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 ...

However even with this partial abscission layer junction, the seeds still tend to fall easily in a natural environment. Credit Ishikawa et al. (2022) PNAS Plant Breeding Lab. Graduate School of ...

A normal fruiting head (Fig. 1) contains 4–10 seeds and is shed from the parent plant, as the seeds ripen, by the development of an abscission layer. The seeds are retained within the cortical ...

New research suggests that the historical emergence of cultivated rice from wild rice plants resulted from a combination of three gene mutations that make the seeds (i.e., the grains of rice ...
