Adding N to Water-Stressed Sorghum bicolor Shifts Root Functional Traits and Uptake Strategies, but Without Short-Term Improvements in Water Use Efficiency or Productivity.

Abstract excerpt

Given the co-limitation of water and nitrogen (N) acquisition under drought, it is essential to mechanistically explore how plants respond to these limitations individually and in combination. To understand the general effect that N availability plays in water use efficiency across Sorghum bicolor ssp. bicolor, which has diverse mechanisms conferring tolerance to water limitations, we grew six genotypes ranging...
