“…However, there were few relations between tanshinones concentration and mineral concentration in the present study (Tables 4-6). This is because mineral nutrition was supplied for photosynthesis, and then photosynthate was transferred to maintain the AM symbiosis [45]. Consequently, carbon was not enough the increase the biomass.…”

“…The AM symbiosis formation is mediated by gene expression and the production of chemical molecular signals both in plants and fungi [46]. Chemical defense is induced by gene expressions that manipulate their metabolism [1,45]. Therefore, tanshinones were produced as defense chemicals to resist AMFs inoculation.…”

Roots and rhizomes of Salvia miltiorrhiza (S. miltiorrhiza) are widely used for the treatment of cardiovascular diseases. Arbuscular mycorrhizal fungi (AMFs) have been shown to enhance plant growth and increase secondary metabolites concentration in many plant species. However, effects of AMFs on S. miltiorrhiza have not been explored. A pot culture was designed as one control (non-AMF) treatment and four AMFs (G.m, Glomus mosseae; G.a, Glomus aggregatum; G.v, Glomus versiforme; G.i, Glomus intraradices) treatments were performed in order to evaluate the effects of AMFs on plant growth, as well as phyto-active compounds' concentration of S. miltiorrhiza seedlings. Plants were harvested after 90 days: agronomic traits and concentration; and an accumulation of mineral elements, as well as phyto-active compounds were detected. All AMFs inoculated plants formed mycorrhizal structures, and an infection ratio; also, the intensity of inoculated roots was higher than 84.61% and 23.86%, respectively. Mycorrhizal dependency was above 144.62%. Seedlings with AMFs inoculation had significantly higher plant height, leather leaf length, top leaflet size, base leaflet length, taproot length, taproot diameter and biomass than those with non-AMF inoculation. In addition, inoculation with AMFs increased N, P, and K accumulation significantly, but barely had any effect on mineral elements' concentrations. AMFs inoculation also significantly improved tanshinones concentrations and stimulation in order to accumulate salvianolic acid B. G.v and G.i were effective for seedlings growth; G.m and G.i were also effective for phyto-active compounds. In total, S. miltiorrhiza inoculation with AMFs had positive effects on growth and active components, especially inoculation with G.v.

“…Sujata (2015) concluded that, S. persica is adapted to alkaline, non-saline or very saline soils. Arbuscular mycorrhizal fungi can strongly influence the metabolism of their host plant (Fontana et al, 2009). These are fungal symbionts that are well known to improve plant nutritional status by enhancing the uptake of essential nutrients and by improving the water supply through an increase in root surface area (Smith and Read, 1997).…”

Salvadora persica is a popular medicinal plant in the Middle East countries. It is well adapted to a wide range of habitats. In this study we have compared the effect of two different habitats (Al-ahsabah valley and Shada Mountain) in Al-Baha City, south west of Saudi Arabia on the content of some primary and secondary metabolites in S. persica. The results show that soil texture, soil moisture and organic matter contents varied in the studied regions. This variation was accompanied by differences in total count and distribution of Mycorrhizal spores in both studied habitats. Soil total count of mycorrhizal spores and root colonization percentage in Shada Mountain was significantly higher than that in AlAhsabah valley. Moisture content, carbohydrates, proteins and amino acids concentrations in leaves and roots of plants collected from Al-ahsabah valley were significantly higher than those collected from Shada Mountain. Gas chromatography mass spectrometry (GC-MS) analysis showed that benzene, (isothiocyanatomethyl) was the most abundant analyt in both extracts. There was a slight variation in the secondary metabolites pattern, where benzene, 1-isocyano-2-methyl-in extract of S. persica roots collected from Al-Ahsabah valley substituted with Benzyl nitrile in S. persica roots of Shada Mountain. Taken together we could conclude that, different habitats in the studied regions affect markedly the concentration of its primary metabolites and to less extent the secondary metabolites. Isolation of the active phytochemical constituents from plants of different habitats and studding of its biological activity will definitely give fruitful results.

“…Rootassociated microbes, such as AMF, affect herbivore-natural enemy interactions indirectly by altering plant phenotype (Rasmann et al, 2017;Tao et al, 2017). For instance, AMF increase the attractiveness of plants to natural enemies by changing the volatile emissions of their host plants (Guerrieri et al, 2004;Fontana et al, 2009;Hoffmann et al, 2011;Schausberger et al, 2012;Babikova et al, 2013). AMF also influence the searching efficiency of natural enemies, likely by changing plant size (Gange et al, 2003), and can improve natural enemy performance Bennett et al, 2016).…”

Mycorrhizae Alter Toxin Sequestration and Performance of Two Specialist Herbivores

Multitrophic species interactions are shaped by both top-down and bottom-up factors. Belowground symbionts of plants, such as arbuscular mycorrhizal fungi (AMF), can alter the strength of these forces by altering plant phenotype. For example, AMF-mediated changes in foliar toxin and nutrient concentrations may influence herbivore growth and fecundity. In addition, many specialist herbivores sequester toxins from their host plants to resist natural enemies, and the extent of sequestration varies with host plant secondary chemistry. Therefore, by altering plant phenotype, AMF may affect both herbivore performance and their resistance to natural enemies. We examined how inoculation of plants with AMF influences toxin sequestration and performance of two specialist herbivores feeding upon four milkweed species (Asclepias incarnata, A. curassavica, A. latifolia, A. syriaca). We raised aphids (Aphis nerii) and caterpillars (Danaus plexippus) on plants for 6 days in a fully factorial manipulation of milkweed species and level of AMF inoculation (zero, medium, and high). We then assessed aphid and caterpillar sequestration of toxins (cardenolides) and performance, and measured defensive and nutritive traits of control plants. Aphids and caterpillars sequestered higher concentrations of cardenolides from plants inoculated with AMF across all milkweed species. Aphid per capita growth rates and aphid body mass varied non-linearly with increasing AMF inoculum availability; across all milkweed species, aphids had the lowest performance under medium levels of AMF availability and highest performance under high AMF availability. In contrast, caterpillar survival varied strongly with AMF availability in a plant species-specific manner, and caterpillar growth was unaffected by AMF. Inoculation with AMF increased foliar cardenolide concentrations consistently among milkweed species, but altered aboveground biomasses and foliar phosphorous concentrations in a plant species-specific fashion. Increased herbivore sequestration of cardenolides followed AMF-mediated increases in foliar cardenolide concentrations. Aphid performance declined with increasing foliar cardenolide concentrations, while caterpillar survival increased with aboveground biomass. Our findings suggest that by altering plant phenotype, the availability of AMF in soil has the potential to influence both top-down (via sequestration) and bottom up (via plant defense and nutrition) forces that operate on herbivores.
