In addition to their value for wood products, members of the genus Populus (poplars) provide a range of ecological services, including carbon sequestration, bioremediation, nutrient cycling, biofiltration and diverse habitats. They are also widely used model organisms for tree molecular biology and biotechnology. The sequencing of the poplar genome to an approximately 6x depth adds to a long list of important attributes for research. These include facile transformation, vegetative propagation, rapid growth, modest genome size and extensive expressed sequence tags. Here, we discuss how the genome sequence and transformability of poplar, together with its high levels of genetic and ecological diversity, are enabling new insights into the genetic programs controlling ontogeny, ecological adaptation and environmental physiology of trees.
除了其在木材产品方面的价值外，杨属（杨树）成员还提供一系列生态服务，包括碳固存、生物修复、养分循环、生物过滤和多样的栖息地。它们也是树木分子生物学和生物技术中广泛使用的模式生物。杨树基因组测序达到约6倍深度，这增加了一长串可供研究的重要特性。这些特性包括易于转化、营养繁殖、生长迅速、基因组规模适度以及大量的表达序列标签。在这里，我们讨论杨树的基因组序列和可转化性，以及其高度的遗传和生态多样性，如何为控制树木个体发育、生态适应和环境生理学的遗传程序带来新的见解。
