Gene Details:

• MSU gene ID: LOC_Os01g39680
• RAPdb gene ID: Os01g0578700
• Gene Symbol: SaM
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Male semi-sterility in this heterozygous complex locus is caused by abortion of pollen carrying SaM(-).
• 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.
• 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.
