AbstractEarly-diverging fungi (EDF) are distinct from Dikarya and other eukaryotes, exhibiting high N6-methyldeoxyadenine (6mA) contents, rather than 5-methylcytosine (5mC). As plants transitioned to land the EDF sub-phylum, arbuscular mycorrhizal fungi (AMF; Glomeromycotina) evolved a symbiotic lifestyle with 80% of plant species worldwide. Here we show that these fungi exhibit 5mC and 6mA methylation characteristics that jointly set them apart from other fungi. The model AMF, R. irregularis, evolved very high levels of 5mC and greatly reduced levels of 6mA. However, unlike the Dikarya, 6mA in AMF occurs at symmetrical ApT motifs in genes and is associated with their transcription. 6mA is heterogeneously distributed among nuclei in these coenocytic fungi suggesting functional differences among nuclei. While far fewer genes are regulated by 6mA in the AMF genome than in EDF, most strikingly, 6mA methylation has been specifically retained in genes implicated in components of phosphate regulation; the quintessential hallmark defining this globally important symbiosis.

A greenhouse experiment was conducted to investigate the effects of the arbuscular mycorrhizal fungus Glomus mosseae on growth, metal accumulation and translocation of Festuca arundinacea for the phytostabilization of lead/zinc tailings in this study. The results showed that mycorrhizal inoculation substantially enhanced the growth of F. arundinacea and significantly decreased Pb and Cd concentrations in shoots. The bioconcentration factor and translocation factor values of Pb, Zn, Cu and Cd of F. arundinacea were much lower than 1, and inoculation further inhibited Pb, Cu and Cd translocation from roots into shoots, while enhanced Zn translocation. These results suggested that F. arundinacea inoculated with mycorrhizal might be a potential measure for revegetation of Pb/Zn tailings, especial for Pb, Cu and Cd stabilization, in northern China.
