Identification and characterization of MADS-box gene family in flax, Linum usitatissimum L. and its role under abiotic stress
Bibliographic record
Abstract
Summary MADS-box transcription factors play critical roles in plant development and stress responses. In this study, we identified 114 LuMADS genes in flax (Linum usitatissimum L.) and analyzed their phylogenetic relationships, gene structure, conserved motifs, miRNA targets, and expression patterns. We classified 45 LuMADS proteins as type I and 69 as type II, further subdivided into 11 subfamilies. Notably, lus-miR396 and lus-miR156 were identified as primary miRNA targets. Cis-acting elements in the promoter regions suggested roles in hormone and stress responses. Expression analysis revealed type II LuMADS genes were associated with floral organ formation and abiotic stresses such as cold, drought, and salt. This research provides insights for improving flax stress resistance and breeding.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
