Essay on Mycorrhizae - 627 Words.

An arbuscular mycorrhiza (plural mycorrhizas, a.k.a. endomycorrhiza) is a type of mycorrhiza in which the symbiont fungus (AM fungi, or AMF) penetrates the cortical cells of the roots of a vascular plant forming arbuscules. (Not to be confused with ectomycorrhiza or ericoid mycorrhiza.).

Arbuscular mycorrhizae are symbiotic relationships between specialized soil fungi and plant roots. The relationship between the plants and the fungi benefit the fungi and the plants by raising the quality of the soil and providing more access to available nutrients to each.

Arbuscular mycorrhizal fungi (AMF) are beneficial soil microorganisms establishing mutualistic symbioses with the roots of the most important food crops and playing key roles in the maintenance of long-term soil fertility and health. The great inter- and intra-specific AMF diversity can be fully exploited by selecting AMF inocula on the basis of their colonization ability and efficiency, which.

Arbuscular mycorrhizal fungi are soilborne microorganisms that form a mutualistic symbiotic association with most land plants. As obligate biotrophs these fungi are unable to complete their life cycle in the absence of the host plant.

As important components of the photosynthetic apparatus, photosystems I (PS I) and II (PS II) are sensitive to salinity. Salt stress can destroy the PS II reaction center, disrupt electron transport from PS II to PS I, and ultimately lead to a decrease in the photosynthetic capacity of the plant. Arbuscular mycorrhizal fungi (AMF) can enhance the photosynthetic capacity of a host plant under.

Arbuscular mycorrhizal fungi (AMF) are grouped in a monophyletic group, the phylum Glomeromycota. In this review, the history and complexity of the taxonomy and systematics of these obligate biotrophs is addressed by recognizing four periods.

Arbuscular (AM) endomycorrhizas are the most common type of mycorrhizal association, and were probably the first to evolve; the fungi are members of the Glomeromycota. In other textbooks you may find these fungi placed in the Order Glomales and Phylum Zygomycota but this is incorrect. The AM fungi are obligate biotrophs, and they are associated with roots of about 80% of plant species (that.

Arbuscular mycorrhizal communities are usually characterized by their spores but, since spores can rarely be directly associated with individual plants or plant species, a more satisfactory approach would be to identify fungal symbionts where they interact with the host plant, in the roots.

Mycorrhizal types Mycorrhizas were traditionally classified into the two types: ectotrophic and endotrophic, a classification based on the location of the fungal hyphae in relation to the root tissues of the plant; ecto means outside the root, endo means inside.

Arbuscular mycorrhizal fungus forms mutually beneficial associations between species in the fungal subphylum Glomeromycotina (Spatafora et al., 2016; Davison et al., 2018) and the roots of 80% of vascular plants (Smith and Read, 2008).

The widespread symbiotic interaction between plants and arbuscular mycorrhizal (AM) fungi relies on a complex molecular dialog with reciprocal benefits in terms of nutrition, growth, and protection. Approximately 29% of all vascular plant species do not host AM symbiosis, including major crops. Under certain conditions, however, presumed non-host plants can become colonized by AM fungi and.
