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.
这是一篇关于林木基因组学的综述。在结构基因组学方面，已为多达40种林木构建了遗传图谱，检测到30多个具有商业重要性的数量性状位点（QTL），对一些林木分类群进行了比较作图，完成了杨树的全基因组测序，桉树的全基因组测序正在进行中。在功能基因组学方面，已迅速积累了来自多种树种多个组织的庞大EST数据库，对次生生长与木材形成、开花以及抗寒性的分子分析，为这些树种特异性发育过程的代谢途径提供了一些见解。文中讨论了树木基因组学的发展前景，这可能对加速中国的林木基因组学研究具有启示意义。
