is a fast-growing, large tree and one of the largest North American hardwood trees. In this study, the complete chloroplast (cp) genome sequence of is characterized. The whole cp genome was assembled to 156,867 bp, including a large single copy (LSC) region of 85,534 bp, a small single copy (SSC) region of 16,513 bp and a pair of inverted repeats (IRs) region of 27,410 bp. The base content of the cp genome is A (32.0%), T (31.3%), C (18.0%), and G (18.7%), and AT bases occupy a large proportion of the cp genome. The neighbor-joining phylogenetic analysis with 20 cp genomes from the Salicaceae family showed that is sister to . These will provide for the evolutionary and biological studies in Salicaceae family.
是一种生长迅速的大树，也是北美最大的硬木树之一。在本研究中，对其完整的叶绿体（cp）基因组序列进行了表征。整个cp基因组组装后为156,867 bp，包括一个85,534 bp的大单拷贝（LSC）区域、一个16,513 bp的小单拷贝（SSC）区域和一对27,410 bp的反向重复（IR）区域。该cp基因组的碱基含量为A（32.0%）、T（31.3%）、C（18.0%）和G（18.7%），且AT碱基在cp基因组中占很大比例。与杨柳科20个cp基因组进行的邻接法系统发育分析表明，与 是姐妹关系。这些将为杨柳科的进化和生物学研究提供依据。
