Résumé :

This review examines the results of scientific experiments of foreign and domestic researchers in the field of studying mycorrhizal associations, the mechanisms of their symbiosis with plants. The information about the current state of the issue is given: different points of view on the interaction of mycorrhizal plants with mycobionts. A comparative analysis of the development of mycorrhiza in individual plant species was carried out. It was found that the maximum degree of mycorrhiza development corresponds to the beech and linden families. The factors influencing the development of balanced

Résumé :

An estimate was made of the abundance of different types of mycorrhizal associations in two plant communities of conifers and hardwoods in the Harvard Forest. Lists of plant species, the coverage of their foliage in the canopy and understorey layers, and the types of mycorrhizal associations for 45 species common in these communities are presented. Of the species examined, 91 % were mycorrhizal, representing most of the known major types, viz. ectomycorrhiza, vesicular–arbuscular mycorrhiza (VAM), ericoid, and monotropoid mycorrhiza. Of the 45 species studied, 22% of the species showed ectomyc

Résumé :

The majority of vascular flowering plants are able to form symbiotic associations with arbuscular mycorrhizal fungi. These symbioses, termed arbuscular mycorrhizas, are mutually beneficial, and the fungus delivers phosphate to the plant while receiving carbon. In these symbioses, phosphate uptake by the arbuscular mycorrhizal fungus is the first step in the process of phosphate transport to the plant. Previously, we cloned a phosphate transporter gene involved in this process. Here, we analyze the expression and regulation of a phosphate transporter gene (GiPT) in the extra-radical mycelium of

Résumé :

The roots of the plants are in contact with a substrate, and biotic and abiotic factors influence their functioning and development. The most known microorganisms associated with plant roots are soil fungi, which are adapted to the soil's living environment, called mycorrhizae. Arbuscular mycorrhizae are the most common of these associations. In agricultural ecosystems, the constant use of technologies has resulted in a progressive reduction of mycorrhizal diversity. Due to this phenomenon, soil presents a lower potential for the development of multi-level hyphal networks which implies reduced

Résumé :

Arbuscular mycorrhizas represent the most widespread, and probably most ancient, type of plant–fungus association in which the large majority of terrestrial plants must have evolved with compatibility systems towards the fungal symbionts. Cellular interactions leading to reciprocal morphofunctional integration between symbionts during mycorrhiza establishment are complex. Some plant genes and cellular events may be shared with nodulation processes, but there is evidence of molecular modifications specific to arbuscular mycorrhiza formation.

The cytoplasmic volume of the mycorrhizal cells is not significantly increased. With Terfezia leptoderma an ectomycorrhiza without a sheath is formed, but there is a typical Hartig net. These two types of mycorrhiza constitute examples of biotrophism.

Abstract Mycorrhiza refers to a mutualistic, symbiotic relationship formed between fungi (Gr. mukes) and living roots (Gr. rhiza) of higher plants. These associations are prevalent among most plant species and have been observed in most vegetables except the Cruciferae and Chenopodiaceae. In fact, some vegetables do not appear to grow or develop normally without mycorrhizae. In addition to their wide distribution in the plant kingdom, these nonpathogenic relationships are geographically ubiquitous. Thus, the mycorrhizal condition is the rule, as both host plant and fungus specificity is minima

Arbuscular mycorrhizas (AM) are symbiotic associations formed by fungi from the Glomeromycota and most angiosperms. Despite the widespread occurrence of the association, its ecological significance, and its potential importance in agriculture, relatively little is known at the molecular level about the development, functioning, and regulation of the symbiosis. We have selected Medicago truncatula Gaertn. 'Jemalong' and an AM fungus, Glomus versiforme (Karsten) Berch, for molecular genetic analyses of the AM symbiosis. Here we used macroarrays as a screening tool to enable the rapid identificat

Résumé :

Arbuscular mycorrhizas are widespread in land plants including liverworts, some of the closest living relatives of the first plants to colonize land 500 million years ago (MYA). Previous investigations reported near-exclusive colonization of liverworts by the most recently evolved arbuscular mycorrhizal fungi, the Glomeraceae, indicating a recent acquisition from flowering plants at odds with the widely held notion that arbuscular mycorrhizal-like associations in liverworts represent the ancestral symbiotic condition in land plants.

Résumé :

Over 85% of land plants engage in symbiotic relationships with mycorrhiza-forming soil fungi that colonise their roots. These mycorrhizal symbioses, which involve the exchange of fungal-acquired nutrients and water for photosynthetically fixed plant carbon, are considered a promising nature-based solution to making agricultural practices more sustainable. In order to implement the widespread use of mycorrhizal fungi in agriculture, a more complete awareness of mycorrhizal fungal diversity and range of plant hosts is needed.

The mycorrhizal associations of plant species in an open woodland and heathland on Hawkesbury Sandstone soils were examined. The two geographically disjunct sites supported vegetation of differing physiognomy, but possessed many species common to both sites. At the woodland site, 21 of the 32 plant species examined had mycorrhizal associations. At the heath site, 31 of the 47 plant species examined were mycorrhizal. Mycorrhizal associations were found on representatives of the Cyperaceae and Proteaceae, families not previously thought to be mycorrhizal. Internal hyphae, vesicles, and cortical

Résumé :

Ectomycorrhizal (EcM) and arbuscular mycorrhizal (AM) associations of Salix repens were studied at 16 sites in different successional stages of dune ecosystems (calcareous-acidic, dry-wet) in the Netherlands. High EcM colonization, low AM colonization, and lack of differences between habitats indicate that ectomycorrhizas do not increase their importance in later successional stages. EcM and AM colonization and plant-nutrient status indicate that the relative importance of P and N does not change during succession, but during seasons. Salix repens showed low levels of AM colonization but, neve

Résumé :

Mycorrhizal fungi provide plants with a range of benefits, including mineral nutrients and protection from stress and pathogens. Here we synthesize current information about how the presence and type of mycorrhizal association affect plant communities. We argue that mycorrhizal fungi regulate seedling establishment and species coexistence through stabilizing and equalizing mechanisms such as soil nutrient partitioning, feedback to soil antagonists, differential mycorrhizal benefits, and nutrient trade. Mycorrhizal fungi have strong effects on plant population and community biology, with mycorr

Résumé :

Mycorrhizas play an important role in plant growth and development. In mycorrhizal symbioses, fungi supply soil mineral nutrients, such as nitrogen and phosphorus, to their host plants in exchange for carbon resources. Plants gain as much as 80% of mineral nutrient requirements from mycorrhizal fungi, which form associations with the roots of over 90% of all plant species. Orchid seeds lack endosperms and contain very limited storage reserves. Therefore, the symbiosis with mycorrhizal fungi that form endomycorrhizas is essential for orchid seed germination and protocorm development under natur

Résumé :

Ericoid mycorrhiza (ErM) is an unexplored and understudied member of the mycorrhizal world, surprisingly belonging to Ascomycota and Basidiomycota instead of Glomeromycota (the phylum comprising fungi forming associations with higher plants). ErM obtained its etymology due to its symbiotic relationship with members of the Ericaceae Family. Just like any other mycorrhiza, ErM also helps its hosts through nitrogen uptake and phosphorus bioavailability and provides defense to host plants against various phytopathogens. It also takes part in the decomposition of organic matter and depolymerization

Plants require adequate P from the very early stages of growth for optimum crop production. Phosphorus supply to the crop is affected by soil P, P fertilizer management and by soil and environmental conditions influencing P phytoavailability and root growth. Phosphorus uptake in many crops is improved by associations with arbuscular mycorrhizal fungi. Cropping system and long-term input of P through fertilizers and manures can influence the amount and phytoavailability of P in the system and the development of mycorrhizal associations.
