Abstract

fetched live from OpenAlex

Trypsin inhibitors (TIs) in soybean are known to have antinutritional effects, reducing protein digestibility and limiting the nutritional value of soy products and animal feeds. To address this long-standing challenge, genome editing tools such as CRISPR/Cas9 have emerged as promising strategies for precisely eliminating undesirable traits such as TIs. This study explores the application of CRISPR/Cas9 to targetedly ablate trypsin inhibitor genes in soybean, specifically those encoding Kunitz and Bowman-Birk inhibitors. We discuss the biological functions and limitations of these inhibitors, outline the mechanisms and recent technical improvements of CRISPR/Cas9, and detail methods for identifying TI gene targets using transcriptomic and proteomic analyses. We also review guide RNA design, translational techniques, and gene editing validation. Functional assessments demonstrated that knockout lines exhibited reduced TI activity, improved protein digestibility, and improved nutritional status, with minimal adverse effects on agronomic traits. A case study demonstrating the successful ablation of the Kunitz trypsin inhibitor gene further demonstrates the utility of this approach. We also explore biosafety concerns, regulatory frameworks, and public perception issues surrounding genome-edited crops. Ultimately, this study highlights the transformative potential of CRISPR/Cas9 for improving the nutritional quality of soybeans and supports future efforts to integrate genome editing into breeding programs to develop high-protein, low-antinutrient varieties.

Teacher imitation

Not 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.
