A team of researchers from the United Kingdom and the Netherlands has identified a mechanism that enables angiosperms (flowering plants) to sense and remember changes in their environment.
Plants’ memory function enables them to accurately coordinate their development in response to stress or to the changing seasons. For example, many plants remember the extended cold of winter, which ensures that they only flower in spring when warmer temperatures return.
One way they do this is through a group of proteins called PRC2 (polycomb repressive complex 2). In the cold these proteins come together as a complex and switch the plant into flowering mode…[READ MORE]
