文摘Coal mining activities significantly impact the environment through water,soil,and air pollution of the surrounding areas.The dispersal of pollutants and the degradation of soil quality by toxic metals emitted from coal mining activities cause significant concerns worldwide,posing serious risks to ecosystems,human health,and vegetation.Restoration of quality of soil contaminated by toxic metals from coal mining is challenging due to the continuous increase in the concentration of toxic metals such as lead,copper,chromium,cadmium,and arsenic within the soil matrix.Conventional approaches utilized for the remediation of soil are often time-consuming and labour-intensive.In addition,they may lead to secondary pollution,particularly when applied at a large scale.Phytoremediation,a technique that utilizes plants with high metal accumulation capacity,has surfaced as a promising,eco-friendly strategy for remediating soil contaminated with toxic metals.These plants can absorb and sequester metals into above-and belowground tissues or stabilize them into less bioavailable forms within the rhizosphere.Species from families such as Brassicaceae and Asteraceae have demonstrated notable effectiveness in phytoremediation applications.The efficiency of phytoremediation can be further enhanced by applying organic and inorganic soil amendments to increase metal bioavailability and plant uptake.Moreover,genetic engineering has enabled the development of plants with improved metal tolerance and accumulation capacities.Complementing these approaches,microbial phytoremediation employs plant-associated microbes to facilitate metal uptake and transformation,increasing the overall remediation efficiency.Following remediation,biomass is proposed for value-added applications,including biochar,biogas,and recovery of metals for industrial reuse.This review summarizes the current progress,emerging strategies,and future prospects of phytoremediation for mitigating toxic metal pollution in coal mining-affected soils.Altogether,these approaches illustrate the potential of integrating circular bioeconomy principles in transforming phytoremediation as a sustainable strategy for mitigating toxic metal pollution in coal mining regions.

文摘With the changing climate and escalating population,there will be extreme pressure on agricultural food production to ensure global food security.Traditional agricultural practices have relied heavily on hazardous pesticides and chemical fertilizers to boost crop yields.However,their continuous and excessive use has caused significant harm to non-target organisms,including humans,while also leading to a severe decline in soil health due to their indiscriminate and unbalanced application.Hence,serious efforts are needed to control this mounting problem of soil and environmental pollution.One effective strategy involves using microorganisms capable of solubilizing nutrients and breaking down pesticides.These microorganisms improve crop nutrient absorption by solubilizing essential nutrients and simultaneously degrade pesticide residues in soil.Utilizing this ability of microorganisms to degrade agrochemicals,microbial remediation offers a dependable and economical method for reducing the effects of such unwarranted contaminants.This review presents an extensive overview of pesticide use as well as microorganisms in soil as pesticide degraders,nutrient mobilizers(phosphate(PO_(4)^(3-)-P),potassium(K),and zinc(Zn)),and plant growth promoters for preventing the unsustainable exploitation of natural reserves.This review aims to highlight the diverse benefits these microorganisms offer across various domains while presenting an exciting opportunity to advance sustainable agriculture and firstly establishes a connection between nutrient solubilization and pesticide degradation mediated by microorganisms.It also offers a comprehensive bibliographic review of the application of plant growth-promoting microorganisms for solubilizing nutrients,such as P,K,and Zn,and degrading pesticides as well.

文摘Climate change profoundly influences sulfur(S)nutrition,which plays a crucial role in plant growth,development,and responses to diseases.Climate-induced stress may impair plant growth,photosynthesis,pollen development,and reproduction.For instance,under high temperature stress,plant photosynthetic efficiency is reduced due to the overproduction of reactive oxygen species,denaturation of heat shock proteins,and alterations in various enzyme activities.Unlike drought stress,plants have developed only a few mechanisms to mitigate heat stress.Utilization of S is one of the efficient strategies to enhance plant tolerance against biotic and abiotic stresses.Plant-derived S-containing secondary metabolites play a vital role in plant-pest and plant-disease interactions in various plants.However,little is known about the roles of S and its management strategies in response to disease attack in wheat and barley under climate change.A deeper understanding of S-based strategies could contribute to sustaining plant health and productivity,thereby supporting global wheat and barley yields in the face of increasing climate change challenges.This review therefore focuses on the roles of S and associated management strategies utilized to support plant growth,development,and reproduction and enhance disease resistance and tolerance to abiotic stresses in wheat and barley under climate change.
