Gene Details:

• MSU gene ID: LOC_Os09g10850
• RAPdb gene ID: Os09g0280600
• Gene Symbol: OsMFS1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Taken together, our results indicated that OsMFS1 is indispensable to the normal development of anther and embryo sacs in rice.
• Here, we characterized a completely sterile OsMFS1 (male and female sterility 1) mutant which has its pollen and embryo sacs both aborted at the reproductive stage due to severe chromosome defection.
• Map-based cloning revealed that the OsMFS1 encodes a meiotic coiled-coil protein, and it is responsible for DSB repairing that acts as an important cofactor to stimulate the single strand invasion.
• Subcellular localization analysis of OsMFS1 revealed its association with the nucleus exclusively.
• Expression pattern analyses showed the OsMFS1 was preferentially expressed in meiosis stage.
• In addition, a yeast two-hybrid (Y2H) and pull-down assay showed that OsMFS1 could physically interact with OsHOP2 protein to form a stable complex to ensure faithful homologous recombination.
