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.

Liquid crystal monomers (LCMs) of different chemical structures were widely detected in various environmental matrices. However, their health risk evaluation is lacking. Herein, three representative LCMs selected from 74 LCM candidates upon literature review and acute cytotoxicity evaluation, then Mus musculus exposed to the for 42 days at doses 0.5 50 μg/kg/d investigate hepatotoxicity mechanisms. Phenotypic histopathological results showed that (DTMDPB, MeO3bcH, 5OCB) induced hepatomegaly, only 5OCB fatty liver. DTMDPB MeO3bcH decreased total cholesterol (TCHO) triglyceride (TG) content, whereas increased TCHO, TG, alanine aminotransferase levels. Transcriptome molecular docking analysis revealed by agonizing farnesoid X receptor, resulting disruption unsaturated acid biosynthesis, ascorbic antioxidant pathways, circadian clock homeostasis. promoted inflammation altered acid, primary bile rhythm antagonizing aryl hydrocarbon receptor. antagonized peroxisome proliferator-activated receptors, leading liver caused steroid, cholesterol, terpenoid backbone biosynthesis pathways. This study provides references understanding with selection priority control LCMs.
