As characteristic of all orchids, " Epipactis " spp . are dependent on a mycorrhizal symbiosis ( see also Orchid mycorrhiza ).
32.
The mycorrhiza had penetrated the rock by excreting acids, allowing plant roots to reach almost 2 meters into the rocky soil and reach groundwater.
33.
The difference to ectomycorrhiza is that some hyphae actually penetrate into the root cells, making this type of mycorrhiza an " ectendomycorrhiza ".
34.
The main donors to the pathway were the genes associated with the arbuscular mycorrhiza symbiosis genes, the pollen tube formation genes and the haemoglobin genes.
35.
The "'ericoid mycorrhiza "'is a mutualistic symbiosis formed between members of the plant family Ericaceae and several lineages of fungi.
36.
The plants provide habitat and food for insects ( including Lepidoptera ), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza.
37.
Some of these bacteria, known as Mycorrhiza Helper Bacteria ( MHBs ), have been shown to stimulate EcM formation, root and shoot biomass.
38.
Russulaceae fruitbodies are subject to monotropoids, also parasitise ectomycorrhizal Russulaceae and their plant partners see above, " Other types of mycorrhiza ".
39.
Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their cortical root cells, known as the Hartig net.
