Coffee is one of the most popular beverages around the world. As one of the best-known coffee species, Liberian coffee ( Bull ex Hiern 1876) has a high resistance to leaf rust, a devasting disease caused by . However, there are few reports on the systematic position and phylogenetic relationship of at the chloroplast (cp) genome level. Thus, we successfully assembled its cp genome. The full length is 154,799 bp with a GC content of 37.48%. We have further annotated the cp genome and predicted 85 protein-coding genes together with 8 rRNAs and 37 tRNAs. Furthermore, a large single copy region (LSC), a small single copy region (SSC), an inverted repeat region a (IRa) and an inverted repeat region b (IRb) are identified with lengths of 84,868 bp, 18,121 bp, 25,905 bp and 25,905 bp, respectively. The phylogenetic tree indicates that is closely related to , which is consistent with a previous result obtained from genotyping-by-sequencing.
咖啡是全球最受欢迎的饮品之一。作为最知名的咖啡品种之一，利比里亚咖啡（Bull ex Hiern 1876）对叶锈病具有高度抗性，叶锈病是由……引起的一种毁灭性病害。然而，关于……在叶绿体（cp）基因组水平上的系统位置和系统发育关系的报道很少。因此，我们成功组装了其cp基因组。全长为154,799 bp，GC含量为37.48%。我们进一步注释了cp基因组，并预测了85个蛋白质编码基因以及8个rRNA和37个tRNA。此外，还鉴定出一个大单拷贝区域（LSC）、一个小单拷贝区域（SSC）、一个反向重复区域a（IRa）和一个反向重复区域b（IRb），长度分别为84,868 bp、18,121 bp、25,905 bp和25,905 bp。系统发育树表明……与……密切相关，这与先前通过测序进行基因分型得到的结果一致。
