Arbuscular mycorrhiza (AM), a symbiosis between plants and members of an ancient phylum of fungi, the Glomeromycota, improves the supply of water and nutrients, such as phosphate and nitrogen, to the host plant. In return, up to 20% of plant-fixed carbon is transferred to the fungus. Nutrient transport occurs through symbiotic structures inside plant root cells known as arbuscules. AM development is accompanied by an exchange of signalling molecules between the symbionts. A novel class of plant… 
Transcriptional Regulation of Arbuscular Mycorrhiza Development
The first transcription factors controlling AM-specific gene expression and AM development have been discovered, and cis-elements required for AM-responsive promoter activity have been identified, and an understanding of their connectivity and elucidation of transcriptional networks orchestrating AM development can be expected in the near future.
Mycorrhizal Association and Their Role in Plant Disease Protection
The role of mycorrhizal symbiosis in plant disease protection, with special emphasis on the my Corrhiza-induced resistance (MIR).
Chemical Signalling in the Arbuscular Mycorrhizal Symbiosis: Biotechnological Applications
Under deficient nutrient conditions, the host plant increases the production and exudation of strigolactones into the rhizosphere to promote fungal development, thus acting as a “cry for help” signal.
Recognition Signalling Between Arbuscular Mycorrhizal Fungi (AMF) and Plants
This document focuses on the signaling recognition between AMF and plants in each symbiosis phase and on the regulation mechanisms of the plant defense responses for the symbiosis establishment.
Arbuscular Mycorrhizal Fungi and their Value for Ecosystem Management
Arbuscular Mycorrhizal Fungi (AMF) are a group of obligate biotrophs, to the extent that they must develop a close symbiotic association with the roots of a living host plant in order to grow and
Fungal lipochitooligosaccharide symbiotic signals in arbuscular mycorrhiza
It is shown that Glomus intraradices secretes symbiotic signals that are a mixture of sulphated and non-sulphated simple lipochitooligosaccharides (LCOs), which stimulate formation of AM in plant species of diverse families and in the legume Medicago truncatula these signals stimulate root growth and branching by the symbiotic DMI signalling pathway.
Arbuscular Mycorrhizal Fungi (AMF) for Sustainable Rice Production
The present chapter discusses about the potentiality of AMF for rice cultivation and also confers the molecular insight and future perspective of this fungal association for sustainable rice production.

Arbuscular Mycorrhizal Symbiosis and Its Role in Plant Nutrition in Sustainable Agriculture
The contribution that AM symbiosis can play as an ecosystem service provider to guarantee host plant nutrition under abiotic stress conditions is highlighted, and the exploitation of arbuscular mycorrhiza in sustainable agriculture is discussed.
Spatiotemporal regulation of the arbuscular mycorrhiza symbiosis establishment
This work examines in more detail the role of two of these proteins known to be involved in the mycorrhizal process, the transcriptional factors NSP1 and NSP2 and highlights that SlNSP1 could be directly or indirectly regulated by the AUX/IAA protein, SlIAA27.


A Medicago truncatula phosphate transporter indispensable for the arbuscular mycorrhizal symbiosis
It is shown that MtPT4, a Medicago truncatula member of subfamily I, is essential for the acquisition of Pi delivered by the AM fungus, which leads to premature death of the arbuscules; the fungus is unable to proliferate within the root, and symbiosis is terminated.
Plant sesquiterpenes induce hyphal branching in arbuscular mycorrhizal fungi
Strigolactones are a group of sesquiterpene lactones, previously isolated as seed-germination stimulants for the parasitic weeds Striga and Orobanche, and a synthetic analogue, GR24, induced extensive hyphal branching in germinating spores of the AM fungus Gigaspora margarita at very low concentrations.
Nitrogen transfer in the arbuscular mycorrhizal symbiosis
Results of stable isotope labelling experiments are reported showing that inorganic nitrogen taken up by the fungus outside the roots is incorporated into amino acids, translocated from the extraradical to the intraradical mycelium as arginine, but transferred to the plant without carbon.
Signaling in the arbuscular mycorrhizal symbiosis.
The landmark cloning of three plant signaling proteins required for the development of the symbiosis has provided the first insights into a signaling pathway that is used by AM fungi and by rhizobia for their symbiotic associations with legumes.
A phosphate transporter from the mycorrhizal fungus Glomus versiforme
This work identifies a complementary DNA that encodes a trans-membrane phosphate transporter (GvPT) from Glomus versiforme, a VA mycorrhizal fungus, and confirms the function of the protein encoded by GvPT was confirmed by complementation of a yeast phosphate transport mutant.
Strigolactones Stimulate Arbuscular Mycorrhizal Fungi by Activating Mitochondria
It is concluded that strigolactones are important rhizospheric plant signals involved in stimulating both the pre-symbiotic growth of AM fungi and the germination of parasitic plants.
Co‐existing grass species have distinctive arbuscular mycorrhizal communities
Although grass species evenness changed in amended soils, AM fungal community composition in roots of a given grass species remained stable, and the results clearly confirm that an AMfungal host‐plant preference exists, even between different grass species.
Molecular genetics of the arbuscular mycorrhizal symbiosis.
A petunia mutant affected in intracellular accommodation and morphogenesis of arbuscular mycorrhizal fungi.
It is concluded that the PAM1 gene may play a specific role in intracellular accommodation and morphogenesis of the fungal endosymbiont.
A plant receptor-like kinase required for both bacterial and fungal symbiosis
The molecular basis for this convergence is identified by cloning orthologous SYMRK (‘symbiosis receptor-like kinase’) genes from Lotus and pea, which are required for both fungal and bacterial recognition.
