Transcriptomic Analysis Provides Insights into Candidate Genes and Molecular Pathways Involved in Growth of Mytilus coruscus Larvae
This paper is not about microplastics — it uses transcriptomic analysis to identify genes and molecular pathways that control growth and development in the marine mussel Mytilus coruscus, with applications for aquaculture.
De novo transcriptome assembly of the Perna viridis: A novel invertebrate model for ecotoxicological studies
Researchers created the first detailed gene reference map for the gill tissue of the Asian green mussel, an important species for monitoring ocean pollution. They identified over 47,000 gene sequences, including many related to immune defense and stress responses. This genetic resource will help scientists better understand how marine organisms respond to environmental contaminants like microplastics and heavy metals at the molecular level.
Exploring the Potential of Metatranscriptomics to Describe Microbial Communities and Their Effects in Molluscs
Metatranscriptomics revealed a more complete picture of mussel microbiomes — including bacteria, viruses, fungi, and protozoans — than traditional 16S sequencing alone. The approach also identified host genes whose expression changed with pathogen load, providing new insights into how molluscs respond to microbial infections.
Single and repetitive microplastics exposures induce immune system modulation and homeostasis alteration in the edible mussel Mytilus galloprovincialis
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.
Rapid epigenetic response to salinity stress in an invasive mussel, Mytilus galloprovincialis
Researchers exposed the invasive mussel Mytilus galloprovincialis to rapid salinity decreases and tracked DNA methylation changes over 24 hours, finding that epigenetic modifications continued to evolve throughout the stress period, indicating dynamic regulatory responses to acute environmental change.
Genomics and transcriptomics of the green mussel explain the durability of its byssus

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.
