Ammonium Triggers Lateral Root Branching in Arabidopsis in an AMMONIUM TRANSPORTER1;3-Dependent Manner[W]

摘要

This study identifies that local ammonium supply triggers lateral root branching in Arabidopsis preferentially in the presence of AMT1;3. Ammonium thereby shapes lateral root architecture in a complementary manner to nitrate, which preferentially promotes lateral root elongation.
