Ultrastructural changes during the symbiotic seed germination of Gastrodia elata with fungi, with emphasis on the fungal colonization region

Botanical Studies, 2020
Background Gastrodia elata is a fully mycoheterotrophic orchid and has long been used in traditional Chinese medicine. The life cycle of G. elata requires an association with two different fungi-Mycena for seed germination and Armillaria for tuber growth.

Addition of fungal inoculum increases seed germination and protocorm formation in a terrestrial orchid

Global Ecology and Conservation, 2022
Because orchid mycorrhizal fungi are important for orchid seed germination, addition of germination-supporting fungal inoculum to the soil can be an efficient way to improve in situ seed germination of terrestrial orchids, but empirical evidence is still

The worldwide allometric relationship in anatomical structures for plant roots

Plant Diversity, 2023
The cortex (i.e., absorptive tissue) and stele (transportive vascular tissue) are fundamental to the function of plant roots. Unraveling how these anatomical structures are assembled in absorptive roots is essential for our understanding of plant ecology,

The Diverse Assemblage of Fungal Endophytes from Orchids in Madagascar Linked to Abiotic Factors and Seasonality

Diversity, 2021
The inselbergs of the Central Highlands of Madagascar are one of many ‘micro-hotspots’ of biodiversity on the island, particularly for Orchidaceae. In this region are several genera that have a large number of endemic species that are in serious decline ...

Orchid Mycorrhizal Fungi: Identification of Rhizoctonia from West Kalimantan

Microbiology Indonesia, 2016
Orchid is an ornamental plants with high economic value. The excessive exploitation of orchids threatened or even endangered the species, especially those of the epiphytic orchids (Appendiculla sp., Calanthe vestita, and Bulbophyllum beccarii) in West ...

In Vitro Symbiotic Germination: A Revitalized Heuristic Approach for Orchid Species Conservation

Plants, 2020
As one of the largest families of flowering plants, Orchidaceae is well-known for its high diversity and complex life cycles. Interestingly, such exquisite plants originate from minute seeds, going through challenges to germinate and establish in nature.

Morphogenesis Changes in Protocorm Development during Symbiotic Seed Germination of Dendrobium chrysotoxum (Orchidaceae) with Its Mycobiont, Tulasnella sp.

Horticulturae, 2023
The endangered epiphytic orchid, Dendrobium chrysotoxum, is known for its ornamental and medicinal uses. However, knowledge of this orchid’s symbiotic seed germination, protocorm anatomy, and developmental morphology is completely unknown. In this study,

Mixotrophy in orchids: facts, questions, and perspectives. [PDF]

New Phytol
Summary While orchids germinate thanks to carbon from their symbiotic fungi, variable carbon exchanges exist between adult orchids and their mycorrhizal fungi. Although some truly autotrophic orchids reward their fungi with carbon at adulthood, some species remain achlorophyllous and fully dependent on fungal carbon (mycoheterotrophy).

Proteomic and Transcriptomic Analyses Indicate Metabolic Changes and Reduced Defense Responses in Mycorrhizal Roots of Oeceoclades maculata (Orchidaceae) Collected in Nature

Journal of Fungi, 2020
Orchids form endomycorrhizal associations with fungi mainly belonging to basidiomycetes. The molecular events taking place in orchid mycorrhiza are poorly understood, although the cellular changes necessary to accommodate the fungus and to control ...
