“…Similar results were observed in Plectranthus amboinicus seedlings inoculated with Rhizophagus clarus and associated to a high dose of P (200 mg P•dm −3 of soil), which exhibited a significant increase in root biomass (174%) in relation to the control treatment [40]. On the other hand, Piper longum plants inoculated with various AMF species (Glomus fasiculatum, Acaulospora fovata, and Gigaspora margirata) showed a decrease in root development, especially for plants inoculated with AMF of the species Glomus fasiculatum [41].…”

Arbuscular mycorrhizal fungi (AMF) species and/or phosphorus addition in the soil can affect secondary metabolism production and growth in plants. This study evaluated these effects on Piper divaricatum culture, which presents an essential oil rich in phenylpropanoids. Growth parameters, leaf volatile composition, total phenolic content, and the enzymatic activity of lipoxygenase (LOX) and phenylalanine ammonia-lyase (PAL) were monitored. At 90 days post inoculation (dpi), the treatments with AMF and AMF + P were more effective in terms of the number and biomass of leaves. In addition, the AMF group had increased plant height and root length. Phenylpropanoid and methyl eugenol contents were higher at 30 dpi in the P and AMF + P association treatments. However, at 90 dpi, the plants with P addition at 20 mg·dm−3 and AMF + 200 mg of P dm−3 showed higher phenolic contents and PAL activity, respectively. All treatments increased LOX activity, especially with P addition at 200 mg dm−3. These results demonstrate that P and AMF can be applied to optimize leaf biomass and volatile compound production in P. divaricatum.

“…At P 0 and P 0.2 levels, AM fungi promoted chrysophanol, emodin, physcion, polydatin, and resveratrol accumulations, and the promote effect was better under P-deficient conditions than under adequate P conditions. AM fungi up-regulated expressions of resveratrol-associated synthases, thereby promoting resveratrol production AM fungi, after coexisting with host plants, are able to affect expressions of synthetic enzyme genes related to plant secondary metabolites (Zeng et al, 2013;Merlin et al, 2020;Oliveira et al, 2022;Sun et al, 2022a). The synthesis of resveratrol in P. cuspidatum is regulated by key enzymes such as resveratrol synthase (RS), stilbene synthase (STS), supposed stilbene synthase (CRS), and resveratrol-forming stilbene synthase (Zheng et al, 2021).…”

The medicinal plant Polygonum cuspidatum Sieb. Et Zucc is rich in stilbenes (e.g., polygonin and resveratrol) and anthraquinones (e.g., emodin) for the therapy of human diseases, while how to increase the growth and medicinal composition concentrations of P. cuspidatum has become an urgent issue. The aim of the present study was to evaluate the effects of inoculation with an arbuscular mycorrhizal (AM) fungus, Funneliformis mosseae, on plant growth, phosphorus (P) acquisition, medicinal component concentrations, and expressions of resveratrol synthesis-associated enzyme genes of P. cuspidatum at two P levels (0 M and 0.2 M). P supply (0.2 M) stimulated root AM fungal colonization rate. F. mosseae inoculation significantly improved growth performance (height, diameter, and biomass) and root morphology (diameter, length, and projected area), irrespectively of substrate P levels. P supply and F. mosseae distinctly increased soil acid and neutral phosphatase activities, as well as root P concentrations. P supply increased root physcion and resveratrol concentrations in inoculated and uninoculated plants, along with up-regulated expressions of PcCHS1, PcCRS1, PcRS11, and PcSTS. AM plants represented significantly higher root aloe-emodin, chrysophanol, emodin, physcion, polydatin, and resveratrol concentrations than non-AM plants irrespective of P levels, coupled with up-regulated expressions of PcCHS1, PcCHS2, PcRS11, PcRS, and PcSTS. It is concluded that 0.2 M P supply and F. mosseae inoculation promoted chrysophanol, physcion, polydatin, and resveratrol concentrations of P. cuspidatum, with the increase in resveratrol associated with up-regulated expressions of related genes.

“…In these pathways, the availability of nutrients such as N and P through the application of green manures can increase the intermediate compounds of EO biosynthesis such as NADPH, ATP and Acetyl-CoA [ 25 ]. Moreover, the availability of P enhanced the precursor compounds of terpenoids such as isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which play an important role in EO composition biosynthesis [ 37 ]. Dos Santos Marques et al [ 38 ] noted that the EO quality of Lippia alba (Mill) N.E.…”

Nowadays, the application of sustainable and eco-friendly fertilizers plays an important role in improving the essential oil (EO) quantity and quality of medicinal and aromatic plants. Hence, the study aimed to investigate the effects of green manures, organic manures and biofertilizers on the nutrient content, dry matter yield, EO productivity and quality of peppermint. The treatments included green manures [barley monoculture (Bm), hairy vetch monoculture (HVm) and replacement intercropping of 75%HV + 25%B, 50%HV + 50%B and 25%HV + 75%B], arbuscular mycorrhizal fungi (AMF) and vermicompost (VC). A 50%HV + 50%B green manure appears to be the most effective treatment, since it provides the greatest amount of nutrients (N and K, 18.8 g kg−1, and 18.1 g kg−1, respectively), the tallest plants (61.5 cm), the most nodes per plant (17.5), the lateral branches (24.4), the highest leaf greenness index (45.5) and dry yield (266.7 g m−2) in peppermint. Moreover, this treatment evidenced the larger EO content (1.8%) and EO yield (4.84 g m−2). Regardless of the treatments, the chemical composition of peppermint EO was characterized by menthol (32.35–37.73%), menthone (16.96–20.64%) and 1,8-cineole (6.18–7.78%). The maximum content of menthol and 1,8-cineole was obtained by the application of 50%HV + 50%B. Additionally, the highest content of menthone was observed in AMF treatment. These results indicate that the application of 50%HV + 50%B green manures could be suggested as an environmentally friendly strategy for improving EO quantity and quality of peppermint.
