Several unrelated subshrub species also converge either by an ericoid
habit, by leaves congested at the branch apices, and by decussate phyllotaxis.
Ectomycorrhizal and ericoid
mycorrhizal fungi can produce extracellular enzymes that decompose components of each of the major classes of organic compounds commonly found in soils (Table 1).
Only one species is recorded from the Sambirano Rainforest and none from the Montane Ericoid
Mechanism of arsenate resistance in the Ericoid
mycorrhizal fungus Hymenoscyphus ericae.
Influence of zinc ions on protein secretion in a heavy metal tolerant strain of the ericoid
mycorrhizal fungus Oidiodendron mains.
In addition to arbuscular mycorrhizal (AM) fungi, which will be discussed in greater detail, ericoid
mycorrhizal fungi colonize the root cells of their host, producing an infection unit that involves a single host cell without spreading to the neighboring root cells.
15]N abundance of subarctic plants provide field evidence that ericoid
, ectomycorrhizal and non- and arbuscular mycorrhizal species access different sources of soil nitrogen.
In the Peruvian-Chilean Andes, the puna consists of a lower layer of shrub vegetation, tolar, dominated by tola (Lepidophyllum quadrangulare) and several ericoid
species of Parastrephia (Asteraceae), and an upper layer, the pajonal, occupied by open herbaceous communities with ichu (Stipa ichu, and other grasses, mainly of the genera Stipa and Calamagrostis) and the fescue paja brava (Festuca orthophylla) with patches of bofedales (see photo 146, page 241).
2003) documented that ericoid
mycorhizal fungi secreted organic acid to solubilize Zn from insoluble ZnO and Zn3 (PO4)2.
