Friends or relatives? Phylogenetics and species delimitation in the controversial European orchid genus Ophrys.
BACKGROUND AND AIMS Highly variable, yet possibly convergent, morphology and lack of sequence variation have severely hindered production of a robust phylogenetic framework for the genus Ophrys. The aim of this study is to produce this framework as a basis for more rigorous species delimitation and conservation recommendations. METHODS Nuclear and plastid DNA sequencing and amplified fragment...
متن کاملObservations of high genetic variability in the endangered Australian terrestrial orchid Pterostylis gibbosa R. Br. (Orchidaceae).
The genetic variation in all known populations of an endangered Australian native terrestrial orchid Pterostylis gibbosa R.Br., was investigated with starch gel electrophoresis. A total of 16 isozyme loci were assayed. The percentage of polymorphic loci (P), the number of alleles per locus (A), observed and expected heterozygosity at population levels were 69%, 2.21, 0.210, 0.261, respectively....

متن کاملMicrosatellite markers in the western prairie fringed orchid, Platanthera praeclara (Orchidaceae)1
UNLABELLED PREMISE OF THE STUDY Primers for 31 microsatellite-containing loci were developed for the threatened orchid Platanthera praeclara to enable characterization of the population genetics of this tallgrass prairie native. • METHODS AND RESULTS Sixteen polymorphic microsatellite loci were identified from four populations. Six of these loci were not in linkage disequilibrium. The aver...
متن کاملWidespread mycorrhizal specificity correlates to mycorrhizal function in the neotropical, epiphytic orchid Ionopsis utricularioides (Orchidaceae).
Tropical orchids constitute the greater part of orchid diversity, but little is known about their obligate mycorrhizal relationships. The specificity of these interactions and associated fungal distributions could influence orchid distributions and diversity. We investigated the mycorrhizal specificity of the tropical epiphytic orchid Ionopsis utricularioides across an extensive geographical ra...
