“…Mummey and Rillig (2006) observed a reduction of AMF diversity in response to C. stoebe invasion, whereas Lekberg et al (2013) showed that this invader supported a higher AMF abundance and diversity than multi-species native plant communities. Although most AMF associate with a wide range of hosts, the selectivity of some plant species for particular fungal symbionts exists (Helgason et al 2002;Holland et al 2014;Taylor et al 2015). The selectivity of an invasive plant for most efficient fungal partners may change AMF species richness and composition to facilitate invader and reduce native plant performance.…”

“…As a consequence, the native plants grown in such soils would have reduced performance (shoot mass, the concentration of elements in shoots, and photosynthetic parameters), compared to plants grown in soils from beneath native vegetation. Invasions of mycorrhizal S. gigantea and R. laciniata would have no effect on AMF abundance; however, given the existence of the selectivity and functional diversity in AM symbiosis (Helgason et al 2002;Smith and Read 2008;Holland et al 2014;Taylor et al 2015), we also expected AMF species composition alterations in soils overgrown by these plants.…”

Invasive plants affect arbuscular mycorrhizal fungi abundance and species richness as well as the performance of native plants grown in invaded soils

We studied the effects of invasions by three plant species: Reynoutria japonica, Rudbeckia laciniata, and Solidago gigantea, on arbuscular mycorrhizal fungi (AMF) communities in habitats located within and outside river valleys. Arbuscular mycorrhizal colonization, AMF abundance and species richness in soils were assessed in adjacent plots with invaders and native vegetation. We also quantified the performance (expressed as shoot mass, chlorophyll fluorescence, and the concentration of elements in shoots) of two common, mycorrhizal native plants, Plantago lanceolata and Trifolium repens, grown in these soils. The invasions of R. japonica, R. laciniata, and S. gigantea influenced AMF communities compared to native vegetation, but the changes depended on the mycorrhizal status of invaders. The effects of non-mycorrhizal R. japonica were the most pronounced. Its invasion reduced AMF abundance and species richness. In the plots of both mycorrhizal plants, R. laciniata and S. gigantea, we observed decreased AMF species richness in comparison to native vegetation. The AMF community alterations could be due to (i) depletion of organic C inputs to AMF in the case of R. japonica, (ii) plant secondary metabolites that directly inhibit or selectively stimulate AMF species, or (iii) changes in soil physicochemical properties induced by invasions. The effect of invasion on AMF abundance and species richness did not generally differ between valley and outside-valley habitats. The invasions affected photosynthetic performance and the concentrations of elements in the shoots of P. lanceolata or T. repens. However, the directions and magnitude of their response depended on both species identity and the mycorrhizal status of invaders.

SummaryData generated from next generation sequencing (NGS) will soon comprise the majority of information about arbuscular mycorrhizal fungal (AMF) communities. Although these approaches give deeper insight, analysing NGS data involves decisions that can significantly affect results and conclusions. This is particularly true for AMF community studies, because much remains to be known about their basic biology and genetics.During a workshop in 2013, representatives from seven research groups using NGS for AMF community ecology gathered to discuss common challenges and directions for future research. Our goal was to improve the quality and accessibility of NGS data for the AMF research community. Discussions spanned sampling design, sample preservation, sequencing, bioinformatics and data archiving.With concrete examples we demonstrated how different approaches can significantly alter analysis outcomes. Failure to consider the consequences of these decisions may compound bias introduced at each step along the workflow.The products of these discussions have been summarized in this paper in order to serve as a guide for any researcher undertaking NGS sequencing of AMF communities.

“…Concerning edaphic factors, soil pH, P, texture, and C:N ratio were shown, together with host identity, to be key drivers of the AMF colonizing roots in grassland, woodland and agricultural soils (Dumbrell et al 2010;Torrecillas et al 2012;Holland et al 2014;Jansa et al 2014).…”
