinae and Catasetinae (Orchi daceae) are pollinated exclusively by male euglossine bees which are attracted to and collect the floral fragrances. The
Generic recircumscriptions of Oncidiinae (Orchidaceae: Cymbidieae) based on maximum likelihood analysis of combined DNA datasets
TLDR
A classification based on monophyly will facilitate focused monographs and clarifies the evolution of morphological and biochemical traits of interest within this highly diverse subtribe.
Floral convergence in Oncidiinae (Cymbidieae; Orchidaceae): an expanded concept of Gomesa and a new genus Nohawilliamsia.
TLDR
Convergence on a stereotypical syndrome of floral traits associated with pollination by oil-collecting bees has resulted in these characters not being reliable for producing monophyletic taxa, and the genus Oncidium, defined by these characters, is grossly polyphyletic.
Molecular phylogenetics of Maxillaria and related genera (Orchidaceae: Cymbidieae) based on combined molecular data sets.
TLDR
The results support the recognition of a more restricted Maxillaria, of some previously published segregate genera (Brasiliorchis, Camaridium, Christensonella, Heterotaxis, Ornithidium, Sauvetrea), and of several novel clades at the generic level.
Fragrance Collection, Storage, and Accumulation by Individual Male Orchid Bees
TLDR
GC-MS analyses of 153 males of three species showed that individual hind tibiae contain highly variable quantities of a complex and species-specific blend of fragrance compounds, mainly terpenoids and aromatics.
Generic realignments in Maxillariinae (Orchidaceae)
TLDR
A new phylogenetic classification for core Maxillariinae that recognizes 17 genera is presented and some new synonyms at the specific level are also presented.
