Annotated Information
Gene Symbol
- Os10g0499500 <=> RF1b, Rf-1B, PPR7
Function
- Two fertility restorer genes, Rf1a and Rf1b, were identified at the classical locus Rf-1 as members of a multigene cluster that encode pentatricopeptide repeat proteins. RF1A and RF1B are both targeted to mitochondria and can restore male fertility by blocking ORF79 production via endonucleolytic cleavage (RF1A) or degradation (RF1B) of dicistronic B-atp6/orf79 mRNA.
- Rf1a and Rf1b function independently to restore male fertility by silencing the CMS gene via different RNA processing pathways.
