Biotechnology of reproductive onset: A new era for accelerated tree breeding

When compared with many annual crop plants, tree domestication is in its infancy. One of the main reasons for the slow progress towards tree domestication is that the lengthy juvenile period prevents trees from early sexual reproduction that is needed to develop pedigreed offspring. Thus, the control of reproductive onset is of great scientific and commercial importance. Recent functional genomics studies have begun providing a framework for how first time and seasonal reproduction are regulated in poplar (Populus spp.).
