“…Thus, in contrast to those non-host species with considerable growth repression by AMF which is used in weed control (Rinaudo et al 2010), sugar beet does not seem to show reduced fitness in an environment with a dominant presence of host species and active AMF mycelium networks in soil. Experimental evidence on the biomass response of non-host plants to established AMF in nearby plants differs depending on the plant species and both growth reduction (Matsumura et al 2007;Veiga et al 2013;Zhang et al 2019) and increase (Mnasri et al 2017) have been observed in the non-host species.…”

“…Information on how the presence of AMF in soil influences the performance of the non-host plants is scarce. Inconsistent results regarding mycorrhizal responsiveness have been reported in studies with non-host species from Caryophyllaceae (Stellaria media, Veiga et al 2012), Cyperaceae (Carex capillacea, Zhang et al 2019), Aizoaceae (Sesuvium portulacastrum, Mnasri et al 2017), andBrassicaceae (Arabidopsis, Brassica, Veiga et al 2013;Tong et al 2015). Both negative (Matsumura et al 2007;Veiga et al 2013;Zhang et al 2019) and positive (Mnasri et al 2017) responses have been observed.…”

The arbuscular mycorrhizal mycelium from barley differentially influences various defense parameters in the non-host sugar beet under co-cultivation

The interactions between arbuscular mycorrhizal fungi (AMF) and non-host species are poorly studied. Particularly scarce is information on members of the Amaranthaceae/Chenopodiaceae family. Sugar beet (Beta vulgaris) plants were co-cultivated with a host species (Hordeum vulgare) in the presence (+AMF) or absence of Rhizophagus intraradices to explore the hypothesis that the presence of an active, pre-established AMF mycelium induces defense responses in the non-host species. Biomass of sugar beet did not respond to the +AMF treatment, while its root exudation of organic acids and phenolic acids was drastically decreased upon co-cultivation with +AMF barley. The most conspicuous effect was observed on a wide range of potential defense parameters being differentially influenced by the +AMF treatment in this non-host species. Antioxidant defense enzymes were activated and the level of endogenous jasmonic acid was elevated accompanied by nitric oxide accumulation and lignin deposition in the roots after long-term +AMF treatment. In contrast, significant reductions in the levels of endogenous salicylic acid and tissue concentration and exudation of phenolic acids indicated that AM fungus hyphae in the substrate did not induce a hypersensitive-type response in the sugar beet roots and downregulated certain chemical defenses. Our results imply that the fitness of this non-host species is not reduced when grown in the presence of an AMF mycelium because of balanced defense costs. Further studies should address the question of whether or not such modulation of defense pattern influences the pest resistance of sugar beet plants under field conditions.

“…However, plots filled with all of sterilised soils indicated non-inoculated AM due to soil sterilised kill AM. Soils were sterilised in an autoclave oven for 120 min at 120ºC [24]. To ensure the effectiveness of the sterilization procedure and plants without-inoculated AM, AM colonisation was determined in the sterilized soils after plant harvest.…”

Phosphorus (P) acquisition strategies of plants to adapt to P limitation in primary forest ecosystems of karst regions remain unclear. Root phosphatase and arbuscular mycorrhizal (AM) fungi, involved in two common P acquisition strategies, were measured in two N 2 -fixing plants (Albiziaodoratissima and Cajanuscajan) growing in shrubland and primary forest soils with and without soil AM inoculation. Both plants cultivated in primary forest soils had lower AM colonisation and N 2 fixation rates but higher root acid phosphatase activity in the rhizosphere when compared with those in shrubland soils. Plants in shrubland soils predominantly exploit P resources by stimulating AM colonisation of roots, but do so by enhancing root phosphatase activity in primary forest soils. AM colonisation in both N 2 -fixing plants was positively correlated with N 2 fixation rates but negatively correlated with root acid phosphatase activity. Soil available P content was higher in both N 2 -fixing plants under soil inoculation with AM fungi than in the treatment without fungal inoculation; root and shoot P content did not vary significantly between treatments. AM fungi and phosphatase enzymes increase N 2 -fixing plants' capacity to obtain soil P, thus contributing to the decrease in soil P limitation in karst ecosystems.

About 18–29% of vascular plant species, e.g., important crops, are not involved in a symbiotic interaction with arbuscular mycorrhizal fungi (AMF). These species are known as “non-host” plants. However, these plants can be colonized under certain conditions and develop rudimentary AM (RAM) phenotypes, which often results in a decrease in plant growth and an increase in resistance to pathogens and insects. Several “symbiosis toolbox” genes that are present in the genome of host plants are conserved in non-host plants. Moreover, specific non-symbiotic genes can be brought into play for symbiosis in non-host plants. Altogether, the results show that molecular connections with the symbiosis machinery have still remained in non-host plants, which can enhance the prospect of engineering this functional trait for agricultural plants.
