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.

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. TheExpand
Phylogeny of sulfate‐reducing bacteria
TLDR
Physiological characteristics particular to each of these groups are discussed, as is the availability of tested group-specific phylogenetic probes and PCR primers directed toward individual groups. Expand
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.

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. Expand
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. Expand
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. Expand
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. Expand
Molecular phylogenetics of Vandeae (Orchidaceae) and the evolution of leaflessness.
TLDR
A change in leaf morphology, monopodial growth habit, and aeration complexes for gas exchange in photosynthetic roots seem to be the most important characters in making the evolutionary transition to leaflessness. Expand
Subtribal and generic relationships of Maxillarieae (Orchidaceae) with emphasis on Stanhopeinae: combined molecular evidence.
The monophyly of and phylogenetic relationships within the orchid tribe Maxillarieae Pfitzer were evaluated using parsimony analyses of combined nuclear ribosomal and plastid DNA sequence data of ITSExpand
