“…As of 2014, the nuclear genomes of three mycorrhizal fungi ( L. bicolor, T. melanosporum and R. irregularis ) have been published (Martin et al ., , ; Tisserant et al ., ). This resource has provided unprecedented knowledge about the structure and functioning of the mycorrhizal fungal genomes and their interactions with plants (Martin & Selosse, ; Plett & Martin, ; Lanfranco & Young, ; Martin & Kohler, ). It has also led to the identification of master genes with crucial roles in symbiosis formation, such as those coding for mycorrhiza‐induced small secreted proteins (MiSSPs) controlling plant immunity and development (Kloppholz et al ., ; Plett et al ., , ,b).…”

1406I.1407II.1408III.1410IV.1411V.1413VI.1416VII.14181418References1419 Summary Almost all land plants form symbiotic associations with mycorrhizal fungi. These below‐ground fungi play a key role in terrestrial ecosystems as they regulate nutrient and carbon cycles, and influence soil structure and ecosystem multifunctionality. Up to 80% of plant N and P is provided by mycorrhizal fungi and many plant species depend on these symbionts for growth and survival. Estimates suggest that there are c. 50 000 fungal species that form mycorrhizal associations with c. 250 000 plant species. The development of high‐throughput molecular tools has helped us to better understand the biology, evolution, and biodiversity of mycorrhizal associations. Nuclear genome assemblies and gene annotations of 33 mycorrhizal fungal species are now available providing fascinating opportunities to deepen our understanding of the mycorrhizal lifestyle, the metabolic capabilities of these plant symbionts, the molecular dialogue between symbionts, and evolutionary adaptations across a range of mycorrhizal associations. Large‐scale molecular surveys have provided novel insights into the diversity, spatial and temporal dynamics of mycorrhizal fungal communities. At the ecological level, network theory makes it possible to analyze interactions between plant–fungal partners as complex underground multi‐species networks. Our analysis suggests that nestedness, modularity and specificity of mycorrhizal networks vary and depend on mycorrhizal type. Mechanistic models explaining partner choice, resource exchange, and coevolution in mycorrhizal associations have been developed and are being tested. This review ends with major frontiers for further research.

“…Understanding these transitions is a major focus of mycology (Hibbett et al, 2000;Bruns and Shefferson, 2004;Wolfe et al, 2012;Kohler et al, 2015).

But the emergence of an ectomycorrhizal symbiosis may well involve correlated changes in spore or sporocarp morphology, for example, perhaps a transition to ornamented spores .…”
