Gene Details:

• MSU gene ID: LOC_Os10g38050
• RAPdb gene ID: Os10g0524500
• Gene Symbol: OsTMS18
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Further analysis showed that the tapetal transcription factor OsMS188 directly regulates OsTMS18 for pollen wall formation.
• Cellular analysis revealed the pollen wall of OsTMS18 to be defective, leading to aborted pollen under high temperature.
• Under low temperature, the flawed pollen wall in OsTMS18 is sufficient to protect its microspore, allowing for development of functional pollen and restoring fertility.
• OsTMS18 sterility is more stable in summer than the TGMS line carrying the widely used locus tms5 in the ZH11 genetic background, suggesting its potential application for rice breeding.
• The OsTMS18 TGMS trait is caused by the point mutation from Gly to Ser in a glucose-methanol-choline (GMC) oxidoreductase; knockout of the oxidoreductase was previously reported to cause complete male sterility.
