Summation

GW2 encodes a RING-type E3 ubiquitin ligase. Loss of GW2 function cause increase in cell numbers, resulting in a larger (wider) spikelet hull, and acceleration the grain milk filling rate, resulting in enhanced grain width, weight and yield. OsGW2 negatively regulates cell division by targeting its substrate(s) to proteasomes for regulated proteolysis (Song et al., 2007). Overexpression of OsGW2 causes restriction of cell proliferation, resulting in development of lighter grains (Song et al., 2007).
