- Ability of Rf5 and Rf6 to Restore Fertility of Chinsurah Boro II-type Cytoplasmic Male Sterile Oryza Sativa (ssp. Japonica) Lines.
- The BT-type F(1) hybrids with either Rf5 or Rf6 exhibited normal seed setting rates, but F(1) plants carrying Rf6 showed more stable seed setting rates than those of plants carrying Rf5 under heat-stress conditions
- Furthermore, the seed setting rates of F(1) hybrids carrying both Rf5 and Rf6 were more stable than that of F(1) plants carrying only one Rf gene
- CONCLUSION: Rf6 is an important genetic resource for the breeding of BT-type japonica restorer lines
- RF6 is targeted to mitochondria, where it physically associates with hexokinase 6 (OsHXK6) and promotes the processing of the aberrant CMS-associated transcript atp6-orfH79 at nucleotide 1238, which ensures normal pollen development and restores fertility
- The duplicated motif 3 of RF6 is essential for RF6-OsHXK6 interactions, processing of the aberrant transcript, and restoration of fertility
- Together these results reveal a novel mechanism for CMS restoration by which RF6 functions with OsHXK6 to restore HL-CMS fertility
- The HL-CMS trait is associated with an aberrant chimeric mitochondrial transcript, atp6-orfH79, which causes pollen sterility and can be rescued by two nonallelic restorer-of-fertility (Rf) genes, Rf5 or Rf6
- Pentatricopeptide-repeat family protein RF6 functions with hexokinase 6 to rescue rice cytoplasmic male sterility.
