The root hairless mutant buzz in Brachypodium distachyon shows increased nitrate uptake and signaling but does not affect overall nitrogen use efficiency.

Abstract excerpt

Root systems are uniquely adapted to fluctuations in external nutrient availability. In response to suboptimal nitrogen conditions, plants adopt a root foraging strategy that favors a deeper and more branched root architecture, enabling them to explore and acquire soil resources. This response is gradually suppressed as nitrogen conditions improve. However, the root hairless mutant buzz in Brachypodium distachyon...
