Abstract
Fragrance is one of the most important quality traits for breeding in rice. The natural aroma substance 2-acetyl-1-pyrroline (2-AP) is a key fragrance compound among over 200 volatiles identified in fragrant rice. In addition to rice, there are other plant species that contain a germplasm that naturally produces a fragrant aroma. These other plant species all have lower activity levels of the enzyme BETAINE ALDEHYDE DEHYDROGENASE 2 (BADH2). Therefore, improving fragrance efficiency has been a focus of intensive research. Recent studies have engineered BADH2 gene, which is responsible for fragrance trait in non-fragrant cultivars of rice, using CRISPR-Cas9. Although engineering rice BADH2 can be useful for upregulating 2-AP, there are still a lot of restrictions on how it can be applied in practice. In this review article, we discuss the recent developments in BADH2 editing and propose potential future strategies to effectively target BADH2 for transcriptional regulation, with the goal of producing a better fragrance.

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 it
