Abstract excerpt

Grain chalkiness is a detrimental trait that significantly reduces the quality and economic value of rice, yet its regulatory mechanisms remain poorly understood. To identify genetic loci regulating grain chalkiness, we performed high-throughput activation tagging-based T-DNA insertion mutagenesis in the model rice variety (Oryza sativa L.) Kitaake. We found that a loss-of-function mutation in OsMADS18 resulted...
