Stacking of Multiple Resistance Genes in Wheat via Transgenic Approaches
Bibliographic record
Abstract
Wheat diseases continue to threaten global food security, leading to yield losses and reduced grain quality. Consequently, effective and sustainable disease resistance strategies are urgently needed. This study explores the stacking of multiple resistance genes in wheat through transgenic approaches as a promising solution to these challenges. We first outline the principles of gene stacking, including the necessity to overcome pathogen evolution, ensure broad and durable resistance, and meet environmental and agricultural needs. We then discuss various transgenic strategies, such as direct genetic transformation, synthetic multigene constructs, and CRISPR/Cas-mediated genome editing, highlighting their potential for assembling and integrating multiple resistance genes. We also detail specific resistance genes commonly used in transgenic wheat, including those targeting rusts (e.g., Lr34, Sr22, Yr36), fungal and viral pathogens, and genes involved in broad-spectrum defense (e.g., pathogenesis-related proteins). Using the case study of transgenic stacking for rust resistance, specifically against Ug99 rust, we illustrate the practical applicability and global impact of this approach. We also explore the technical challenges, biosafety regulations, and genetic complexity that hinder its implementation. Looking ahead, we explore innovations in synthetic biology, precision gene editing, and breeding for climate resilience. Finally, we summarize recent advances in gene stacking, identify key gaps, and highlight the future potential of transgenic technology for enhancing durable disease resistance in wheat.

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.
