Gene Details:

• MSU gene ID: LOC_Os08g37890
• RAPdb gene ID: Os08g0485500
• Gene Symbol: AL8 RAE2 GAD1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Our findings illuminate the molecular function of RAE2 in awn development and shed light on the independent domestication histories of Asian and African cultivated rice.
• The RAE2 precursor is specifically cleaved by SLP1 in the rice spikelet, where the mature RAE2 peptide subsequently induces awn elongation.
• GAD1 Encodes a Secreted Peptide That Regulates Grain Number, Grain Length and Awn Development in Rice Domestication.
• A frame-shift insertion in GAD1 destroyed the conserved cysteine residues of the peptide, resulting in a loss of function, and causing the increased number of grains per panicle, shorter grains and awnless phenotype characteristic of cultivated rice.
