This is a review on forest tree genomics. In structural genomics, genetic maps have been constructed for up to 40 forest tree species, more than 30 commercially important QTLs have been detected, comparative mapping has been done for a few of forest tree taxa, and whole genome sequencing was completed for Populus and is under way for Eucalyptus. For functional genomics, huge EST databases from multiple tissues of a number of tree species have been rapidly accumulated, and molecular analyses on secondary growth and wood formation, flowering, and cold hardiness have given some insights into the metabolic pathways of those tree-specific development processes. The prospects of development in tree genomics are discussed, which may be implicative for accelerating forest tree genomics studies in China.
