“…Among the three nutrient uptakes analyzed, the mycorrhizal contributions to the uptake of P were higher than the uptake of N and K. AMF-inoculated plants were proved for escalated plant growth by an increase in N, P, and K uptake during drought stress [ 38 , 48 , 49 , 50 ]. Nitrogen and phosphorous are the principal nutrients of plant cells that render the cell characters by altering cell structure and functions for growth patterns [ 42 , 48 , 51 ]. AMF colonization enhanced P concentration under all treatments.…”

Drought stress remains the major constraint in affecting crop productivity in several arid and semi-arid areas highlighting climate change perspectives. Arbuscular mycorrhizal fungi (AMF) belong to a versatile class of plant–fungal symbiotic associations establishing drought stress alleviation. Nevertheless, the mechanistic mode of sustainable agriculture necessitates rigorous assessment for authentic and reproducible plant growth parameters. Understanding the plant growth promotion, root morphological changes, and nutrient uptake response in AMF-inoculated plants to drought is very important for sustainable agriculture. Therefore, conducted a meta-analysis of published research articles for determining the efficacy of AMF in alleviating drought stress. Overall analysis showed that AM inoculated plants had 49% higher plant growth promotion than the non-mycorrhizal plants under drought stress. Biomass analysis depicted the root dry weight increase by 49%, shoot dry weight increase by 54%, and total dry weight increase by 58% indicating plant biomass traits augmentation. Root morphological traits analysis corresponded to increased root length (37%), root surface (31%), and root volume (65%). Notably, nutrient uptake assessment showed variable increases in uptake patterns such as P uptake by 86%, N uptake by 35%, and K uptake by 46%. Furthermore, the prominent efficacy of AMF was significantly larger under drought for P uptake (p < 0.001) and root volume (p < 0.001) indicating the linear relationship between root length and P uptake. Thus, the present meta-analysis confirms that drought stress alleviation emancipated by AMF is mediated by root traits modification and phosphorous acquisition efficacy. Hence, meta-analyses along with experimental validations with field trial evaluations will certainly provide the AMF research for escalated applications for better plant productivity, stress alleviation, and sustainable agriculture.

“…Several studies have explained that AMF have the ability to absorb and transfer N to the nearby plants or host plants (Hodge and Storer, 2015; Battini et al, 2017; Turrini et al, 2018). Zhang et al (2018a) have demonstrated AMF mediated increased allocation of shoot biomass to panicles and grains through increased N and P redistribution to panicles particularly under low fertilizer levels. Translocation of N into seeds is enhanced from heading to maturity.…”

Role of Arbuscular Mycorrhizal Fungi in Plant Growth Regulation: Implications in Abiotic Stress Tolerance

Abiotic stresses hamper plant growth and productivity. Climate change and agricultural malpractices like excessive use of fertilizers and pesticides have aggravated the effects of abiotic stresses on crop productivity and degraded the ecosystem. There is an urgent need for environment-friendly management techniques such as the use of arbuscular mycorrhizal fungi (AMF) for enhancing crop productivity. AMF are commonly known as bio-fertilizers. Moreover, it is widely believed that the inoculation of AMF provides tolerance to host plants against various stressful situations like heat, salinity, drought, metals, and extreme temperatures. AMF may both assist host plants in the up-regulation of tolerance mechanisms and prevent the down-regulation of key metabolic pathways. AMF, being natural root symbionts, provide essential plant inorganic nutrients to host plants, thereby improving growth and yield under unstressed and stressed regimes. The role of AMF as a bio-fertilizer can potentially strengthen plants’ adaptability to changing environment. Thus, further research focusing on the AMF-mediated promotion of crop quality and productivity is needed. The present review provides a comprehensive up-to-date knowledge on AMF and their influence on host plants at various growth stages, their advantages and applications, and consequently the importance of the relationships of different plant nutrients with AMF.

“…AM have shown significant roles in the uptake of soil nutrients, especially of N and P, which can effectively promote the growth of host plants [6]. AM also increase allocation of shoot biomass through increased N and P redistribution to panicles, particularly under low fertilizer levels [24]. In this experiment, the seedlings receiving higher fertilizer doses resulted in higher nutrient accumulation.…”

Nursery productivity is an important factor in plantation forest sustainability. Seedling quality contributes significantly to plantation health. Fertilization regimes and pest and disease control are critical. However, environmental concerns have arisen as a result of the use of chemical fertilizers and pesticides. The ideal is to manage nurseries in an environmentally friendly manner while maintaining productivity. The utilization of plant growth-promoting microbes (PGPM) is seen as one option in this effort. It has been demonstrated elsewhere that arbuscular mycorrhizae (AM) can improve the growth and health of host plants. In this study, the effect of two AM products on the growth and health of Eucalyptus pellita seedlings in reduced fertilizer regimes was investigated. The results showed that the AM products were unable to compensate for reduced fertilizer regimes (both to 50% and 25%), in terms of seedling height and diameter, in E. pellita. Further research is needed to determine whether using AM products can reduce the need for fertilizers and/or pesticides.
