Tree Memories: How Can Trees Remember Without a Brain?

Conifer trees are good at adapting to environmental challenges. Epigenetic memory, unlike the slow process of natural selection, allows trees to quickly adjust to challenges in their surroundings. Epigenetic memories are formed when trees experience stress such as temperature fluctuations, radiation exposure, and insect attacks. These memories can influence future responses and may even be passed on to subsequent generations. Studying epigenetic stress memory in long-lived species like conifers, which experiences many challenges over their lifetimes, is important. By understanding how these trees use epigenetic memory to survive, researchers can develop strategies to create forests that are more ready to face climate change and pest attacks.
