Sub-Zero Survival, Revealing How Plants Freeze – Drs David Livingston and Michael Wisniewski, USDA

biology, earth and environment

Watching plants return to life after a spell of cold winter weather can seem like a miracle. For over a century, biologists have understood that plant survival depends on a variety of co-dependent mechanisms, yet their methods for coping with temperatures far below freezing are still poorly understood. Dr David Livingston and Dr Michael Wisniewski of the US Department of Agriculture have provided fresh insights into these mechanisms, with the help of remarkably intricate imaging techniques.
