Sorting out the<i>LeMAN</i>s: endo-β-mannanase genes and their encoded proteins in tomato
Bibliographic record
Abstract
Abstract Endo-β-mannanase (EC 3.2.1.78) is involved in the hydrolysis of mannan-type polysaccharides that are present in plant cell walls, especially those of the seed endosperm. The genes encoding the endo-β-mannanases have been studied extensively in tomato ( Solanum lycopersicum ), and five genes ( LeMAN1 , LeMAN2 , LeMAN3 , LeMAN4 and LeMAN5 ) and/or their products have been isolated and characterized. LeMAN1 , LeMAN2 and LeMAN3 are expressed in tomato seeds, LeMAN4 in the fruit and LeMAN5 in the flower. LeMAN5 and LeMAN2 are now considered to be the same gene, and the former is re-designated as LeMAN2* . Transcripts of LeMAN s 1, 2 and 3 are detected only in the endosperm of tomato seeds, and their synthesis is promoted by gibberellic acid. LeMAN4 , in the fruit, occurs as LeMAN4a and LeMAN4i genes that encode an active or inactive form of endo-β-mannanase, respectively. Le MAN1–4 enzymes encoded by these genes share 80% similarity in amino acid sequence. In tomato, the leucine amino acid present near to the C-terminus of the endo-β-mannanase is the most important for achieving full activity of the enzyme.

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.
