It’s a warm, sunny day in April, and all the trees are in bloom. But how did they know it was warm and sunny?

Winter takes its toll on living things. To protect themselves from the elements, bears hibernate, and trees go dormant. Biologists have observed what happens when trees become dormant, but up to now, they haven’t understood the underlying genetic mechanisms that enable them to start growing again.

A team led by molecular geneticists from Michigan Technological University has identified and characterized a gene that tells a tree when winter ends and a spring growing season begins.

They’ve named the gene—“Early Bud-Break 1,” since it helps awaken the plant cells responsible for growth from their winter sleep.

“The absence of EBB1 during dormancy allows the tree to progress through the physiological, developmental and adaptive changes leading to dormancy,” Busov explains, “while the expression of EBB1 in specific cell layers prior to bud-break enables reactivation of growth in the cells that develop into shoots and leaves and re-entry into the active growth phase of the tree.”
