Exploiting a genetic quirk in potatoes may cut fertilizer needs
A gene that controls when potato plants form their tubers also limits nitrogen uptake
Genetically modified plants with the silenced StCDF1 gene (right) fared much better in low-nitrogen conditions than control plants (left) and plants with an overexpressed StCDF1 gene (center and center-left), showing that StCDF1 limits nitrogen uptake.
