TLDR
The factors responsible for establishment of the beneficial soil fungi, arbuscular mycorrhizal fungi (AMF), which can enhance the yield of a wide range of agricultural crops are explored.Abstract:
Soil biota provide a number of key ecological services to natural and agricultural ecosystems. Increasingly, inoculation of soils with beneficial soil biota is being considered as a tool to enhance plant productivity and sustainability of agricultural ecosystems. However, one important bottleneck is the establishment of viable microbial populations that can persist over multiple seasons. Here, we explore the factors responsible for establishment of the beneficial soil fungi, arbuscular mycorrhizal fungi (AMF), which can enhance the yield of a wide range of agricultural crops. We evaluate field application potential and discuss ecological and evolutionary factors responsible for application success. We identify three factors that determine inoculation success and AM fungal persistence in soils: species compatibility (can the introduced species thrive under the imposed circumstances?); field carrying capacity (the habitat niche available to AMF); and priority effects (the influence of timing and competition on the establishment of alternative stable communities). We explore how these factors can be employed for establishment and persistence of AMF. We address the importance of inoculum choice, plant choice, management practices and timing of inoculation for the successful manipulation of the resulting AMF community.read more

TL;DR: In this article, it is shown that if it is to be sustainable, agriculture will depend on increased nutrient flux through AM networks as the global population heads toward 9 billion in coming years.

Interaction of arbuscular mycorrhizal inoculants and chicken manure in avocado rootstock production
TL;DR: Overall, responses to mycorrhizal inoculation were minor and increasing fertilization negatively affected most variables, and the best inocula were the Cetraspora pellucida and native orchard mycor rhizal community inocula.

Activation of the Jasmonate Biosynthesis Pathway in Roots in Drought Stress
TL;DR: New insights are reported on the role of the activation of Jasmonic Acid bios ynthesis during abiotic stresses in plant roots, and on the importance of earlier and stronge r JA induction as a trait conferring better drought tolerant in legume varieties able to cope with water stress.

Dynamics of Arbuscular Mycorrhizal Fungi in Relation to Root Colonization, Spore Density, and Soil Properties among Different Spreading Stages of the Exotic Plant Threeflower Beggarweed (Desmodium triflorum) in a Zoysia tenuifolia Lawn
TL;DR: The results provide strong evidence that D. triflorum possessed a more intense AMF infection than Z. tenuifolia, thus giving rise to the altered host contributions to sporulation, soil AMF communities, relations of soil properties, spore densities, and root colonizations of the two plants, all of which are pivotal for the successful invasion of D.triflorums in lawns.

The northward shifting neophyte Tragopogon dubius is just as effective in forming mycorrhizal associations as the native T. pratensis
Roy H. A. van Grunsven,Tri Wira Yuwati,George A. Kowalchuk,Wim H. van der Putten,Elmar Veenendaal +4 more
TL;DR: Testing whether Tragopogon dubius, a species that has recently expanded its range northward and colonised the Netherlands, is able to associate with the same AMF as the native congener T. pratensis concludes that the range-shifting T. dubius is as effective in the formation of mycorrhiza as thenative congener.

Resource limitation is a driver of local adaptation in mycorrhizal symbioses

TL;DR: Results indicate that Andropogon ecotypes adapt to their local soil and indigenous AM fungal communities such that mycorrhizal exchange of the most limiting resource is maximized.

Soil type and land use intensity determine the composition of arbuscular mycorrhizal fungal communities

TL;DR: Land use intensity and soil type strongly affected AMF community composition as well as the presence and prevalence of many AM fungi, and future work should examine how the differences in AMF species compositions affect important ecosystem processes in different soils.

Preferential allocation to beneficial symbiont with spatial structure maintains mycorrhizal mutualism.
TL;DR: This work demonstrates preferential allocation of photosynthate by host plants to the more beneficial of two AM fungal symbionts and suggests that preferential allocation within spatially structured microbial communities can stabilize mutualisms between plants and root symbiont.
