摘要测定了穗花杉叶绿体基因组全序列。基因组全长136 657 bp，缺少一个反向重复序列。基因组总GC含量为35.85%（蛋白质编码基因，36.90%; tRNA基因，53.31%; rRNA基因，52.99%;内含子，36.10%;基因间间隔区，31.03%）。助理Argotaenia叶绿体基因组包含118个独特的基因，其中蛋白质编码基因83个，tRNA基因31个，rRNA基因4个。10个蛋白质编码基因和6个tRNA基因有一个内含子，而ycf 3有两个。编码区占基因组长度的60.27%，基因密度为0.88个基因/kb。最大似然系统发育分析表明穗花杉属是红豆杉科红豆杉属的姐妹属。
Abstract The complete chloroplast genome sequence of Amentotaxus argotaenia was determined in this study. The genome is 136 657 bp in length and lacks one inverted repeat region. The overall GC content of the genome is 35.85% (protein-coding genes, 36.90%; tRNA genes, 53.31%; rRNA genes, 52.99%; introns, 36.10%; intergenic spacers, 31.03%). The A. argotaenia chloroplast genome contains 118 unique genes, including 83 protein-coding genes, 31 tRNA genes, and four rRNA genes. Ten protein-coding genes and six tRNA genes have one intron, while ycf3 contains two. The coding regions occupy 60.27% of the genome length and the gene density is estimated to be 0.88 genes/kb. A maximum likelihood phylogenetic analysis suggested that Amentotaxus is sister to Taxus within the Taxaceae family.
