Transcriptional response of transposable elements to thermal stress in the Antarctic fish Trematomus bernacchii.

ABSTRACT: Global change and the associated increase in temperature raise serious concerns for the conservation of Antarctic marine biodiversity, which is particularly vulnerable due to the stenothermal nature and highly specialized adaptations of its fauna. Trematomus bernacchii (commonly named emerald rockcod), a Southern Ocean-endemic benthic fish, serves as a valuable model organism for investigating the molecular and physiological impacts of climate change in polar ecosystems. Transposable elements (TEs) are of particular interest, as they are known to become activated under stress and to influence genome plasticity and gene regulation. In this study, we examined the transcriptional response of TEs and their silencing mechanisms in the gills and liver of T. bernacchii specimens exposed to therma
