Abstract: In recent years， the new advances correlated with cytoplasmic male sterility (CMS) in the fields of cytology， biochemistry and molecular genetics， have been achieved. Especially in the cloning and identification of the restorer genes， great progress had been made. It indicates that some genes that encode proteins which have conservative pentatricopeptide repeat (PPR) motif are closely associated with fertility restoration in some CMS plants. In this paper， the recent advances all above are reviewed and the future research direction of it also discussed.
