The effects of exposure to microplastics on grass carp (Ctenopharyngodon idella) at the physiological, biochemical, and transcriptomic levels
Researchers exposed grass carp to microplastics at two concentrations for 21 days and observed liver damage, inhibited growth, and increased oxidative stress. Transcriptome analysis revealed over 1,500 differentially expressed genes related to immune response, metabolism, and cellular stress pathways. The study suggests that microplastic exposure can trigger broad physiological and molecular disruptions in freshwater fish.
Polystyrene nanoplastic induces oxidative stress, immune defense, and glycometabolism change in Daphnia pulex: Application of transcriptome profiling in risk assessment of nanoplastics
Researchers used transcriptome sequencing to examine how polystyrene nanoplastics affect gene expression in the water flea Daphnia pulex. After 96 hours of exposure, they identified 208 genes with altered expression levels, linked to oxidative stress, immune defense, and sugar metabolism pathways. The study provides molecular-level evidence that nanoplastic pollution can trigger multiple stress responses in freshwater organisms.
Comparative Transcriptome Combined with Morphophysiological Analyses Revealed Carotenoid Biosynthesis for Differential Chilling Tolerance in Two Contrasting Rice (Oryza sativa L.) Genotypes
Researchers used comparative transcriptomics to find that carotenoid biosynthesis is a critical pathway for cold tolerance in rice, with cold-tolerant varieties showing higher carotenoid gene expression and pigment accumulation that protects chloroplasts during chilling stress. This study focuses on plant biology and crop science with no direct connection to microplastic research.
Toxicity of environmental and polystyrene plastic particles on the bivalve Corbicula fluminea: focus on the molecular responses
Researchers exposed freshwater bivalves to environmental microplastics and nanoplastics collected from a river, as well as to laboratory polystyrene nanoparticles, and measured molecular-level responses. Gene expression analysis revealed that plastic particle exposure activated stress response and immune defense pathways in gill and visceral tissues. The study indicates that even environmentally relevant concentrations of plastic particles can trigger measurable biological stress in filter-feeding organisms.
Toxicological effects and transcriptome mechanisms of rice (Oryza sativa L.) under stress of quinclorac and polystyrene nanoplastics
Researchers found that combined exposure to polystyrene nanoplastics and the herbicide quinclorac caused greater toxicity to rice than either stressor alone, with transcriptome analysis revealing disrupted pathways in photosynthesis, oxidative stress response, and hormone signaling.
Oxidative stress and metabolic process responses of Chlorella pyrenoidosa to nanoplastic exposure: Insights from integrated analysis of transcriptomics and metabolomics
Researchers used integrated transcriptomics and metabolomics to reveal that the microalgae Chlorella pyrenoidosa responds to nanoplastic oxidative stress primarily through linoleic acid, glycine-serine-threonine, and arginine-proline metabolic pathways, identifying key driver genes that could be targeted through genetic engineering to reduce nanoplastic harm in aquatic ecosystems.
Decoding the molecular concerto: Toxicotranscriptomic evaluation of microplastic and nanoplastic impacts on aquatic organisms
This review summarizes existing research on how microplastics and nanoplastics affect gene activity in aquatic organisms including fish, crustaceans, and mollusks. The studies show that these tiny particles disrupt genes involved in immune defense, stress response, reproduction, and metabolism. Understanding these molecular-level changes is important because they reveal how microplastics could cause long-term health problems in animals that enter the human food chain.

Researchers investigated the combined effects of microplastics and tire particles on the water flea Daphnia magna, finding that the mixture triggered significant oxidative stress at environmentally relevant concentrations.

The study suggests that co-exposure to these common freshwater pollutants may pose greater ecological risks than either particle type alone.
The effects of Micro/Nano-plastics exposure on plants and their toxic mechanisms: A review from multi-omics perspectives.
A multi-omics review of micro/nanoplastic effects on plants found that plastic exposure disrupts gene expression, protein function, and metabolic pathways across multiple plant systems, with potential consequences for crop yield and agricultural food safety.
Transcriptomic and metabolomic changes in lettuce triggered by microplastics-stress
Researchers grew lettuce in water containing polystyrene microplastics and found that the particles accumulated in root tips and leaf veins, causing water loss stress and changes in gene expression. The plants responded by activating stress defense systems and altering their metabolism, including increased production of protective compounds in root secretions. This study provides molecular-level evidence that microplastics can stress food crops and change their biology, raising questions about the safety and nutritional quality of vegetables grown in contaminated environments.
