Management of the Arbuscular Mycorrhizal Symbiosis in Sustainable Crop Production

Effectiveness of arbuscular mycorrhizal fungi inoculated on Canavalia ensiformis L. in Calcaric Histosol soils

“…The positive effect of the inoculation with R. intraradices / INCAM-11 on the biomass and nutritional contents of Jackbean was explained by the establishment of an effective arbuscular mycorrhizal symbiosis and its beneficial effects on nutrient uptake (Willis et al, 2013;Yang et al, 2014) and thus on crop biomass production. The percentage of mycorrhizal colonization found in treatments with R. intraradices was around 60 %, a result that Relaciones entre los porcentajes de colonización micorrízica con la producción de biomasa (A), los contenidos de N (B), P (C), K (D) y con el número de esporas de micorrizas reproducidas (E), en un suelo Calcaric Histosol de Santo Domingo, provincia de Villa Clara, Cuba, años 2012-2013. has been indicative of an efficient mycorrhizal functioning in most crops (Rivera et al, 2007) and in the Canavalia itself (Martín et al, 2015;García et al, 2017).…”

“…Mycorrhizal arbuscular symbiosis is widespred in most economically important crops, and approximately 80 % of plant species establish this type of symbiosis (van-der-Heidjen et al, 2015). Within the ecosystems, this type of symbiosis is recognized as an adaptation mechanism; it increases the plant's capacity to absorb nutrients and water, reduces pathogenic damages, and improving soil aggregates among other effects (Hamel and Strullu, 2006;Pozo and Azcón-Aguilar, 2007;Willis et al, 2013;Yang et al, 2014;Bagyara et al, 2015). However, it is a current challenge to achieve the proper management of this symbiosis through the inoculation of efficient strains in agricultural production.…”

Abundance of the arbuscular mycorrhizal fungal taxa associated with the roots and rhizosphere soil of different durum wheat cultivars in the Canadian prairies

“…Dominikia, the genus deemed detrimental to wheat based on a large correlation study (Dai et al 2014), had a higher relative abundance in soil than in roots, and Diversispora, a genus deemed beneficial to N and P uptake in wheat (Dai et al 2014), had a higher relative abundance D r a f t in roots than in soil. Extraradical development is essential for effective harvesting of soil resources, and intuitively, the growth form of the AM fungal associate of a plant should be a determinant of the growth-promoting value of the AM fungus.…”

“…The arbuscular mycorrhizal (AM) symbiosis plays an important role in the sustainability of agriculture. This symbiosis is a strategy used by many plant species for efficient extraction of soil nutrients (Yang et al 2014), protection against abiotic stress (Hassan et al 2013), and protection against root pathogens (Koide and Elliott 1989;Johnson and Graham 2013). Arbuscular mycorrhizas and other mutualists co-inhabiting roots could potentially be managed in agriculture in order to increase crop yields while reducing the dependence of crops on chemical fertilizers (Ellouze et al 2008;Fraser et al 2009).…”

“…Arbuscular mycorrhizas and other mutualists co-inhabiting roots could potentially be managed in agriculture in order to increase crop yields while reducing the dependence of crops on chemical fertilizers (Ellouze et al 2008;Fraser et al 2009). In spite of its value, the AM symbiosis is largely unmanaged in crop production (Ellouze et al 2014). In the face of the increasing global demand for food and bioproducts and the disappearance of easily exploitable phosphate sources, it is important to increase the nutrient efficiency of crops.…”
