植物线粒体转录本在两端都经历成熟过程。尽管经常观察到,成熟5 '端的转录后形成仍然知之甚少。我们现在分析了线粒体基因转录本的处理过程,线粒体基因编码细胞色素成熟系统的一个组成部分。拟南芥(Arabidopsis thaliana, Arabidopsis)有两种线粒体ccmc1配置,由位于ccmc1基因上游约500 bp的66 bp序列片段区分。在拟南芥中,这些不同的线粒体基因型与两种不同的5 '末端的产生相关,这两种末端相对于翻译起始密码子(C24ccmCgenotype)位于哥伦比亚(ColccmCgenotype)的- 484附近,或C24 (C24ccmCgenotype)的- 390附近。之前,我们鉴定了RNA加工因子3 (RPF3),这是一种五肽重复(PPR)蛋白,用于从colccmc基因型转录的- 484个5 '端ccmcmrna的成熟。现在我们确定了几个ccmc转录本成熟过程中有缺陷的接入。利用这种自然遗传变异,我们鉴定了RNA加工因子6 (RPF6),这是一种PPR蛋白,从c24ccmc基因型转录产生−390个5 '端ccmcmrna所必需的。Col - type和C24 - type都编码RPF3和RPF6,因此它们可以处理来自两种不同线粒体基因型的ccmc转录本。这些因子及其同源RNA识别位点在不同的ccmcc基因型中是一个有趣的例子,为ccmcc转录物的5 '成熟所需的两种共适应细胞核系统的进化提供了一个有趣的例子。
Plant mitochondrial transcripts undergo maturation processes at both termini. Although frequently observed, the post‐transcriptional formation of mature 5′ ends is still poorly understood. We now analyzed the processing of transcripts derived from the mitochondrialccmCgene, coding for a component of the cytochromecmaturation system. InArabidopsis thaliana(Arabidopsis) there are two mitochondrialccmCconfigurations, discriminated by a 66‐bp sequence segment located approximately 500 bp upstream of theccmCgene. In Arabidopsis accessions these divergent mitochondrial genotypes correlate with the generation of two different 5′ termini that map to positions around −484 in accession Columbia (ColccmCgenotype) or −390 in accession C24 relative to the translation start codon (C24ccmCgenotype). Previously we identified RNA PROCESSING FACTOR 3 (RPF3), a pentatricopeptide repeat (PPR) protein required for the maturation ofccmCmRNAs with −484 5′ ends transcribed from the ColccmCgenotype. Now we identified several accessions defective in maturation ofccmCtranscripts. Taking advantage of this natural genetic variation we identified RNA PROCESSING FACTOR 6 (RPF6), a PPR protein necessary for the generation ofccmCmRNAs with −390 5′ ends transcribed from the C24ccmCgenotype. Both Col‐type and C24‐type accessions encode RPF3 and RPF6 so that they can processccmCtranscripts derived from the two different mitochondrial genotypes. These factors and their cognate RNA recognition sites in the differentccmCgenotypes are an intriguing example for the evolution of two co‐adapted cyto‐nuclear systems required for the same process i.e. 5′ maturation ofccmCtranscripts.
