Plasticity of maize (<i>Zea mays</i> L.) roots in water‐deficient and nitrogen‐limited soil
Bibliographic record
Abstract
Abstract Maize ( Zea mays L.), a versatile global crop with diverse application in food, feed, and industry, experiences production challenges due to water deficits and concurrent nitrogen (N) limitations. Maize relies on multiple root types, including primary, seminal, crown, brace roots, and associated lateral roots, to acquire water and nutrients from the soil. These root types exhibit distinct soil water and N uptake capacities, dynamically adjusting their morphological and anatomical traits to optimize resource uptake. This review summarizes the plastic responses of maize roots to soil water deficit, N limitation, and lack of other essential nutrients. In response to water deficit, maize axial roots bend toward regions with higher water availability and produce more lateral roots. Simultaneously, the diameter of the root xylem decreases, facilitating sustained water uptake from dry soil. In response to N limitation, maize increases lateral root length, reduces xylem area, and increases cortical aerenchyma. This review enhances our understanding of maize root adaptability in water‐limited and N‐poor soils, offering valuable perspectives on optimizing root growth for improved water and N acquisition.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
