A candidate factor that interacts with RF2 a restorer of fertility of Lead rice-type cytoplasmic male sterility in rice

摘要

BackgroundThe pollen function of cytoplasmic male sterile (CMS) plants is often recovered by the Restorer of fertility (Rf) gene encoded by the nuclear genome. An Rf gene of Lead rice type CMS, Rf2, encodes a small mitochondrial glycine-rich protein. RF2 is expected to function by interacting with other proteins, because RF2 has no motifs except for glycine-rich domain.
