Rehder is endemic to the montane regions of Southwest China. Till now, phylogenetic relationships between and other closely related species remain unclear. In this study, we first characterized the complete chloroplast (cp) genome of . The whole cp genome was 121,841 bp in size, including one hundred and thirteen genes. Results of comparative cp genome revealed that only 1 and 2 was characterized by a considerable variation. Our phylogenetic analyses supported the monophyly of the genus and revealed a clear separation between and Tiegh. This study highlights the significance of using cp genomes to examine species boundaries among closely related fir species.
冷杉在中国西南部山区是地方性树种。到目前为止，它与其他近缘物种之间的系统发育关系仍不清楚。在本研究中，我们首次对冷杉的完整叶绿体（cp）基因组进行了特征分析。整个cp基因组大小为121,841 bp，包含113个基因。叶绿体基因组比较结果表明，只有1和2表现出相当大的变异。我们的系统发育分析支持冷杉属的单系性，并揭示了冷杉与铁杉之间的明显分化。本研究强调了利用cp基因组来检验近缘冷杉物种间物种界限的重要性。
