Mycorrhizal diversity in photosynthetic terrestrial orchids
• Specific orchid–fungal associations are known for nonphotosynthetic orchids but fungal diversity in photosynthetic orchids is thought to be quite broad. Specific fungal associations will figure prominently in conservation efforts, while diverse associations may require less attention. We combined culture techniques with ITS and mtLSU sequences and phylogenetic analysis to determine the geneti...
متن کاملHigh specificity generally characterizes mycorrhizal association in rare lady's slipper orchids, genus Cypripedium.
Lady's slipper orchids (Cypripedium spp.) are rare terrestrial plants that grow throughout the temperate Northern Hemisphere. Like all orchids, they require mycorrhizal fungi for germination and seedling nutrition. The nutritional relationships of adult Cypripedium mycorrhizae are unclear; however, Cypripedium distribution may be limited by mycorrhizal specificity, whether this specificity occu...

متن کاملIntroduction: Biology of orchids and of orchid mycorrhizal interactions
With the nursery and garden center industry expanding, it is important to keep the consumer returning year after year for the newest, most exciting and most unusual species. Perennial nursery crops are one sector of the nursery market that has grown rapidly due to the addition of new species. Though orchids are not new to the horticultural trade, these fascinating plants have long been in the d...
متن کاملMycorrhizal Associations and Trophic Modes in Coexisting Orchids: An Ecological Continuum between Auto- and Mixotrophy
Two distinct nutritional syndromes have been described in temperate green orchids. Most orchids form mycorrhizas with rhizoctonia fungi and are considered autotrophic. Some orchids, however, associate with fungi that simultaneously form ectomycorrhizas with surrounding trees and derive their carbon from these fungi. This evolutionarily derived condition has been called mixotrophy or partial myc...
