- RAPdb: Os01g0578500
- Publication
- Hybrid male sterility in rice controlled by interaction between divergent alleles of two adjacent genes, 2008, Proc Natl Acad Sci U S A.
- Suppression or knockout of SaF/SaM overcomes the Sa-mediated hybrid male sterility in rice., 2017, J Integr Plant Biol.
- Genbank accession number
- Key message
- Here we show that a locus for indica-japonica hybrid male sterility, Sa, comprises two adjacent genes, SaM and SaF, encoding a small ubiquitin-like modifier E3 ligase-like protein and an F-box protein, respectively
- This allele-specific gamete elimination results from a selective interaction of SaF(+) with SaM(-), a truncated protein, but not with SaM(+) because of the presence of an inhibitory domain, although SaM(+) is required for this male sterility
- The complex locus Sa comprises two adjacently located genes, SaF and SaM, which interact to cause abortion of pollen grains carrying the japonica allele in japonica-indica hybrids
- Our results firmly proved that SaF and SaM are required for the hybrid male sterility, but are not essential for pollen development
- Here we showed that silencing of SaF or SaM by RNA interference restored male fertility in indica-japonica hybrids with heterozygous Sa
