ClearWinter and Summer Variations in the Physiological Parameters of Two Scleractinian Corals in Sanya Bay
Not a microplastics paper — this study examines seasonal changes in the physiology of two coral species in Sanya Bay, China, finding that summer high temperatures and low salinity stress their symbiotic algae and trigger oxidative responses in the corals.
Polyethylene microbeads induce transcriptional responses with tissue-dependent patterns in the mussel Mytilus galloprovincialis
Researchers exposed fish to polyethylene microbeads and measured gene expression across tissues, finding tissue-dependent transcriptional responses that suggest microplastic ingestion affects multiple physiological systems in distinct ways.
Transcriptome wide analyses reveal intraspecific diversity in thermal stress responses of a dominant habitat‐forming species
Researchers examined transcriptome-wide diversity in how coral species respond to thermal stress, revealing intraspecific genetic variation that may influence resilience to warming oceans. The findings highlight the importance of genetic diversity within coral populations for predicting reef responses to climate change.
Symbiosis modulates gene expression of symbionts, but not hosts, under thermal challenge
This study used a model symbiotic system to test whether coral hosts buffer their intracellular algal symbionts from environmental stress, finding that symbiosis modulated symbiont gene expression but not host gene expression under thermal challenge. Understanding coral symbiosis stress responses provides context for how plastic pollution may interact with climate-driven coral bleaching.
Exposure to plastic debris alters expression of biomineralization, immune, and stress-related genes in the eastern oyster (Crassostrea virginica)
Researchers exposed eastern oysters to plastic debris during their first year of life and then analyzed changes in gene activity using RNA sequencing. They found that plastic exposure altered the expression of genes involved in shell building, immune response, and stress management. The study suggests that chronic contact with degrading plastics in the ocean can disrupt multiple biological processes in shellfish.
Sex and gametogenesis stage are strong drivers of gene expression in Mytilus edulis exposed to environmentally relevant plasticiser levels and pH 7.7
Researchers found that sex and reproductive stage were stronger drivers of gene expression in blue mussels than either ocean acidification or exposure to the plasticiser DEHP, underscoring the importance of accounting for biological variables in pollution studies.
Gene expression plasticity facilitates acclimatization of a long-lived Caribbean coral across divergent reef environments
Researchers conducted a four-year transplant experiment with Caribbean corals across three different reef environments in Belize and found that corals largely adapt their gene expression to match their new surroundings, suggesting flexibility is a key survival strategy in changing oceans. However, corals moved to heavily degraded nearshore environments showed high mortality, indicating the limits of this adaptability under severe stress.
Hub genes of Acropora hemprichii response to microplastics were screened based on bioinformatics
Researchers used bioinformatics to identify 26 microplastic-responsive hub genes in the coral Acropora hemprichii by comparing them to validated differential expression genes from zebrafish, constructing protein interaction networks to reveal the key molecular pathways through which corals respond to microplastic stress.
Physiological and transcriptomic analyses reveal critical immune responses to hypoxia and sulfide in the haemolymph of clam Tegillarca granosa
This paper is not relevant to microplastics research — it examines how hypoxia and sulfide exposure affect immune responses in blood clams (Tegillarca granosa) at a physiological and transcriptomic level.
Sea Anemones Responding to Sex Hormones, Oxybenzone, and Benzyl Butyl Phthalate: Transcriptional Profiling and in Silico Modelling Provide Clues to Decipher Endocrine Disruption in Cnidarians
Transcriptomic profiling of sea anemones exposed to sex hormones, oxybenzone, and benzyl butyl phthalate revealed gene expression changes linked to steroid biosynthesis and sterol signaling pathways, providing evidence of potential endocrine disruption mechanisms in cnidarians.
Exposure to global change and microplastics elicits an immune response in an endangered coral
Researchers examined how the combination of ocean warming, acidification, and microplastic exposure affects the endangered coral Acropora cervicornis over 22 days. They found that while individual stressors produced subtle gene expression changes, the combined multistressor treatment triggered the strongest response, particularly in genes related to innate immunity. The study suggests that microplastics may compound the effects of climate change on coral health by activating immune stress responses.
Tunicates have a complex, highly dynamic TNF superfamily
This paper is not relevant to microplastics research — it is a genomics study on the evolution of the Tumor Necrosis Factor Superfamily (TNFSF) in tunicates, focusing on gene duplication and immune function.
A Window of Vulnerability: Chronic Environmental Stress Does Not Impair Reproduction in the Swordfish Xiphias gladius
Using histological and transcriptomic approaches on Mediterranean swordfish, this study found that despite facing overfishing pressure and environmental contaminants, reproductively mature females showed no significant impairment of reproductive function compared to immature individuals, suggesting this species maintains reproductive resilience under chronic environmental stress.
Full-Length Transcriptome Maps of Reef-Building Coral Illuminate the Molecular Basis of Calcification, Symbiosis, and Circadian Genes
Full-length transcriptomes of four species of reef-building corals were sequenced using long-read technology to better understand the molecular basis of calcification, symbiosis, and daily rhythms. The data revealed more complete gene structures than previous short-read studies and provided new insights into coral biology. This genomic resource supports research into how corals might respond to climate change and ocean acidification.
Molecular mechanisms controlling physiological plasticity in marine mussels under the influence of natural and anthropogenic stress factors
This thesis project investigated the molecular mechanisms that help Mediterranean mussels cope with environmental stress, including both natural factors and emerging pollutants like microplastics. Understanding these stress responses could help predict how marine shellfish will fare as pollution and climate change intensify.
Anatomically-specific coupling between innate immune gene repertoire and microbiome structure during coral evolution
This study found that different coral species have distinct coupling between their immune gene repertoires and microbiome composition, suggesting evolutionary specialization of host-microbe relationships. Coral microbiomes are being disrupted by plastic pollution, making understanding baseline coral immunity relevant to assessing plastic pollution impacts on reef health.
Transcriptomic Analysis Provides Insights into Candidate Genes and Molecular Pathways Involved in Growth of Mytilus coruscus Larvae
