Gene Details:

• MSU gene ID: LOC_Os07g35610
• RAPdb gene ID: Os07g0540366
• Gene Symbol: DTC1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Mutants defective in DTC1 exhibit phenotypes of an enlarged tapetum and middle layer with delayed degeneration, causing male sterility.
• Whereas wild-type plants accumulate large amounts of ROS in their anthers at Stage 9 of development, those levels remain low during all stages of development in DTC1 anthers.
• These results suggest that DTC1 functions downstream of those transcription factor genes and upstream of the genes encoding secretory proteins.
• These findings indicate that DTC1 is a key regulator for tapetum PCD by inhibiting ROS-scavenging activity.
• In DTC1 anthers, expression of genes encoding secretory proteases or lipid transporters is significantly reduced, while transcripts of PCD regulatory genes, e.
