Low nitrogen availability inhibits the phosphorus starvation response in maize (Zea mays ssp. mays L.).

ABSTRACT:

Background

Nitrogen (N) and phosphorus (P) are macronutrients essential for crop growth and productivity. In cultivated fields, N and P levels are rarely sufficient, contributing to the gap between realized and potential production. Fertilizer application increases nutrient availability, but is not available to all farmers, nor are current rates of application sustainable or environmentally desirable. Transcriptomic studies of cereal crops have revealed dramatic responses to either low N or low P single stress treatments. In the field, however, levels of both N and P may be suboptimal. The interaction between N and P starvation responses remains to be fully characterized.

Results

We characterized growth and root and leaf transcriptomes of young maize plants under nutrient re
