Scientific interest in orchid mycorrhizas, the symbiotic association between orchid roots and
fungi, continues to grow. Advances in molecular identification techniques have enabled the …

This chapter reviews the discovery of mixotrophy in mycorrhizal plants, the available data on
mixotrophic physiology, and the evolutionary link between mixotrophy and full …

The purpose of this chapter is to provide a practical and theoretical framework for the study
of the ecophysiology of mycoheterotrophic plants. We accomplish this by providing a …

• Premise of the study: Both abiotic and biotic factors shape species distributions. Orchids
produce minute seeds with few nutrient reserves, thus requiring mycorrhizal fungi for …

Background Mycoheterotrophic plants are considered to associate very specifically with
fungi. Mycoheterotrophic orchids are mostly associated with ectomycorrhizal fungi in …

Perhaps with the exception of a small number of cultivated saprobic species, the true truffles
(Tuber spp.) command the attention of more scientists than other species of mushroom …

Two distinct nutritional syndromes have been described in temperate green orchids. Most
orchids form mycorrhizas with rhizoctonia fungi and are considered autotrophic. Some …

Abstract Background and Aims In orchid species that have populations occurring in strongly
contrasting habitats, mycorrhizal divergence and other habitat-specific adaptations may lead …

What factors determine the distribution of a species is a central question in ecology and
conservation biology. In general, the distribution of plant species is assumed to be controlled …

Abstract Background and Aims Partially mycoheterotrophic plants are enriched in 13C and
15N compared to autotrophic plants. Here, it is hypothesized that the type of mycorrhizal …
