• Information
  • Symbol: Rf17,RMS
  • MSU: LOC_Os04g40020
  • RAPdb: Os04g0475900
• Publication
  • Suppressed expression of Retrograde-Regulated Male Sterility restores pollen fertility in cytoplasmic male sterile rice plants, 2009, Proc Natl Acad Sci U S A.
• Genbank accession number
  • AB481199
• Key message
  • RMS encodes a mitochondrial protein, 178 aa in length, of unknown function, unlike the majority of other Rf genes cloned thus far, which encode pentatricopeptide repeat proteins
  • Through positional cloning, we identified a nuclear candidate gene, RETROGRADE-REGULATED MALE STERILITY (RMS) for Rf17, a fertility restorer gene for Chinese wild rice (CW)-type CMS in rice (Oryza sativa L
  • RNA interference-mediated gene silencing of RMS restored fertility to a CMS plant, whereas its overexpression in the fertility restorer line induced pollen abortion
  • We found that a reduced-expression allele of the RMS gene restored fertility in haploid pollen, whereas a normal-expression allele caused pollen to die in the CW-type CMS
  • The mRNA expression level of RMS in mature anthers depended on cytoplasmic genotype, suggesting that RMS is a candidate gene to be regulated via retrograde signaling
