Figure 2 : Seed shattering in wild rice and cultivated rice

Caption

A. Comparison of the panicles of wild rice and cultivated rice: When wild rice seeds ripen, seed shattering occurs in which they naturally fall to the ground. B. Comparison of the seed bases between wild rice and cultivated rice: Seed shattering is caused by the breakdown of the abscission layer that forms at the base of the seed. C. Comparison of the structural positioning of the abscission layer in wild rice and cultivated rice: In wild rice, abscission layers are fully formed around the vascular bundles. However, in cultivated rice (japonica), the abscission layer isn’t formed at all.
