Περίληψη:	The Mediterranean bath sponge Spongia officinalis is currently threatened by recurrent mortality incidents in its native habitats. Although elevated temperature has been indicated as the underlying factor triggering these events, the molecular mechanisms involved in the organism’s response to thermal stress are not yet described. We experimentally tested the effect of exposure to temperatures of varying intensity and span on the species’ gene expression profile, replicating thermal gradients encountered in coastal habitats of the Eastern Mediterranean. De novo transcriptome assembly was performed on data produced by an Illumina HiSeq next-generation sequencing (NGS) platform and gene expression analysis was conducted among the different experimental conditions. Our analysis revealed major shifts in the organism’s transcriptomic profile induced by temperatures corresponding to the standard seasonal maximum (27°C), triggering processes related to signal transduction and response to stimulus. Further elevation of temperature corresponding to local extremes (30°C) activated additional processes, including immune response and apoptosis. However, following prolonged exposure to the extreme temperature, signs of resilience were observed through overexpression of regular cellular functions. Our results highlight the generally recognized sensitivity of S. officinalis to environmental shifts, providing an insight into the molecular mechanisms involved in the process. Furthermore, they suggest an innate capacity for thermal tolerance at the current extremes, implying a combination of factors and not solely temperature as the lethal agent. This sheds light on the mechanisms of pressure induced by ocean warming to its most sensitive receptors, coastal sessile invertebrates.
