“…The findings of the present study on stress-induced alterations in nutrient concentrations agree with data in the literature, on the account that nutrient concentrations in plants decreased due to water stress (Amiri et al 2017a;Mahdavi et al 2018). As documented by Nikbakht et al (2014) in perennial ryegrass and by Mahdavi et al (2018) in tall fescue, AMF symbiosis enhances the uptake of mineral nutrients including N, P, K, and Zn.…”

Given the anticipation of water supply becoming increasingly scarce in the future and costlier, water conservation in turfgrass management has become extremely important. The application of mycorrhizal fungi in water scarcity has been considered as one of the most promising methods to improve turfgrass management. Accordingly, the present study evaluates the potential role of arbuscular mycorrhizal fungi (AMF) inoculation in the growth of two turfgrass species under water stress conditions. Two turfgrass species (Kentucky bluegrass [Poa pratensis] and perennial ryegrass [Lolium perenne L.]) were subjected to two watering regimes (well-watered [watering 100% field capacity] and water deficit [watering 50% field capacity]) in the presence of AMF (a mixture of Funneliformis mosseae and Rhizophagus irregularis, or non-inoculated plants [non-AMF] as control) and humic acid spray treatments (0 mg/L and 500 mg/L). Not surprisingly, lack of water resulted in diminished morphological traits, mineral nutrient concentrations, chlorophyll and carotenoid contents, relative water content, and enzyme activities, and increased proline content, malondialdehyde, and hydrogen peroxide concentrations in both turfgrass species. On the other hand, AMFinoculated plants grown under well-watered conditions showed increased plant biomass, phosphorous concentration, and relative water content compared to non-AMF plants. Further, nitrogen and potassium concentrations and catalase activity were improved by humic acid. There was no significant difference in water stress tolerance between P. pratensis and L. perenne. In conclusion, the two turfgrass species showed a good response to AMF inoculation under water stress conditions, where humic acid was found to be less effective.

“…Inoculation of maize with AMF significantly improved the growth and ameliorated the decline to a considerable extent. AMF-mediated growth increases of plants under drought stress has also been reported by other researchers [28,[54][55][56][57][58][59]. Reduced water availability has been reported to affect the cellular division and proliferation by reducing the expression of key genes, such as tubulin and cyclin [60].…”

The role of arbuscular mycorrhizal fungus (AMF, Glomus versiforme) in amelioration of drought-induced effects on growth and physio-biochemical attributes in maize (Zea mays L.) was studied. Maize plants were exposed to two drought regimes, i.e., moderate drought (MD) and severe drought (SD), with and without AMF inoculation. Drought at both levels reduced plant height, and chlorophyll and carotenoid content, thereby impeding photosynthesis. In addition, drought stress enhanced the generation of toxic reactive oxygen species (ROS), including H2O2, resulting in membrane damage reflected as increased electrolyte leakage and lipid peroxidation. Such negative effects were much more apparent under SD conditions that those of MD and the control, however, AMF inoculation significantly ameliorated the deleterious effects of drought-induced oxidative damage. Under control conditions, inoculation of AMF increased growth and photosynthesis by significantly improving chlorophyll content, mineral uptake and assimilation. AMF inoculation increased the content of compatible solutes, such as proline, sugars and free amino acids, assisting in maintaining the relative water content. Up-regulation of the antioxidant system was obvious in AMF-inoculated plants, thereby mediating quick alleviation of oxidative effects of drought through elimination of ROS. In addition, AMF mediated up-regulation of the antioxidant system contributed to maintenance of redox homeostasis, leading to protection of major metabolic pathways, including photosynthesis, as observed in the present study. Total phenols increased due to AMF inoculation under both MD and SD conditions. The present study advocates the beneficial role of G. versiforme inoculation in maize against drought stress.

“…AMF increased the water and nutrition content available to their host plants, as well as total soluble sugars (osmotic adjustment), under water stress conditions in order to cope and recover from drought stress conditions [74]. In the present study, we observed that AM carob plants accumulated more total soluble sugars during the prolonged water stress and recovery conditions, likely to maintain high tissue hydration [10] and to increase the photosynthetic activity [35,53,75]. Hexoses function as osmoprotectants and signals to induce plant stress responses and reduce reactive oxygen species (ROS) damage [76].…”

“…The positive role of AMF on the net accumulation of nutrients in P was 10% in both NE and SE, while K was 40% in both ecotypes, and it was 21% in NE vs. 11% in SE for Na in leaves of AM plants. Studies reported that mycorrhizal symbiosis positively increased the concentrations of nutrients in several species under drought stress [53][54][55][56][57]. During the recovery condition, the nutrient uptake in the NE ecotype was quick and similar to that recorded under water stress compared to SE plants.…”

Irregular precipitation and drought caused an increase in tree mortality rates in multiple forest biomes with alterations in both ecosystem services and carbon balance. Carob (Ceratonia siliqua) growth and production in arid and semi-arid ecosystems are likely affected by climate change-induced droughts. Understanding the physiological responses of drought-induced early-stage tree death and strategies to enhance drought tolerance and optimize growth will help tree improvement programs. Mycorrhizal inoculation has a pronounced impact on plant growth, water absorption, mineral nutrition, and protection from abiotic stresses. However, a better understanding of these complex interconnected cellular processes and arbuscular mycorrhizal fungi (AMF)-mediated mechanisms regulating drought tolerance in plants will enhance its potential application as an efficient approach for bio-amelioration of stresses. The objectives of this work were to elucidate the different effects of autochthone AMF on inorganic solute and water content uptakes, organic adjustments (sugar and proteins content), leaf gas exchange (stomatal conductance and efficiency of photosystems I and II), and oxidative damage of two contrasting ecotypes of carob seedlings: coastal (southern ecotype (SE)) and in-land (northern ecotype (NE)) under control (C), drought (by cessation of irrigation for 15 days (15D)), and recovery (R) conditions. Our findings showed that AMF promoted growth, nutrient content, and physiological and biochemical parameters in plants of both ecotypes during C, 15D, and R conditions. After four days of recovery, stomatal conductance (gs), the maximum photochemical efficiency of PSII (Fv/Fm), water content, and plant uptake of mineral nutrients (P, K, Na, and Ca) were significantly higher in shoots of mycorrhizal (AM) than non-mycorrhizal (NM) control plants. Consequently, AMF reduced to a greater degree the accumulation of hydrogen peroxide (H2O2) and oxidative damage to lipid (malondialdehyde (MDA)) content in AM than NM plants in NE and SE, after recovery. Altogether, our findings suggest that AMF can play a role in drought resistance of carob trees at an early stage by increasing the inorganic solutes (P, K, Na, and Ca), water content uptake, organic solutes (soluble sugars and protein content), stomatal conductance, and defense response against oxidative damage during re-watering after drought stress.
