Summary Liquid crystal monomers (LCMs), the integral components in manufacture of digital displays, have engendered environmental concerns due to extensive utilization and intensive emission. Despite their prevalence ecotoxicity, LCM impacts on plant growth agricultural yield remain inadequately understood. In this study, we investigated specific response mechanisms tobacco, a pivotal crop model plant, four representative LCMs (2OdF3B, 5CB, 4PiMeOP, 2BzoCP) through integrative molecular physiological approaches. The findings reveal impacts, with 4PiMeOP exerting most pronounced effects, followed by 2BzoCP, 2OdF3B. exposure disrupts photosynthetic apparatus, exacerbating reactive oxygen species (ROS) levels leaves, which turn triggers upregulation antioxidative enzymes synthesis antioxidant substances. Additionally, strongly stimulate expression genes involved abscisic acid (ABA) biosynthesis signalling pathways. AI‐assisted meta‐analysis implicates ABA as critical regulator tobacco LCMs. Notably, exogenous application alleviates LCM‐induced toxicities, highlighting role stress amelioration. Our study provides novel insights into toxicity tolerance plants, shedding light both harmful effects ecosystems potential adaptation responses. This is crucial develop sustainable systems reducing negative caused emerging organic pollutants.
