To test the hypothesis that multiple integrated root phenotypes would co-optimize drought tolerance, we phenotyped the root anatomy and architecture of 400 mature maize ( ) genotypes under well-watered and water-stressed conditions in the field. We found substantial variation in all 23 root phenes m...
