Research progress on the influencing factors and response mechanisms of plant adsorption of atmospheric particulate matter
Plants could effectively adsorb and remove particulate matter from the air,while could be suffered from the adverse effects.Therefore,exploring the interaction between plants and atmospheric particulate matter is crucial for profound understanding of ecological balance,microenvironmental climate,and environmental quality improve-ment.Few systematic literature have elaborated the adsorption and response mechanisms of atmospheric particulate matter by plants.We summarized the causes and composition of atmospheric particulate matter,as well as the ad-sorption methods and factors of plants on atmospheric particulate matter.Moreover,we elaborated the impact of at-mospheric particulate matter stress on phenotypic and physiological characteristics,as well as molecular mecha-nisms.For the future researches,we proposed 1)to select plant species with strong adaptability and high dust re-tention capacity.Subsequently,there should be a universal green dust retention plan on account of comprehensive factors such as plant community structure,street morphology,and planting space;2)to extend the research from urban areas to agricultural and pastoral areas,with a systematic analysis of the comprehensive dust retention capaci-ty of communities with different plant configuration;3)to effectively combine the dust retention capacity of plants with their own resistance.Subsequently,we should explore the physiological and molecular mechanisms of plants responding to atmospheric particulate matter stress and establish a comprehensive evaluation system and criteria;4)to develop in situ labeling detection technology,which would be a valuable tool for accurately tracing and quanti-fying the dynamics of atmospheric particulate matter within plant at the cellular level.
