However, their commercial cultivation is still challenging because of compromised productivities under various environmental stress conditions. Therefore, elite strains capable of commercial production should be developed. Although, significant progress has been made in metabolic pathway engineering techniques, due to the complexity of metabolic and regulatory networks of algae, rational bioengineering remained inefficient for strain improvement. This review has assessed the role of Adaptive Laboratory Evolution (ALE) as a promising and cost-effective alternative approach in developing elite algae strains for improved carbon capture, enhanced biomass production, and improved metabolite productivities to meet the robust commercial needs.</p><h3>Recent Findings</h3><p>ALE involves selecting the mutant cells under controlled selection pressure, where cells are exposed to a sequentially rising set of stress conditions over multiple generations to finally adapt and evolve desired phenotypes. It leads to the activation of inactive pathways that are suitable for the survival of strain in stress conditions. A brief view of ALE-assisted cultivation techniques shows its specificity for specific goal to develop its product-oriented applications. Furthermore, involving biosensor and robotics in ALE technology has indicated the potential of ALE process as a robust technique to rapidly develop elite strains to meet rising environmental and industrial demands. </p><h3>Summary</h3><p>Assessment of ALE-assisted strain improvement has shown its potential to improve algae strains for the overproduction of desired products without using rational engineering methods. Besides, automation of ALE technology could be even a better strategy to make the evolution process of desired phenotype and product development process selective and time efficient. However, unavailability of selection pressure for some valuable phenotypes limits the widespread application of ALE for some phenotypes. </p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":528,"journal":{"name":"Current Pollution Reports","volume":"11 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143513399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In natural environments, plants are exposed to a complex mixture of pollutants and environmental stressors, and combined exposure to these factors can produce effects that differ significantly from those of individual influences. However, comprehensive reviews on BVOC emission resulting from exposure to air pollution and its interactions with environmental variables remain limited.</p><h3>Recent Findings</h3><p>Rapid industrialization has exacerbated air pollution, characterized by increased levels of ozone (O₃) and carbon dioxide (CO₂) in the atmosphere, along with extreme climatic events such as heat waves and droughts. These stresses induced by air pollution and environmental factors may trigger plant defense mechanisms, leading to adjustments in metabolism and respiration or may damage plant cells, ultimately affecting the composition and intensity of BVOC emissions.</p><h3>Summary</h3><p>This review highlights that O₃ generally stimulates BVOC emissions, with a relatively smaller effect on isoprene but notable sensitivity in sesquiterpenes. In contrast, elevated CO₂ levels can suppress emissions across the three BVOC types investigated. Warming significantly boosts emissions, while drought has little effect on isoprene but substantially enhances sesquiterpene emissions. These analyses are limited by substantial uncertainties due to data scarcity. Additionally, the combined effects of air pollutants and environmental variables vary by plant species, VOC types, and stressor intensities.
