Pterospora andromedea, a mycoheterotroph, has been shown to form obligate symbioses with only three species of Rhizopogon in section Amylopogon: R. salebrosus, R. arctostaphyli and an undescribed molecular taxon. Sarcodes sanguinea, another my coheterotroph in Ericaceae, and sister taxon to Pterospora andromedea, has been found to form symbioses with two(More)
UNLABELLED PREMISE OF THE STUDY Rhizopogon kretzerae and R. salebrosus (Rhizopogonaceae) are ectomycorrhizal fungi symbiotic with pines and the mycoheterotrophic plant Pterospora andromedea (Ericaceae). Microsatellite loci will allow population genetic study of fungal hosts to P. andromedea. • METHODS AND RESULTS Shotgun pyrosequencing of R. kretzerae(More)
UNLABELLED PREMISE OF THE STUDY Pterospora andromedea (Ericaceae) is a mycoheterotrophic plant endemic to North America with a disjunct distribution. Eastern populations are in decline compared to western populations. Microsatellite loci will allow comparison of genetic diversity in endangered to nonthreatened populations. • METHODS AND RESULTS(More)
Rhizopogon species are ecologically significant ectomycorrhizal fungi in conifer ecosystems. The importance of this system merits the development and utilization of a more robust set of molecular markers specifically designed to evaluate their evolutionary ecology. Anonymous nuclear loci (ANL) were developed for R. subgenus Amylopogon. Members of this(More)
The mycoheterotrophic plant Pterospora andromedea is an important species in understanding the evolution and ecology of highly specialized plant-fungal symbioses. Lineages within P. andromedea have been shown to engage in highly specific interactions with obligate fungal associates found in Rhizopogon subgenus Amylopogon. Unfortunately, evidence of highly(More)
