Abstract: Publisher Summary This chapter discusses the ecological implications of mycorrhizal associations in natural ecosystems and the role of soil or environmental factors, mycorrhizal fungus characteristics or host plant properties. Mycorrhizal associations are regulated by features of the host plant and mycorrhizal fungus, as well as by soil conditions and environmental factors. Factors which can influence the occurrence and effectiveness of mycorrhizal associations include (1) root properties (2) edaphic or climatic factors (3) soil organisms, (4) soil disturbance, and (5) host-fungus compatibility. Several other complex ecological topics also discussed in the chapter include (1) mycorrhizal phenology , (2) factors responsible for varying degrees of mycorrhizal dependency in host plants, (3) the role of mycorrhizal hyphae in soil (4) nutrient competition involving mycorrhizal and non-mycorrhizal plants, and (5) mycorrhizal interactions involving pollution and other stresses, the rhizosphere, soil properties and allelopathy. Finally, the chapter also discusses the population ecology of mycorrhizal fungi and the influence of their associations on plant population ecology.

Agricultural uses of plant biostimulants
TL;DR: There is growing scientific evidence supporting the use of biostimulants as agricultural inputs on diverse plant species, such as increased root growth, enhanced nutrient uptake, and stress tolerance.
Coevolution of roots and mycorrhizas of land plants
TL;DR: It is hypothesised that roots gradually evolved from rhizomes to provide more suitable habitats for mycorrhizal fungi and provide plants with complex branching and leaves with water and nutrients.

Mycorrhizal associations and other means of nutrition of vascular plants: understanding the global diversity of host plants by resolving conflicting information and developing reliable means of diagnosis
TL;DR: A case study of Western Australian plants revealed that plants with specialised nutritional modes such as carnivory, cluster roots, or EM were much more diverse in this ancient landscape with infertile soils than elsewhere.

Incorporating the soil community into plant population dynamics: the utility of the feedback approach.
TL;DR: Using a simple experimental protocol, substantial negative feedback on plant growth is found through the soil community, suggesting that it may be involved in the maintenance of plant species diversity.

Arbuscular mycorrhizal fungi in alleviation of salt stress: a review.
TL;DR: This review gives useful benchmark information for the development and prioritization of future research programmes and identifies certain lesser explored areas such as molecular and ultra-structural changes where further research is needed for better understanding of symbiosis with reference to salt stress.

Allelopathic effects of litter on the growth and colonization of mycorrhizal fungi.
TL;DR: Allelochemicals in the litter may inhibit seedling growth and suppress fungai growth and root colonization in the field, thus explaining the failures of reforestation by conifer species in disturbed sites.

The development of vesicular-arbuscular mycorrhizal infection in plant root systems
F. E. Sanders,N. A. Sheikh +1 more
TL;DR: Many crop plants carry VA mycorrhizal infection, which benefits their host principally by increasing the rate of phosphorus uptake from soils low in available phosphorus.

Va mycorrhizae in strand vegetation of hawaii: evidence for long-distance codispersal of plants and fungi
R. E. Koske,J. N. Gemma +1 more
TL;DR: The close association between propagules of VAMF and vegetative fragments of indigenous plants found in the present study suggests a mechanism of codispersal that appears to ensure the maintenance of the symbiosis in nutrient-deficient sites where it is most beneficial.
