Internal ammonium excess induces ROS-mediated reactions and causes carbon scarcity in rice.

ABSTRACT:

Background

Overuse of nitrogen fertilizers is often a major practice to ensure sufficient nitrogen demand of high-yielding rice, leading to persistent NH₄⁺ excess in the plant. However, this excessive portion of nitrogen nutrient does not correspond to further increase in grain yields. For finding out the main constraints related to this phenomenon, the performance of NH₄⁺ excess in rice plant needs to be clearly addressed beyond the well-defined root growth adjustment. The present work isolates an acute NH₄⁺ excess condition in rice plant from causing any measurable growth change and analyses the initial performance of such internal NH₄⁺ excess.

Results

We demonstrate that the acute inte
