DEP1 is involved in regulating the carbon-nitrogen metabolic balance to affect grain yield and quality in rice (Oriza sativa L.).
The DEP1 (dense and erect panicle 1) gene, which corresponds to the erect panicle architecture, shows a pleiotropic effect in increasing grain yield and nitrogen use efficiency (NUE) in rice.Nevertheless, it remains unclear whether the carbon-nitrogen metabolic balance changes as the dep1 allele enhances nitrogen uptake and assimilation.In this stu
