Understanding the molecular genetic mechanisms governing agronomic traits such as grain yield is important for genetics as well as agriculture. A newly discovered quantitative trait locus, GW2, which encodes a new RING-type E3 ubiquitin ligase, has been found to regulate rice grain width. This insight should prove useful for improving the yield of staple grains.
