Abstract

Abstract Restriction fragment length polymorphism (RFLP) was used to analyze mitochondrial (mt) genome of cytoplasmic male sterility (CMS) rice. Differences were observed among mitochondrial genomes of the sterile line (A) and maintain line (B) of nine types of CMS rice; Mitochondrial genomic differences were also detected between A and B in many functional gene regions. Even the materials with the same nucleic background have differences in their mtDNA. This provides molecular evidence for the cytoplasmic heterogeneity and the CMS mechanism research.
