自然遗传变异影响模式物种拟南芥(拟南芥)的发育、生理、生化特性以及线粒体转录本。在之前的研究中,我们鉴定了拟南芥属植物Columbia、C24和Landsbergerecta的线粒体转录末端多态性。多态转录物种可能是由于线粒体DNA的差异,也可能是由于细胞核的自然遗传变异。为了分析分布并确定额外的5 '端多态性,我们现在分析了26个不同材料中的19个线粒体转录单位。我们发现了额外的5 '端多态性,表明这种转录物长度差异在拟南芥中是一种普遍现象。新的多态性影响cox1,cox2,nad2以及nad3-rps12转录物种。虽然氧化酶2多态性可归因于线粒体DNA的重组事件,但氧化酶2转录本多态性与核DNA的差异有关。在nad3- rps12mrna中发现了一个复杂的模式,其5 '端在几个加入中不同。这些新的多态性为更详细地表征线粒体5 '端加工提供了重要的基础。
Natural genetic variation affects development, physiology, biochemical properties as well as mitochondrial transcripts of the model speciesArabidopsis thaliana(Arabidopsis). In a previous study, we identified mitochondrial transcript end polymorphisms inArabidopsisaccessions Columbia, C24 and Landsbergerecta. The polymorphic transcript species could either be assigned to differences in the mitochondrial DNA or to natural genetic variation in the nucleus. To analyze the distribution and to identify additional 5′ end polymorphisms we now analyzed 19 mitochondrial transcription units in 26 different accessions. We found additional 5′ end polymorphisms indicating that such transcript length differences are a widespread phenomenon inArabidopsis. The new polymorphisms affectcox1,cox2,nad2as wellnad3-rps12transcript species. While thecox2polymorphism can be attributed to a recombination event in the mitochondrial DNA, thenad2transcript polymorphism is linked to differences in the nuclear DNA. A complex pattern is found fornad3-rps12mRNA whose 5′ ends differ between several accessions. These new polymorphisms provide an important basis for a more detailed characterization of mitochondrial 5′ end processing.
