[Genomic context of nucleus influences mitochondrial gene expression of HL-type rice].
In eukaryotic cells, the role of mitochondria is to generate both ATP and carbon skeletons for biosynthetic purposes. Meanwhile, the mitochondrial genes, in plant, are also involved in the development of anther. The presence of genetic information within mitochondria and nucleus make intracellular cooperation necessary. In this paper, a new RAPD method is used to analyze the expression differences of rice mitochondrial gene with the change of nuclear background. Many different fragments are obtained from hybrids, but not from sterile line or remainder line. According to the results, it is concluded that there are extensive effects of nuclear background on mitochondrial gene expression.
