title: Genomics and the tree physiologist.
abstract: During the last decade, a strong case has been made for viewing trees as model systems in plant biology. More recently, forest biologists have argued for the sequencing of the genome of a forest tree. Now, the United States Department of Energy has announced plans for sequencing the genome of the Populus trichocarpa clone, "Nisqually-1." Thus, forest biology is poised to enter an exciting period of scientific discovery. Embracing new technology and new research paradigms, however, is never easy. It is, therefore, timely to ask how tree physiologists will take advantage of the Populus genome data. We contend that the most attractive opportunities will arise through genome-wide research designed to: (1). examine the differences between trees and herbaceous annuals; (2). explore questions relating to the temporal and spatial scales that characterize the life histories and growth of trees; and (3). investigate cause-and-effect relationships that are intractable to conventional research methodologies. To highlight the potential applications of genomics in tree physiology, we briefly discuss each of these approaches.
