Abstract
Abstract Sugarcane is an important crop worldwide, and most sugar is derived directly from sugarcane. Due to its thermophilic nature, the yield of sugarcane is largely influenced by extreme climate conditions, especially cold stress. Therefore, the development of sugarcane with improved cold tolerance is an important goal. However, little is known about the multiple mechanisms underlying cold acclimation at the bud stage in sugarcane. In this study, we emphasized that sensitivity to cold stress was higher for the sugarcane variety ROC22 than for GT42, as determined by physical signs, including bud growth capacity, relative conductivity, malonaldehyde contents, and soluble sugar contents. To understand the factors contributing to the difference in cold tolerance between ROC22 and GT42, comparative transcriptome analyses were performed. We found that genes involved in the regulation of the stability of the membrane system were the relative determinants of difference in cold tolerance. Additionally, genes related to protein kinase activity, starch metabolism, and calcium signal transduction were associated with cold tolerance. Finally, 25 candidate genes, including 23 variety-specific and 2 common genes, and 7 transcription factors were screened out for understanding the possible cold resistance mechanism. The findings of this study provide candidate gene resources for cold resistance and will improve our understanding of the regulation of cold tolerance at the bud stage in sugarcane.

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
