Arbuscular mycorrhizal fungi (AMF) can be benefcial for improving restoration of radioactive-cesium (137Cs)-contaminated soils through soil remediation. However, there has been no information on species diversity and the composition of AMF communities in 137Cs-contaminated soil after the FukushimaDaiichi Nuclear Power Plant (NPP) disaster. We examined the community dynamics of indigenous AMF
colonizing roots of napiergrass (Pennisetum purpureum) in two diferent 137Cs-contaminated land-use felds (grassland and paddy feld) by an Illumina MiSeq sequencing investigation within a 30-km radius around the Fukushima-Daiichi NPP in 2013 (sampling year 1) and 2014 (sampling year 2). We found nine AMF families, including Glomeraceae, Gigasporaceae, Paraglomeraceae, Claroideoglomeraceae,
Acaulosporaceae, Archeosporaceae, Ambisporaceae, Diversisporaceae and uncultured Glomeromycotina in roots. Glomeraceae was the most abundant in both grassland and paddy feld, followed by Paraglomeraceae. The diversity of AMF in grassland and paddy feld was higher in 2014 than in 2013. Furthermore, the AMF community structure was impacted by sampling year and land-use type. The AMF community structures colonizing napiergrass roots were also signifcantly impacted by landuse type and year throughout the 2-year investigation. To our knowledge, our results are the frst report to reveal the community dynamics of indigenous AMF in the 137Cs-contaminated felds around NPP. |
