Developing a toolbox of Tier I tests to assess pesticides toxicity on the asymbiotic and symbiotic phases of arbuscular mycorrhizal fungi

Ecotoxicology and Environmental Safety
Soil microorganisms are a key protection goal in the European Union (EU) pesticide regulatory framework. Arbuscular mycorrhizal fungi (AMF) were identified as good proxies for assessing pesticides toxicity on the soil microbiota.

Symbiotic vs. asymbiotic seed germination in epiphytic orchids

, 2009
We compared seedling growth of the epiphytic orchid, Tolumnia variegata in agar media with and without inoculated mycorrhizal fungi. Symbiotic germination produced more-developed embryos than asymbiotic germination. Differences were highly significant, although some isolates of Rhizoctonia-like fungi were parasitic on seeds.
