Cleistogamy, a breeding system in which permanently closed, self-pollinated flowers are produced, has received increasing attention in recent years, but the last comprehensive review of this system was over 20 years ago. The goal of this paper is to clarify the different types of cleistogamy, quantify the number of families, genera, and species in which(More)
Studies of mycoheterotrophs, defined as plants that obtain carbon resources from associated mycorrhizal fungi, have fundamentally contributed to our understanding of the importance and complexity of symbiotic ecological interactions. However, to date, the reproductive ecology of these organisms remains empirically understudied, with existing literature(More)
UNLABELLED PREMISE OF THE STUDY Development of genetic markers can be costly and time-consuming, especially when multiple primer pairs are fluorescently labeled. This step was streamlined by combining two techniques in the same PCR reaction: (1) custom-labeling of primers by the investigator and (2) multiplexing multiple primers together in the same(More)
The myco-heterotroph Monotropa hypopitys is a perennial, circumboreally distributed herb of significant importance in studies of nonphotosynthetic plant biology. To address a deficiency in our knowledge of myco-heterotroph population genetics, 11 microsatellite markers were developed using a cost-effective, nonradioactive protocol. Multiplex reactions(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)
PREMISE OF THE STUDY Microsatellite markers were developed for the medicinal plant Isodon rubescens to investigate genetic variability of the species and, in future studies, to assess its relation to the content of pharmacologically active chemicals produced by the plant. METHODS AND RESULTS Eleven primer pairs were identified and tested in multiple(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)
Plant coloration, shown to play a dynamic role in animal attraction, has been proposed as a means of defense, although these reports lack experimental evidence. This study empirically assesses defensive coloration in the mycoheterotrophic plant, Monotropsis odorata, which produces stems and flowers covered by dried vegetative bracts. Field studies were(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)
