Annotation
Content:
After the major scientific advances in epigenetics during the last decade, it is now clear that epigenetic mechanisms play an important role in gene regulation, genome integrity, phenotypic plasticity, reproduction, and even evolution with the stable transmission of certain epigenetic marks over generations. This role seems even exacerbated in plants, sessile organisms that cannot escape environmental changes and stresses, and therefore evolved molecular mechanisms to cope with such constraints. The aim of this course is to deliver the current knowledge on plant epigenetics, its role in gene regulation, transposable elements silencing, stress response and its stable transmission through mitosis and even meiosis. It will involve theoretical lectures by internal and external experts. The practical classes will be based on research cases and will include biochemistry, molecular biology and bioinformatics.
