De novo transcriptome assembly of the Perna viridis: A novel invertebrate model for ecotoxicological studies
Summary
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.
Mussels, particularly Perna viridis, are vital sentinel species for toxicology and biomonitoring in environmental health. This species plays a crucial role in aquaculture and significantly impacts the fisheries sector. Despite the ecological and economic importance of this species, its omics resources are still scarce. We generated a gill-specific reference transcriptome for Perna viridis using 292 million short Illumina reads from eight pooled gill tissue samples isolated from twenty-four individuals. The Trinity assembler generated 438,842 transcripts with an N50 of 1,958 bp. Several databases were employed in the annotation process. This dataset greatly expands the omics resources of bivalve databases and advances our knowledge of transcriptomics, molecular biology, environmental toxicology, and cancer research.

Revealing the Impact of Polystyrene Nanoplastics on Gill Tissues of the Intertidal Clam, Gafrarium Divaricatum (Gmelin, 1791) using Transcriptomics Approach
Researchers exposed intertidal clams to polystyrene nanoplastics and used transcriptomics to assess gill tissue impacts, finding 1,182 upregulated and 1,626 downregulated genes related to immune modulation, antioxidant defense, and apoptosis. Histopathological examination revealed structural damage to gill tissues including ciliary erosion, lamellae fusion, and lipofuscin accumulation. The study establishes a high-quality genomic resource for this clam species while demonstrating the ecotoxicological effects of nanoplastics on sessile marine bivalves.
Chromosome-Level Genome Assembly of the Blue Mussel Mytilus chilensis Reveals Molecular Signatures Facing the Marine Environment
Scientists assembled the first chromosome-level genome of the Chilean blue mussel, an important aquaculture species in South America. The genome revealed genetic adaptations related to immune defense, stress response, and shell formation that help the mussels survive in challenging marine environments. This genomic resource will support breeding programs and help researchers understand how mussels respond to environmental stressors including pollution.
