To survive winter, trees must time spring growth with great precision. New research from Umeå Plant Science Centre shows that trees also use warm interruptions in early winter as signals, helping buds avoid opening too early.

Trees constantly have to balance growth with defence against attack. In her PhD research at Umeå University, Sara Rydman has identified several new genes linked to the formation of chemical defence compounds in aspen. The findings provide new insight into the genetic basis of chemical defence in trees.
