ClearTranscriptomic 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.
Different recovery patterns of the surviving bivalve Mytilus galloprovincialis based on transcriptome profiling exposed to spherical or fibrous polyethylene microplastics
Researchers used gene expression analysis to study how Mediterranean mussels respond to and recover from exposure to different shapes of polyethylene microplastics. They found that spherical and fibrous particles triggered distinct stress responses and different recovery patterns over a 14-day period. The study suggests that the shape of microplastics matters significantly in determining their biological impact on marine organisms.
Microplastics in the deep: Suspended particles affect the model species Mytilus galloprovincialis under hyperbaric conditions
Researchers exposed juvenile Mediterranean mussels to polyethylene microplastics at three concentrations and three pressure levels (1, 4, and 50 Bar) for 96 hours to simulate deep-sea conditions. Microplastics significantly reduced filtration rates and triggered oxidative stress, with transcriptomic analysis revealing pressure-dependent differences in how mussels respond to plastic exposure.
Integrated metabolomics and transcriptomics reveal the hormesis-like effects of polyethylene microplastics on Pisum sativum L
Researchers used integrated metabolomics and transcriptomics to investigate hormesis-like effects of microplastics — where low concentrations stimulate while higher concentrations inhibit biological processes. The multi-omics approach revealed complex dose-dependent molecular responses to microplastic exposure.
The Growth Inhibition of Polyethylene Nanoplastics on the Bait-Microalgae Isochrysis galbana Based on the Transcriptome Analysis
Researchers found that polyethylene nanoplastics (50 nm) significantly inhibited growth and reduced chlorophyll in the bait microalga Isochrysis galbana through oxidative stress and disrupted gene expression, while larger microplastics had no significant impact.
Transcriptomic analysis following polystyrene nanoplastic stress in the Pacific white shrimp, Litopenaeus vannamei
Researchers used transcriptomic analysis to study how polystyrene nanoplastics affect gene expression in Pacific white shrimp. They found that nanoplastic exposure activated lysosome pathways and disrupted genes involved in immune response, protein processing, and metabolism. The study provides molecular-level evidence that nanoplastics can interfere with multiple biological systems in commercially important shrimp species.
Combination of transcriptomics, metabolomics and physiological traits reveals the effects of polystyrene microplastics on photosynthesis, carbon and nitrogen metabolism in cucumber (Cucumis sativus L.)
Researchers used transcriptomics and metabolomics to investigate how polystyrene microplastics affect photosynthesis and carbon-nitrogen metabolism in cucumber plants. The study found that both 5-micrometer and 0.1-micrometer particles reduced photosynthetic capacity and disrupted metabolic pathways, though they did so through different molecular mechanisms involving distinct gene expression changes.
Distinguish the toxic differentiations between acute exposure of micro- and nano-plastics on bivalves: An integrated study based on transcriptomic sequencing
Researchers found that nanoplastics are more toxic than microplastics in mussels, causing severe inflammatory responses and greater oxidative stress, with transcriptomic analysis revealing contrasting gene expression patterns between the two particle sizes.
Uptake and transcriptional effects of polystyrene microplastics in larval stages of the Mediterranean mussel Mytilus galloprovincialis
Researchers exposed larval stages of a marine organism to polystyrene microplastics and measured gene expression changes, finding tissue-dependent transcriptional responses that suggest microplastics can affect development even at early life stages.
Microplastics induce dose-specific transcriptomic disruptions in energy metabolism and immunity of the pearl oyster Pinctada margaritifera
Pearl oysters (Pinctada margaritifera) exposed to three doses of polystyrene microbeads showed dose-dependent reductions in energy balance, and transcriptomic analysis revealed disruptions to pathways controlling immunity and energy metabolism that scaled with exposure concentration.

Researchers examined transcriptome-wide gene expression changes in Mediterranean mussels after single and repeated microplastic exposures, finding significant immune system modulation and disruption of cellular homeostasis. The study suggests that both short-term and chronic microplastic exposure can alter immune regulation pathways in filter-feeding bivalves, with repeated exposures showing cumulative effects.
