Zinc in plants: Integrating homeostasis and biofortification

Molecular Plant, Год журнала: 2021, Номер 15(1), С. 65 - 85

Опубликована: Дек. 22, 2021

Zinc plays many essential roles in life. As a strong Lewis acid that lacks redox activity under environmental and cellular conditions, the Zn2+ cation is central determining protein structure catalytic function of nearly 10% most eukaryotic proteomes. While specific functions zinc have been elucidated at molecular level number plant proteins, wider issues abound with respect to acquisition distribution by plants. An important challenge understand how plants balance between Zn supply soil their own nutritional requirement for zinc, particularly where edaphic factors lead lack bioavailable or, conversely, an excess bears major risk phytotoxicity. Plants are ultimate source human diet, deficiency accounts over 400 000 deaths annually. Here, we review current understanding homeostasis from physiological perspectives. We provide overview approaches pursued so far biofortification crops. Finally, outline "push-pull" model nutrition as simplifying concept. In summary, this discusses avenues can potentially deliver benefits both nutrition.

The rhizosphere is a microhabitat where there an intense chemical dialogue between plants and microorganisms. two coexist develop synergistic actions, which can promote plants’ functions productivity, but also their capacity to respond stress conditions, including heavy metal (HM) contamination. If HMs are present in soils used for agriculture, risk of uptake by edible with subsequent bioaccumulation humans animals detrimental consequences health. Plant productivity be negatively affected. Many bacteria have defensive mechanisms resisting metals and, through various complex processes, improve plant response HM stress. Bacteria-plant synergic interactions the rhizosphere, as homeostatic ecosystem disturbance, common soil. However, this hard achieve agroecosystems managed traditional practices, because concentrating on maximizing crop yield does not make it possible establish interactions. Improving knowledge mediated exudates secondary metabolites lead nature-based solutions health contaminated soils. This paper reports main ecotoxicological effects compounds (including several metabolites) produced plant-microorganism holobionts removing, immobilizing containing toxic elements.

Endophytic Nanotechnology: An Approach to Study Scope and Potential Applications

Frontiers in Chemistry, Год журнала: 2021, Номер 9

Nanotechnology has become a very advanced and popular form of technology with huge potentials. been well explored in the fields electronics, automobiles, construction, medicine, cosmetics, but exploration nanotecnology’s use agriculture is still limited. Due to climate change, each year around 40% crops face abiotic biotic stress; global demand for food increasing, nanotechnology seen as best method mitigate challenges disease management by reducing chemical inputs such herbicides, pesticides, fungicides. The these toxic chemicals potentially harmful humans environment. Therefore, using NPs fungicides/ bactericides or nanofertilizers, due their small size high surface area reactivity, reduces problems plant management. There are several methods that have used synthesize NPs, physical methods. Specially, we need ecofriendly nontoxic synthesis NPs. Some biological organisms like plants, algae, yeast, bacteria, actinomycetes, fungi emerged superlative candidates (also considered green synthesis). Among methods, endophytic microorganisms widely low metallic ions, which opens new possibility on edge nanotechnology. In this review, will discussed different top-down, bottom-up, (specially including microorganisms) mechanisms, forms magnesium oxide nanoparticles (MgO-NPs), copper (Cu-NPs), chitosan (CS-NPs), β-d-glucan (GNPs), engineered (quantum dots, metalloids, nonmetals, carbon nanomaterials, dendrimers, liposomes), molecular approaches various aspects. At level, nanoparticles, mesoporous silica (MSN) RNA-interference molecules, can also be tools carry genetic material during engineering plants. management, biosensors diagnose disease.

Zinc Biofortification in Food Crops Could Alleviate the Zinc Malnutrition in Human Health

Molecules, Год журнала: 2021, Номер 26(12), С. 3509 - 3509

Опубликована: Июнь 9, 2021

Micronutrient malnutrition is a global health issue and needs immediate attention. Over two billion people across the globe suffer from micronutrient malnutrition. The widespread zinc (Zn) deficiency in soils, poor intake by humans their diet, low bioavailability, consequences has led research community to think of an economic as well sustainable strategy for alleviation deficiency. Strategies like fortification diet supplements, though effective, are not economical most low-income countries cannot afford them, they vulnerable Zn In this regard, biofortification staple food crops with been considered useful strategy. An agronomic approach that uses crop fertilization Zn-based fertilizers at appropriate time ensure grain enrichment found be cost-effective, easy practice, efficient. Genetic biofortification, time-consuming, also highly effective. Moreover, Zn-rich genotype once developed can used many years without any recurring cost. Hence, both genetic very tool alleviating

The societal cost of micronutrient deficiency (MND) or the "hidden hunger" is in millions dollars/year, reducing GDP some countries by as much 11%. Zn an important for both plants and animals. An estimated 17% world population, around 1.1 billion people, are at risk zinc (Zn) deficiency. has been related to adverse pregnancy outcomes, stunted growth, premature deaths, immune system dysfunctions, neuro-behavioral disorders, recently with failure recover from COVID-19. These health risks associated have compelled FAO WHO recommend fortification diet. Correcting a challenge due several reasons. Close half agricultural soils deficient, chemical fertilizers costly ineffective. Developing Zn-rich crops through plant breeding genetic engineering challenging.
