Abstract
This study systematically analyzes recent research progress on the pineapple (Ananas comosus) genome, focusing on three key evolutionary features: the transition from C3 to CAM photosynthesis, chromosomal rearrangements, and the evolution of gene duplication clusters. Major findings indicate that during its evolutionary history, pineapple underwent limited whole-genome duplication events, retained a relatively conserved karyotype of seven chromosomes, and achieved functional gene expansion and diversification through segmental duplications and chromosomal structural rearrangements. By constructing an integrated framework of pineapple genome evolution, this study provides both theoretical foundations and practical guidance for future research on monocot evolution and the molecular breeding of crops with enhanced stress tolerance traits.

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
