Environmental problems have always received immense attention from scientists. Toxicants pollution is a critical environmental concern that has posed serious threats to human health and agricultural production. Heavy metals pesticides are top of the list toxicants endangering nature. This review focuses on toxic effect heavy (cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn)) (insecticides, herbicides, fungicides) adversely influencing ecosystem (plant soil) health. Furthermore, accumulation pesticide residues in soils plants been discussed detail. In addition, characteristics contaminated soil plant physiological parameters reviewed. Moreover, diseases caused by exposure were also reported. The bioaccumulation, mechanism action, transmission pathways both emphasized. bioavailability uptake these contaminants considered. Meanwhile, synergistic antagonistic interactions between their combined effects discussed. Previous relevant studies included cover all aspects this review. information provides deep insights into understanding hazardous effects.

Zinc in plants: Integrating homeostasis and biofortification

Molecular Plant, Journal Year: 2021, Volume and Issue: 15(1), P. 65 - 85

Published: Dec. 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.

Endophytic Nanotechnology: An Approach to Study Scope and Potential Applications

Frontiers in Chemistry, Journal Year: 2021, Volume and Issue: 9

Published: May 25, 2021

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.

Molecular mechanisms underlying heavy metal uptake, translocation and tolerance in hyperaccumulators-an analysis

Environmental Challenges, Journal Year: 2021, Volume and Issue: 4, P. 100197 - 100197

Published: July 3, 2021

Phytoremediation is an economically viable green technology that utilizes hyperaccumulator plants to remove heavy metals (HM) from the soil. Hyperaccumulators are adept at sequestering high concentrations of HM in aerial parts and intracellular detoxification through cell wall binding, organic acids, chelation sequestration. Excess activate oxidative stress defense mechanisms initiate synthesis stress-related proteins plants. Plethora studies have assessed feasibility phytoextraction demonstrated biomass metal hyperaccumulation two basic requirements for making process efficient. However, biochemical pathways involved uptake, translocation sequestration these not fully understood. Thus, more fundamental understanding traits needed optimize phytoextraction. In this review, we aim focus on transport, accumulation common such as mercury (Hg), lead (Pb), cadmium (Cd), chromium (Cr), zinc (Zn), copper (Cu) Arsenic (As) We will also discuss prominent metallophytes their phytoremediation strategies. This study be helpful uptake by hyperaccumulators. It would assist gaining knowledge about adaptation strategy used achieve homeostasis.
