Comparison of green and albino individuals of the partially mycoheterotrophic orchid Epipactis helleborine on molecular identities of mycorrhizal fungi, nutritional modes and gene expression in
Gene expression analyses showed that genes involved in antioxidant metabolism were upregulated in the albino variants, which indicates that these plants experience greater oxidative stress than the green variants, possibly due to a more frequent lysis of intracellular pelotons.
Gastrodia takeshimensis (Orchidaceae), a New Mycoheterotrophic Species from Japan
A new species, Gastrodia takeshimensis Suetsugu from Takeshima Island, Kagoshima Prefecture, Japan, is described and illustrated and its elongated corolla tube suggests a close affinity to G. nipponica.
Host range and selectivity of the hemiparasitic plant Thesium chinense (Santalaceae).
This is the first quantitative investigation of the host range and selectivity of hemiparasitic plants of the Santalales and indicates that Thesium chinense generally preferred the Poaceae, although haustoria formed on the Fabaceae were larger than those on other hosts.

A comparative investigation into the breeding system of two fully mycoheterotrophic orchids, Cymbidium macrorhizon and C. lancifolium, finds autogamy would likely be favoured as a reproductive assurance to compensate for pollinator limitation due to their lack of nectar and pollinators’ hostile habitat preferences.
Partial mycoheterotrophy in the leafless orchid Cymbidium macrorhizon.
The results indicated that despite its leafless status, fruiting plants of C. macrorhizon were capable of fixing significant quantities of carbon, and should be considered a partially mycoheterotrophic species rather than fully myco heterotrophic, at least during the fruiting stage.
Effects of the hemiparasitic plant Pedicularis kansuensis on plant community structure in a degraded grassland
Host associations of P. kansuensis are examined and it is suggested that the plant modifies the competitive balance in grassland communities of the Qinghai-Tibet Plateau, allowing for colonization by subordinate species and thereby enhancing species diversity and contributing to restoration of these degraded grasslands.
The tiny-leaved orchid Cephalanthera subaphylla obtains most of its carbon via mycoheterotrophy
During the evolutionary pathway to full mycoheterotrophy, some plant species appear to have gained strong my coheterotrophic abilities before completely losing foliage leaves.
Gastrodia flexistyloides (Orchidaceae), a new mycoheterotrophic plant with complete cleistogamy from Japan
A new species, Gastrodia flexistyloides (Orchidaceae: Epidendroideae, Gastrodieae) from Takeshima Island, Kagoshima Prefecture, Japan, is described and illustrated. In its trilobed column with a
Avian seed dispersal in a mycoheterotrophic orchid Cyrtosia septentrionalis
Avian seed dispersal in a mycoheterotrophic orchid Cyrtosia septentrionalis, which occurs under closed canopies where wind is less dependable, is reported.
Independent recruitment of a novel seed dispersal system by camel crickets in achlorophyllous plants.
Investigation of the seed dispersal system in three unrelated fully heterotrophic plants with fleshy, indehiscent fruits revealed that camel crickets are the major seed disperser in three achlorophyllous plants in the study population.
