Gene Details:

• MSU gene ID: LOC_Os01g34350
• RAPdb gene ID: Os01g0527600
• Gene Symbol: OsRDR6 shl-2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• We isolated a rice OsRDR6-1 mutant, which was temperature sensitive and showed spikelet defects.
• In three independent transgenic lines (OsRDR6AS line A, B and C) in which OsRDR6 transcription levels were reduced by 70-80% through antisense silencing, the infection and disease symptoms of RSV were shown to be significantly enhanced.
• The hypersusceptibilities of the OsRDR6AS plants were attributed not to enhanced insect infestation but to enhanced virus infection.
• We propose that ABA modulates PTGS through the transcriptional control of the OsRDR6 gene.
• OsRDR6 plays role in host defense against double-stranded RNA virus, Rice Dwarf Phytoreovirus.
