Commodity risk assessment of Alnus cordata, Alnus glutinosa and Alnus incana plants from the UK

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘high‐risk plants, plant products and other objects’. Taking into account the available scientific information, including the technical information provided by ...

Identification of fungal associates of the swamp helmet orchid (Corybas carsei), a threatened (nationally critical) species

New Zealand Journal of Botany, Volume 62, Issue 4, Page 595-608, December 2024.
ABSTRACT Corybas carsei is one of New Zealand's most endangered orchids, with a single remaining population in the Whangamarino Wetland (North Island). Although orchid mycorrhizae have proved a critical aspect of orchid conservation globally, until now mycorrhizal fungi of C. carsei have not been identified or utilised for conservation.

Viroid and viroid‐like elements in plants and plant‐associated microbiota: a new layer of biodiversity for plant holobionts

New Phytologist, Volume 244, Issue 4, Page 1216-1222, November 2024.
Summary The functional relevance of plant‐associated microorganisms is theoretically framed within the holobiont concept. The role of viruses in plant holobionts is being recognized both for their direct effects when hosted in plants (cryptic plant viruses) and for their indirect effects when infecting microorganisms associated with plants in ...

Convergent losses of decay mechanisms and rapid turnover of symbiosis genes in mycorrhizal mutualists. [PDF]

, 2015
To elucidate the genetic bases of mycorrhizal lifestyle evolution, we sequenced new fungal genomes, including 13 ectomycorrhizal (ECM), orchid (ORM) and ericoid (ERM) species, and five saprotrophs, which we analyzed along with other fungal genomes ...

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia

Ecology and Evolution, Volume 14, Issue 10, October 2024.
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

Mycorrhizal Compatibility and Germination-Promoting Activity of Tulasnella Species in Two Species of Orchid (Cymbidium mannii and Epidendrum radicans)

Horticulturae, 2021
In nature, Orchidaceae seeds establish a relationship with orchid mycorrhizal fungi to obtain essential nutrients for germination. The orchids, Cymbidium mannii and Epidendrum radicans, have significant ornamental and economic value.

Fungal and plant gene expression in the Tulasnella calospora - Serapias vomeracea symbiosis provides clues on N pathways in orchid mycorrhizas [PDF]

New Phytologist, 2017
Summary Orchids are highly dependent on their mycorrhizal fungal partners for nutrient supply, especially during early developmental stages. In addition to organic carbon, nitrogen (N) is probably a major nutrient transferred to the plant because orchid tissues are highly N‐enriched.

Photosynthate transfer from an autotrophic orchid to conspecific heterotrophic protocorms through a common mycorrhizal network

New Phytologist, Volume 243, Issue 1, Page 398-406, July 2024.
Summary The minute ‘dust seeds’ of some terrestrial orchids preferentially germinate and develop as mycoheterotrophic protocorms near conspecific adult plants. Here we test the hypothesis that mycorrhizal mycelial connections provide a direct pathway for transfer of recent photosynthate from conspecific green orchids to achlorophyllous protocorms ...
