Resumen:
Plants, including genetically modified (GM) ones, are able to shape the structure of soil microbiomes by modifying the soil properties and the rhizosphere chemistry by the exudation of different compounds, thus influencing the soil microbial dynamics. Among rhizospheric microorganisms beneficial to the plant community, the arbuscular mycorrhizal (AM) fungi are considered as indicators of soil health, playing important roles in plant growth by improving mineral nutrition, stabilizing soil aggregates and protecting their host plants against pathogens. In the context of a sustainable use of soils and conservation of the biodiversity of these beneficial fungi, a better understanding of the effects of GM plants on the mycorrhizal symbiosis is thus relevant. This chapter seeks to understand the effects of GM crops on AM fungi by reviewing the existing bibliography and to lay the foundation for further research works that enrich the current knowledge on this topic. Although to date most scientific investigations have found no significant effect of GM plants on AM fungal colonization, some found a negative effect of GM plants on the initial stages of the establishment of the mycorrhizal symbiosis. Thus, it is necessary to carry out further investigations on a long temporal scale and under different agro-ecological conditions, focusing on AM fungal biodiversity and on the impact of each GM crop on these beneficial microorganisms before authorizing release.
