“…The presence of AMF intraradical mycelium is unlikely to drive the difference with shoots, since (i) fungi did not always have higher d 13 C than shoots (especially for sorghum) and (ii) spore d 13 C did not correlate with the difference between roots and shoots. We rather favour that the 13 C enrichment typical of heterotrophic organs (Cernusak et al, 2009) not observed with sorghum, so that here too phylogenetic conservatism has limited influence (rejecting again prediction #4), by contrast with some other AMF traits (Powell et al, 2009;Chagnon et al, 2013). Moreover, exactly as for d 13 C, root d…”

“…Our study was mostly exploratory, but from the available literature we hypothesised that the AMF strains (#1) are the main determinants of d 13 C values of AMF spores and FA C16:1u5, and (#2) modify the C isotopic composition of the host plant, as compared with non-mycorrhizal controls. We expected (#3) the host plant's susceptibility to such modifications to be greater for C3 than for C4 species; finally, given that many functional traits in AMF tend to be similar among phylogenetically close relatives (Powell et al, 2009;Chagnon et al, 2013), we expected (#4) that related AMF would display similar isotopic trends.

“…Most of the research on this topic has focused on the functional roles of single microbial groups (e.g., specific species or organisms from the same genera) associated with plants, mostly because of methodological limitations to assess non-culturable microbial groups (Amann et al, 1995;Andreote et al, 2009). Examples of these inferences are related to specific microbial groups able to promote plant growth, such as nitrogen-fixing bacteria (Raymond et al, 2004) and mycorrhiza-forming fungi (Chagnon et al, 2013). However, a holistic view of this system highlights the importance of interactions occurring amongst distinct microbial groups, resulting in the coining of the term 'microbiome'.…”

A plethora of microbial cells is present in every gram of soil, and microbes are found extensively in plant and animal tissues. The mechanisms governed by microorganisms in the regulation of physiological processes of their hosts have been extensively studied in the light of recent findings on microbiomes. In plants, the components of these microbiomes may form distinct communities, such as those inhabiting the plant rhizosphere, the endosphere and the phyllosphere. In each of these niches, the "microbial tissue" is established by, and responds to, specific selective pressures. Although there is no clear picture of the overall role of the plant microbiome, there is substantial evidence that these communities are involved in disease control, enhance nutrient acquisition, and affect stress tolerance. In this review, we first summarize features of microbial communities that compose the plant microbiome and further present a series of studies describing the underpinning factors that shape the phylogenetic and functional plantassociated communities. We advocate the idea that understanding the mechanisms by which plants select and interact with their microbiomes may have a direct effect on plant development and health, and further lead to the establishment of novel microbiome-driven strategies, that can cope with the development of a more sustainable agriculture.

The cascade of events that occurs after a bacterial cell recognizes host plant results in major changes in cellular metabolism, including the accumulation of several secondary metabolites (Hahlbrock et al, 2003).…”
