Dynamic DNA Methylation Landscapes in Maize Roots Under Salt Stress
Bibliographic record
Abstract
Salt stress is one of the main abiotic factors limiting the yield of maize ( Zea mays L.), especially having a significant impact on root growth, water absorption and ion homeostasis. Recent studies have shown that epigenetic regulatory mechanisms, especially DNA methylation, play a significant role in plants’ response to adverse stress. However, there is still a lack of systematic research on the dynamic changes of the whole-genome DNA methylation map of maize roots under salt stress conditions. This study reviews the physiological and molecular response characteristics of maize root systems under salt stress, as well as the biological functions of DNA methylation in plant stress responses. It introduces the types of methylation and their detection techniques, analyzes in detail the dynamic change characteristics and functional enrichment pathways of methylation profiles under salt stress, and compares the methylation differences between typical salt-tolerant and sensitive maize varieties. It reveals the possible mechanism of epigenetic regulation in the formation of salt tolerance. This study explored the dynamic regulatory mechanism of DNA methylation in maize roots under salt stress, providing a new perspective for a deeper understanding of plant epigenetic responses and also offering a theoretical basis and data support for the development of salt-tolerant maize varieties.

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.
