In the Arabidopsis thaliana mitochondrial genome the gene coding for subunit 4L of NADH dehydrogenase (nad4L) is located between exon c of the nad5 open reading frame and orf25. The physical proximity of these genes further supports the trans-splicing model for assembly of the nad5 mRNA. Some transcripts comprise the nad4L open reading frame cotranscribed with nad5 exon c and orf25, while other mRNAs contain only nad4L and orf25. Both open reading frames for nad4L and orf25 are edited in several positions with different frequencies.
在拟南芥线粒体基因组中，编码NADH脱氢酶亚基4L（nad4L）的基因位于nad5开放阅读框的外显子c和orf25之间。这些基因在物理位置上的接近进一步支持了nad5 mRNA组装的反式剪接模型。一些转录本包含与nad5外显子c和orf25共转录的nad4L开放阅读框，而其他mRNA仅包含nad4L和orf25。nad4L和orf25的两个开放阅读框在几个位置以不同频率进行编辑。
