Abstract
The complete chloroplast genome hemiparasitic plant (Schoepfiaceae), was determined in this study by assembly with whole-genome sequence data. The chloroplast genome is 118,743 bp in length with a typical quadripartite structure containing a pair of inverted repeats of 12,406 bp, separated by a large and a small single copy fragments of 84,168 bp and 9763 bp, respectively. The chloroplast genome contains 112 genes that consisting of 69 protein-coding, 27 tRNA, 4 rRNA and 3 pseudolized genes. All of the (except for A) and two tRNA (V-UAG and G-UCC) genes were found to be lost. The three pseudogenes are A, 15 and L-CAA. represents the early stages of chloroplast genome degradation along with its transition to heterotrophy in related taxa.
摘要
本研究通过全基因组序列数据组装确定了半寄生植物（铁青树科）的完整叶绿体基因组。叶绿体基因组长度为118,743 bp，具有典型的四分体结构，包含一对12,406 bp的反向重复序列，分别由84,168 bp的大单拷贝片段和9,763 bp的小单拷贝片段隔开。叶绿体基因组包含112个基因，由69个蛋白质编码基因、27个tRNA基因、4个rRNA基因和3个假基因组成。发现所有的（除了A）和两个tRNA（V-UAG和G-UCC）基因都丢失了。这三个假基因是A、15和L-CAA。代表了叶绿体基因组降解的早期阶段及其在相关类群中向异养的转变。
