NAD（P）H脱氢酶复合体由植物叶绿体基因组中的11个ndh基因编码。然而，ndh基因被截短或删除在一些自养Epidendroideae兰花cp基因组。为了确定基因缺失的进化时间和兰花中各种ndh基因的基因组位置，对香荚兰、杏兜兰、雪兜兰、台湾Cypripedium formosanum、长齿玉凤花、古迪耶拉fumata和Masdevallia picturata的cp基因组进行了测序;这些基因组代表香荚兰亚科、Cypripedioideae亚科、兰花亚科和Epidendroideae亚科。四个兰花cp基因组序列被发现含有一套完整的ndh基因。在其他基因组中，ndh缺失与已知的分类学或进化关系无关，并且缺失是在兰科植物分裂成不同亚科之后独立发生的。在缺乏cp编码的ndh基因的兰花中，鉴定了非cp定位的ndh序列。在微小丹心虫中，至少有10个截短的ndh基因片段被转移到线粒体基因组中。兰花ndh向mt基因组转移的现象在ndh缺失的兰花和含ndh的兰花中都存在。
The NAD(P)H dehydrogenase complex is encoded by 11 ndh genes in plant chloroplast (cp) genomes. However, ndh genes are truncated or deleted in some autotrophic Epidendroideae orchid cp genomes. To determine the evolutionary timing of the gene deletions and the genomic locations of the various ndh genes in orchids, the cp genomes of Vanilla planifolia, Paphiopedilum armeniacum, Paphiopedilum niveum, Cypripedium formosanum, Habenaria longidenticulata, Goodyera fumata and Masdevallia picturata were sequenced; these genomes represent Vanilloideae, Cypripedioideae, Orchidoideae and Epidendroideae subfamilies. Four orchid cp genome sequences were found to contain a complete set of ndh genes. In other genomes, ndh deletions did not correlate to known taxonomic or evolutionary relationships and deletions occurred independently after the orchid family split into different subfamilies. In orchids lacking cp encoded ndh genes, non cp localized ndh sequences were identified. In Erycina pusilla, at least 10 truncated ndh gene fragments were found transferred to the mitochondrial (mt) genome. The phenomenon of orchid ndh transfer to the mt genome existed in ndh-deleted orchids and also in ndh containing species.
