This study presents the complete sequence of chloroplast genome. This 148,009 bp long genome consist of 107 genes out of which 30 of them are tRNA, 4 rRNA. Fairly long inverted repeat regions (IR) and large single-copy (LSC) of length 29,807 and 86,358 bp, respectively, were detected. This means an exceptionally short single-copy (SSC) region with only 2037 bp. This truncation of the SSC is due to multiple translocation of genes to the mitochondrion as in majority of the Orchidaceae and especially in the genus Vanilla. The phylogeny presented here meaningfully places Vanillon within the orchid family.
本研究展示了叶绿体基因组的完整序列。这个长度为148,009 bp的基因组由107个基因组成，其中30个是tRNA，4个是rRNA。检测到相当长的反向重复序列区域（IR）和长度分别为29,807 bp和86,358 bp的大单拷贝区域（LSC）。这意味着存在一个异常短的单拷贝区域（SSC），只有2037 bp。SSC的这种截短是由于基因多次转移到线粒体中，就像大多数兰科植物尤其是香草属植物那样。这里呈现的系统发育关系有意义地将香草属置于兰科之中。
