“…This result was consistent with the hypothesis that fertilizers, especially N and P, can reduce the mycorrhizal colonization [58]. For instance, in wheat plants in which Ca(H 2 PO 4 ) or DAP was used as P fertilization the mycorrhizal colonization was strongly decreased [59]. Mycorrhizal fungi can overcome the impact of different soil-borne pathogens and plantparasitic nematodes.…”

Effective biosafe management strategies are used to decrease world crop damage produced by plant-parasitic nematodes. This study evaluated the efficiency of hydroxyapatite nanoparticles (n-HAP) and mycorrhizal fungi to control the Meloidogyne incognita infecting tomato plants. Application of n-HAP significantly increased the juveniles’ mortality (195.67%) and egg hatching inhibition percentage (80.71%) compared to the untreated control, in vitro. Mycorrhizal and/or n-HAP treatments increased the plant growth parameters (root and shoot length, dry weight, and leaf area) and reduced the negative consequence of nematode infection. This may be due to indirect mechanisms through increasing plant nutrient uptake efficiency and increasing the internal plant resistance against nematode infection. In dual-treated plants, phosphorus, nitrogen, and calcium content recorded the highest value in the nematode-infected plants. Whereas the dual inoculation significantly increased mineral contents in tomato plants compared with control, this may induce the strength of the cell wall of the epidermal layer and cortex and consequently increase the plant resistance against nematode infection. Our results revealed that the application of the plant resistance-stimulants enhanced the plant growth parameters and internal nutrient content and reduced the nematode’s criteria. Consequently, the internal plant resistance against nematode infection was induced.

“…Their results suggest that AMF has a substantial role in uptake of Zn into cereals and the proportional contribution by the mycorrhizal pathway of uptake is dependent on plant species, as well as available soil Zn. Similarly, a recently published paper by Yazici et al (2021) showed that AMF impairments decreased shoot and grain Zn concentrations and increased cadmium build-up in wheat plants while mycorrhizal replenishment and colonisation promoted shoot and grain Zn accumulation.…”

Biofortification is a long-term strategy of delivering more iron (Fe) and zinc (Zn) to those most in need. Plant breeding programs within the CGIAR and NARS have made major advances in Fe- and Zn-dense variety development and there have been successful releases of new biofortified varieties. Recent research effort has led to a substantial improvement in our knowledge of Fe and Zn homeostasis and gene regulation, resulting in the identification of candidate genes for marker assisted selection. International cooperation between the agricultural and nutrition community has been strengthened, with numerous implementation and partnership strategies developed and employed over the years. The evidence on the effectiveness of Fe and Zn biofortified crops is slowly building up and the results are encouraging. Biofortification continues to be scaled out and further work is required to reach the general aim of eradicating the hidden hunger of Fe and Zn deficiency in the world’s population and ensuring nutritional security.

“…Root mycorrhizal colonization contributes up to 50% of plant Zn uptake ( Watts-Williams et al , 2015 ). Moreover, decreasing root mycorrhizal colonization results in massive increases in cadmium (Cd) accumulation in wheat ( Yazici et al , 2021 ). Particular attention should thus be given to the abundance and activity of mycorrhizal fungi in agricultural soils, to manage micronutrient nutrition and limit Cd accumulation in food crops ( Ma et al , 2021 ).…”

To provide sustainable, sufficient, and nutritious food to a growing population is a major challenge for agriculture and the plant research community. In this respect the mineral micronutrient content of food crops deserves particular attention. Micronutrient deficiencies in cultivated soils and plants are a global problem which adversely affects crop production, plant nutritional value as well as human health and well-being. In this review, we call for awareness on the importance and relevance of micronutrients in crop production and quality. We stress the need for better nutrition in human populations with micronutrients, not only in developing but also in developed nations, and describe strategies to identify and characterize new varieties with high micronutrient content. Furthermore, we explain how an adequate nutrition of plants with micronutrients impacts metabolic functions and the capacity of plants to express tolerance mechanisms against abiotic and biotic constraints. Finally, a brief overview and a critical discussion on the current knowledge, future challenges and specific technological needs for the research on plant micronutrient homeostasis are provided. Research in this area is expected to foster the sustainable development of nutritious and healthy food crops for human consumption.
