“…Although AMF have been shown to improve plant performance under salinity in many plant species ( Santander et al, 2019 ; Ait-El-Mokhtar et al, 2020 ; Amanifar and Toghranegar, 2020 ), responses of mycorrhizal E. prostrata plants to salinity, especially in terms of bioactive compounds, have not been addressed. In the present work, mycorrhizal colonization rate was markedly reduced after 4 weeks of plant growth due to the high saline level (200 mM NaCl), but not at the later stage of plant growth ( Figure 2 ).…”

“…Plant biomass is the most prominent and direct attribute showing symbiosis-mediated plant performance under salt stress. AM inoculation has been reported to enhance the growth characteristics of several plants subjected to saline conditions, such as lettuce ( Santander et al, 2019 ), date palm ( Phoenix dactylifera L.) ( Ait-El-Mokhtar et al, 2020 ), and the medicinal plant V. officinalis (L.) ( Amanifar and Toghranegar, 2020 ). These findings support that the beneficial effects of AM application on the growth of host plants under salinity are consistent with our observation (increased fresh shoot weight, leaf number, and leaf area) under moderate salinity.…”

“…In lettuce, AM inoculation elevated proline accumulation and the activities of antioxidants such as catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase, but lowered phenolic compound synthesis and oxidative stress with high growth in plants exposed to salt stress ( Santander et al, 2019 ). Recently, AMF have been demonstrated to increase growth, nutrient acquisition (P, K + , Mg 2+ ), and the ratios of total chlorophyll:carotenoids, Ca 2+ :Na + , Mg 2+ :Na + , and K + :Na + in the shoots of the medicinal plant Valeriana officinalis under salinity stress ( Amanifar and Toghranegar, 2020 ). The authors also showed a higher stimulated root proline, total soluble sugars, and total phenolics in the shoots of mycorrhizal plants subjected to saline conditions.…”

“…Four substances possessing strong antioxidant properties, namely, asiatic acid, ferulic acid, vanillin, and carnosol, were linked to rosemary plants treated with Rhizoglomus irregulare ( Seró et al, 2019 ). Amanifar and Toghranegar (2020) pointed out that moderate salt stress stimulated a higher valerenic acid production in the medicinal plant V. officinalis L., which was more profound in the plants colonized by Funneliformis mosseae . Intriguingly, the potential of AMF, in combination with salinity, has not been fully noticed yet ( Kapoor et al, 2017 ).…”

“…Intriguingly, the potential of AMF, in combination with salinity, has not been fully noticed yet ( Kapoor et al, 2017 ). AM application for the cultivation of medicinal plants in saline soils could be used to address the growing demand of medicinal plants for the pharmaceutical industry ( Amanifar and Toghranegar, 2020 ). Moreover, it may offer the possibility of re-utilizing salt-affected soils under agricultural systems.…”

Eclipta prostrata (L.) is an important and well-known medicinal plant due to its valuable bioactive compounds. Microorganisms, including arbuscular mycorrhizal fungi (AMF), and salinity could directly impact plant metabolome, thus influencing their secondary metabolites and the efficacy of herbal medicine. In this study, the role of different single AMF species (Funneliformis mosseae, Septoglomus deserticola, Acaulospora lacunosa) and a mixture of six AMF species in plant growth and physio-biochemical characteristics of E. prostrata under non-saline conditions was investigated. Next, the most suitable AM treatment was chosen to examine the impact of AMF on physio-biochemical features and polyphenol profiles of E. prostrata under saline conditions (100 and 200 mM NaCl). The findings indicated that AMF mixture application resulted in more effective promotion on the aboveground part of non-saline plants than single AMF species. AM mixture application improved growth and salt tolerance of E. prostrata through increasing the activity of catalase, peroxidase (at 4 weeks), proline, and total phenolic content (at 8 weeks). Such benefits were not observed under high salinity, except for a higher total phenolic concentration in mycorrhizal plants at 8 weeks. Through high-performance liquid chromatography, 14 individual phenolic compounds were analyzed, with wedelolactone and/or 4,5-dicaffeoylquinic acid abundant in all treatments. Salinity and mycorrhizal inoculation sharply altered the polyphenol profiles of E. prostrata. Moderate salinity boosted phenolic compound production in non-AM plants at 4 weeks, while at 8 weeks, the decline in the content of phenolic compounds occurred in uncolonized plants subjected to both saline conditions. Mycorrhization augmented polyphenol concentration and yield under non-saline and saline conditions, depending on the growth stages and salt stress severity. Plant age influenced polyphenol profiles with usually a higher content of phenolic compounds in older plants and changed the production of individual polyphenols of both non-AM and AM plants under non-stress and salt stress conditions. A better understanding of factors (involving mycorrhiza and salinity) affecting the phenolic compounds of E. prostrata facilitates the optimization of individual polyphenol production in this medicinal plant.

This research aimed to evaluate the combined effects of chemical, biological and organic fertilizers on several features of Satureja khuzistanica. As an aromatic plant with medicinal properties, endemic to Iran, S. khuzistanica was studied for essential oil (EO%) and composition. Spanning for two growing seasons (2017–2019), the experiments involved 13 nutritional treatments, ie, (a) control (C), (b) nitrogen, phosphorus and potassium (NPK; 50‐25‐25 Kg ha−1), (c) cattle manure (CM30; 30 ton ha−1), (d) CM60 (60 ton ha−1), (e) CM30 + NPK, (f) CM60 + NPK, (g) vermicompost (V5, 5 ton ha−1), (h) V5 + NPK, (i) Glomus mosseae (GM), (j) Glomus Intra (GI), (k) sulphur (S0; 0 Kg ha−1) + thiobacillus (T), (l) S250 + T (sulphur: 250 Kg ha−1, ) and (m) V5 + T. At full flowering stage, samples were taken from aerial segments of plants in all treatment groups. After shade‐drying, the samples were hydro‐distillated to obtain essential oil (EO) and were then evaluated by gas chromatography–mass spectrometry (GC–MS). The interaction between year and fertilizer, as two treatments, had a significant effect (P ≤ 0.01) on the oil percentage, oil constituents and essential oil yield (EO.Y) of S. khuzistanica. GM and S0 + T caused the highest oil percentage in the first (3.7%) and second year (3.9%), respectively. V5 + NPK and V5 + T resulted in a substantial rise in EO.Y in the first (30.4 kg ha−1) and second year (64.3 kg ha−1), respectively. Carvacrol was highest in the first (92.1%) and second year (95.2%), as a result of using V5 + T and NPK treatments, respectively. Biological and vermicompost fertilizers not only improved the amount of EO but also enhanced its quality and aroma, as reflected in the constituents of the EO. The GI treatment and the V5 + NPK treatment led to high amounts of K in the branches. Meanwhile, high S contents were measured in the branches in response to the V5 and the S250 + T treatments. These findings suggested that biofertilizers and organic fertilizers can benefit the cultivation of S. khuzistanica because, when combined together, they can enhance the percentage and phenolic compounds in the EO.
