“…The reason for this may be slow spread of fungal hyphae after germination of AMF spores due to water deficit. Our results agree with the findings of Gong et al (2014), who observed inhibition in AMF colonization in foxtail millet roots as a result of water stress, which could be attributed to reduced availability of carbon to the stressed plants (Subramanian, Charest 1995). Our results confirm the findings of Kadian et al (2013).…”

A pot culture experiment was carried out under greenhouse conditions to study the effect of potassium fertilizer (70 mg kg -1 , K1, and 100 mg kg -1 , K2) and arbuscular mycorrhizal fungi (Glomus mosseae and Acaulospora laevis) alone and in different combinations on water stress amelioration of Vigna mungo during three growth stages. Treatment of the plants with mycorrhizal fungi and potassium improved physiological parameters including chlorophyll concentration, membrane stability, phosphatase activity, leaf protein concentration and mycorrhization over the untreated control regardless of water stress treatments. Imposition of water stress at reproductive stage caused maximum reduction in membrane stability, leaf protein concentration, phosphatase activity and mycorrhization as compared to stress during other stages. Treatment combinations of G. mosseae + A. laevis + K2 and G. mosseae + A. laevis + K1 proved to be the best for promoting physiological and morphological parameters studied both in stressed and unstressed plants. A combination of G. mosseae and K2 was the best among double inoculation treatments while G. mosseae was the best among single treatments of either dose of potassium and A. laevis for stress alleviation and growth amelioration. Imposition of water stress during vegetative stage had the least effect on the physiological parameters studied, except for leaf area, which was adversely affected. Chlorophyll concentration was the most affected parameter by water stress at the pod formation stage.

“…In plants, ROS production and removal (e.g., O 2 − and H 2 O 2 ) are in a dynamic equilibrium state to maintain normal physiological and metabolic functions [78]. When plants are subjected to drought stress, this balance is disrupted, leading to an overproduction of ROS that will result in oxidative stress and consequently membrane lipid peroxidation, protein denaturation, nucleic acid chain fracture, cell membrane damage, and even cell death in severe cases [6,15,79]. Avoidance of oxidative stress by preventing ROS accumulation is the most effective way for mycorrhizal inoculated plants to cope with drought stress [80].…”

Catalpa bungei C.A.Mey. is a common ornamental timber species. Its survival and growth are greatly affected by water scarcity in arid and semi-arid areas of Northwest China. Evidence suggests arbuscular mycorrhizal fungus (AMF) may improve plant drought resistance. However, there is limited information on the systematic effects of AMF on drought resistance in C. bungei seedlings. Here, a pot experiment was used to explore the effects of inoculation with the AMF Rhizophagus intraradices on the growth and physiological performance of C. bungei under different water treatment conditions. Three water levels and two mycorrhizal inoculation treatments were used with factorial design. The results showed that drought stress noticeably affected the growth and physiological performance of C. bungei seedlings. However, inoculation with R. intraradices significantly ameliorated the growth, and alleviated the effects of drought stress. The growth parameters of AMF-inoculated seedlings significantly increased regardless of water status. AMF changed the biomass allocation in seedlings by reducing the root mass ratio (RMR) and root/shoot ratio. AMF-inoculated seedlings displayed higher gas exchange parameters, photosynthetic pigment concentrations, specific leaf area (SLA), but lower specific leaf weight (SLW), regardless of water status. AMF alleviated drought-induced oxidative stress by attenuating the excess generation of reactive oxygen species (ROS), especially H2O2 and O2−, in leaves. Inoculation with AMF under drought stress also dramatically augmented indole-3-acetic acid (IAA) and gibberellins (GA3) levels and the IAA/abscisic acid (ABA) and GA3/ABA ratios, but reduced ABA and zeatin (ZT) levels in leaves. AMF symbiosis improved root morphology and promoted the absorption of nitrogen (N) and phosphorus (P) in seedlings. We conclude that inoculation with R. intraradices is potentially useful for afforestation and cultivation of C. bungei in Northwest China. Furthermore, AMF improved soil structure by increasing the glomalin-related soil protein (GRSP) contents and the proportion of macro-aggregates (0.25–0.5 mm) in the rhizosphere soil.

“…Additionally, fertilized plants (Fm and Fv) indicated less MDA than control that indicates the fertilizers involvements in ROS metabolism 14,61,72 . In addition, mycorrhiza inoculation reduced the H2O2 and MDA concentration in foxtail millet leaves in drought 33 . In consistent with our results, Bidabadi et al (2017) 14 demonstrated a reduction in H2O2 content in vermicompost application.…”

This study's main purpose was to investigate the probable amelioration of limited irrigation conditions by soil amendments for lingrain plants. The experiment was accomplished as a completely randomized factorial design along with three replications. The first factor was green manure (without (Gc) and with Trifolium pratense (Gr)), the second factor consisted of Rhizophagus irregularis mycorrhiza (Fm), vermicompost (Fv), both of mycorrhiza and vermicompost (Fm+v) and none of them (Fc), and also the third factor was irrigation regime (full irrigation and late-season water limitation). Green manure, vermicompost and mycorrhiza single-use enhanced the plant performance under water limitation conditions in comparison with the control. However, in the presence of vermicompost, along with green manure or mycorrhiza developed a positive synergistic effect on most of the traits. Combining green manure with the dual fertilizer (Fm+v) resulted in the vermicompost and mycorrhiza synergistic effects, especially under limited irrigation. Consequently, the triple fertilizer (Gr×Fm+v) experienced the highest amount of LRWC, root colonization, leaf nitrogen, chlorophyll a, chlorophyll b, carotenoids, antioxidant enzymes activity, grain yield and oil yield, which would lead to more resistance of plants to limited irrigation conditions.
