“…Pre-exposed P. generosa expressed fewer genes at a higher abundance relative to naïve geoducks, albeit functional annotation of these genes showed diverse regulatory processes in cellular quality control and homeostasis (Figure 3). A general decrease in transcription may be attributed to adaptive benefits under environmental change (Bultelle et al, 2021). For instance, mussels Mytilus californianus decrease gene expression when acclimated to dynamic thermal stress, as opposed to acute isothermal conditions, highlighting a lower transcriptional demand during intermittent exposures (Connor & Gracey, 2020).…”

Climate change exerts environmental pressures on marine life and is projected to continue to intensify in the near future (IPCC, 2021;Lotze et al., 2006). In particular, ocean acidification (OA), or the reduction of ocean pH due to absorption of atmospheric CO 2 , posits a major ecosystem and economic concern within highly eutrophic coastal estuarine regions (Ekstrom et al., 2015). OA affects essential

“…Alternatively, several metabolic terms are enriched in cluster three, in which genes are downregulated in M. edulis , upregulated in M. galloprovincialis and slightly upregulated in hybrids (though the regulation of glycolytic process is also enriched in cluster four). Absent from the collection of annotated G × E genes are any HSPs, which are a significant part of the heat stress response in Mytilids, especially HSP70 and HSP90 (Buckley, 2001; Bultelle et al., 2021; Clark et al., 2021; Lockwood et al., 2015). However, minimal upregulation of HSPs upon thermal acclimation has been reported in other marine invertebrates (Collins et al., 2020).…”

Interspecific hybridization can lead to myriad outcomes, including transgressive phenotypes in which the hybrids are more fit than either parent species. Such hybrids may display important traits in the context of climate change, able to respond to novel environmental conditions not previously experienced by the parent populations. While this has been evaluated in an agricultural context, the role of transgressive hybrids under changing conditions in the wild remains largely unexplored; this is especially true regarding transgressive gene expression. Using the blue mussel species complex (genus Mytilus) as a model system, we investigated the effects of hybridization on temperature induced gene expression plasticity by comparing expression profiles in parental species and their hybrids following a 2‐week thermal challenge. Hybrid expression plasticity was most often like one parent or the other (50%). However, a large fraction of genes (26%) showed transgressive expression plasticity (i.e. the change in gene expression was either greater or lesser than that of both parent species), while only 2% were intermediately plastic in hybrids. Despite their close phylogenetic relationship, there was limited overlap in the differentially expressed genes responding to temperature, indicating interspecific differences in the responses to high temperature in which responses from hybrids are distinct from both parent species. We also identified differentially expressed long non‐coding RNAs (lncRNAs), which we suggest may contribute to species‐specific differences in thermal tolerance. Our findings provide important insight into the impact of hybridization on gene expression under warming. We propose transgressive hybrids may play an important role in population persistence under future warming conditions.

“…Dados sugerem que a família das HSPs possui ainda uma diferenciação funcional em resposta a condições estressantes de temperatura (Martín-Folgar et al, 2015). São altamente conservadas e seu papel em diversos organismos já foi investigado (Scudiero et al, 2019;Gbotsyo et al, 2020;Bultelle et al, 2021).…”
