高等植物线粒体的遗传因子要比动物和真菌的大而复杂。近期的研究工作证实,这种复杂性的部分原因在于其分子内重组。在重组中,由一主基因环繁衍形成—亚基因环群体。部分高等植物的线粒体基因,有的已完全序列化。另一方面,有关甜菜线粒体基因组的资料表明,这种序 Higher plant mitochondrial genetic factors than animal and fungal large and complex. Recent research has confirmed that part of this complexity is due to its intramolecular recombination. In the reorganization, a major gene loop multiply formed - sub-ring group. Some higher plants mitochondrial genes, and some have been completely serialized. On the other hand, data on the mitochondrial genome of sugar beets suggest that this sequence
