摘要报道了中国特有的孑遗植物--香榧（Torreya fargesii）的叶绿体基因组全序列。基因组全长137 075 bp，平均GC含量为35.47%。大反向重复序列的一个拷贝从该基因组中丢失。霸王箭竹叶绿体基因组编码118个独特的基因，其中trnI-CAU、trnQ-UUG、trnN-GUU三个基因是重复的。编码蛋白质、tRNA和rRNA基因分别占基因组的54.7%、1.9%和3.4%。含内含子的基因有17个，其中6个是tRNA基因。最大似然系统发育分析显示，香榧属和穗花杉属之间有很强的姐妹关系。
Abstract The complete chloroplast genome sequence of Torreya fargesii (Taxaceae), a relic plant endemic to China, is presented in this study. The genome is 137 075 bp in length, with 35.47% average GC content. One copy of the large inverted repeats is lost from this genome. The T. fargesii chloroplast genome encodes 118 unique genes, in which trnI-CAU, trnQ-UUG, trnN-GUU are duplicated. Protein-coding, tRNA and rRNA genes represent 54.7%, 1.9% and 3.4% of the genome, respectively. There are 17 intron-containing genes, of which 6 are tRNA genes. A maximum likelihood phylogenetic analysis revealed a strong sister relationship between Torreya and Amentotaxus.
