- ... Deposition of ammonium (NH₄ ⁺) from the atmosphere is a substantial environmental problem. While toxicity resulting from root exposure to NH₄ ⁺ is well studied, little is known about how shoot-supplied ammonium (SSA) affects root growth. In this study, we show that SSA significantly affects lateral root (LR) development. We show that SSA inhibits lateral root primordium (LRP) emergence, but not LR ...
