Miq. naturally occurs in eastern Australia from New South Wales to north Queensland. After being introduced to China, it has become an important tree species of ecological shelter plantations in coastal areas of southern China. In this study, the complete chloroplast (cp) genome of was sequenced and analyzed based on the Illumina NovaSeq 6000 platform. The cp genome of was found to be 15,6129 bp in length, including a large single copy (LSC) region of 86,200 bp and a small single copy (SSC) region of 18,457 bp, which were separated by two inverted repeats (IRs) of 25,736 bp. The cp genome contains 132 genes, consisting of 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the cp genome was 36.34%. The phylogenetic analyses indicated that was closely related to and and clustered with 4 Betulaceae species.
米氏桉自然分布于澳大利亚东部，从新南威尔士州到昆士兰州北部。引入中国后，它已成为中国南方沿海地区生态防护林的重要树种。在本研究中，基于Illumina NovaSeq 6000平台对米氏桉的完整叶绿体（cp）基因组进行了测序和分析。发现米氏桉的cp基因组长度为156,129 bp，包括一个86,200 bp的大单拷贝（LSC）区域和一个18,457 bp的小单拷贝（SSC）区域，它们被两个25,736 bp的反向重复序列（IRs）隔开。cp基因组包含132个基因，由87个蛋白质编码基因、37个tRNA基因和8个rRNA基因组成。cp基因组的总体GC含量为36.34%。系统发育分析表明，米氏桉与[具体物种1]和[具体物种2]密切相关，并与4个桦木科物种聚在一起。
