Gene Details:

• MSU gene ID: LOC_Os04g55560
• RAPdb gene ID: Os04g0649100
• Gene Symbol: SHAT1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The SHAT1 gene, which encodes an APETALA2 transcription factor, is required for seed shattering through specifying abscission zone (AZ) development in rice.
• Genetic analyses revealed that the expression of SHAT1 in AZ was positively regulated by the trihelix transcription factor SH4.
• Here, we identified a seed shattering abortion1 (SHAT1) mutant in a wild rice introgression line.
• Our results suggest a genetic model in which the persistent and concentrated expression of active SHAT1 and SH4 in the AZ during early spikelet developmental stages is required for conferring AZ identification.
