| Research Abstract |
We studied a mechanism of cytoplasmic male sterility (CMS) /fertility restoration (RF) system, that is useful for hybrid rice breeding. We demonstrated accumulation of ORF79 peptide is a cause of LD-type CMS. We identified several possible components of RF complex of RF2, which is a RF factor for LD-type CMS. We proposed a model in which a RNA-binding glycine-rich protein, GRP162, and a mitochondrial ribonuclease are candidate factors of RF2 complex to degrade atp6-orf79 RNA.
