The rice HGW gene encodes a ubiquitin-associated (UBA) domain protein that regulates heading date and grain weight.

Heading date and grain weight are two determining agronomic traits of crop yield. To date, molecular factors controlling both heading date and grain weight have not been identified. Here we report the isolation of a hemizygous mutation, heading and grain weight (hgw), which delays heading and reduce...
