摘要
Dear Editor, Grain length （size） and weight are essential components of crop yield. To date, many QTLs/genes for these traits have been identified. GS3 encodes a putative transmembrane protein and functions as a negative regulator, and its larger-grain allele contains a nonsense mutation causing a 178-aa truncation （Fan et al., 2006）. GL3.1/qGL3 encodes a putative protein phosphatase and also acts as a negative regulator of grain size （Qi et al., 2012; Zhang et al., 2012）. Another negative regulator of grain size and weight is TGW6, which hydrolyzes indole-3-acetic acid （IAA）-glucose into IAA and glucose （Ishimaru et al., 2013）.
