Gene Details:

• MSU gene ID: LOC_Os09g36190
• RAPdb gene ID: Os09g0531900
• Gene Symbol: OsPDT1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The OsPDT1 mutant exhibited premature programmed cell death (PCD) of the tapetum and disordered pollen walls, resulting in aborted pollen grains.
• Pectin distribution in the anther sac was comparable between the mutant and the wild-type, suggesting that the structural pectin was not dramatically affected in OsPDT1.
• These results suggest that the mutation of OsPDT1 does not dramatically affect structural pectin but affects components of the pectin-mediated signaling pathway, such as OsiWAK1, and causes male sterility.
• OsiWAK1 RNA interference lines exhibited earlier tapetal PCD, similar to OsPDT1.
