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.

Strong emission of methyl chloride from tropical plants
TLDR
Observations of large emissions of methyl chloride from some common tropical plants (certain types of ferns and Dipterocarpaceae), ranging from 0.1 to 3.7 µg per gram of dry leaf per hour, indicate a substantial shortfall in the overall methyl chloride budget.

Evidence for novel and specialized mycorrhizal parasitism: the orchid Gastrodia confusa gains carbon from saprotrophic Mycena
TLDR
The results demonstrate for the first time using molecular and mass-spectrometric approaches that myco-heterotrophic plants gain carbon through parasitism of wood or litter decaying fungi.

THE EVOLUTIONARY HISTORY OF MYCORRHIZAL SPECIFICITY AMONG LADY'S SLIPPER ORCHIDS
TLDR
Mycorrhizal specificity in genus Cypripedium appears to be an evolvable trait, and associations with particular fungi are phylogenetically conserved.

Molecular phylogenetics of subtribe Aeridinae (Orchidaceae): insights from plastid matK and nuclear ribosomal ITS sequences
TLDR
It was found that the inconsistencies are mainly caused by homoplasy of these characters, and monophyly of subtribe Aeridinae was tentatively supported in which 14 subclades reflecting phylogenetic relationships can be recognized.

Germination of mature seeds of Calanthe tricarinata Lindl., an endangered terrestrial orchid, by asymbiotic culture in vitro
TLDR
The protocorms obtained in this study were developed to plantlets readily after transferring to fresh 1/2 MS medium without any plant growth regulators, and the significant role of a reproducible protocol for the germination of mature seeds is discussed in terms of the ex situ conservation of endangered orchid species.

Phylogenetic analysis of Petunia sensu Jussieu (Solanaceae) using chloroplast DNA RFLP.
TLDR
Several clades found in the phylogenetic trees corresponded to their distribution ranges, suggesting that recent speciation in the genus Petunia sensu Jussieu occurred independently in several different regions.

Mycorrhizal diversity in Apostasia (Orchidaceae) indicates the origin and evolution of orchid mycorrhiza.
We demonstrated that "orchid mycorrhiza," a specialized mycorrhizal type, appeared in the common ancestor of the largest plant family Orchidaceae and that the fungal partner shifted from…

Epipactis helleborine shows strong mycorrhizal preference towards ectomycorrhizal fungi with contrasting geographic distributions in Japan
TLDR
It is indicated that mycorrhizal association with geographically restricted pezizalean ectomycorrhIZal fungi is a key control upon this orchid species’ distribution across widely different forest habitats.

Phylogenetic relationships of Clematis (Ranunculaceae) based on chloroplast and nuclear DNA sequences
TLDR
Enormous morphological diversification and very few nucleotide substitutions within Clematis indicate the recent radiation of the genus.
