Molecular mapping of the <i>chlorophyll retainer</i> (<i>cl</i>) mutation in pepper (<i>Capsicum</i> spp.) and screening for candidate genes using tomato ESTs homologous to structural genes of the chlorophyll catabolism pathway
Bibliographic record
Abstract
The chlorophyll retainer (cl) mutation causes inhibition of chlorophyll degradation during pepper fruit ripening and is controlled by a single recessive gene. The retention of chlorophyll in mature red or yellow fruits produces brown- or green-colored ripe fruits, respectively. We mapped CL on chromosome 1 of pepper corresponding to chromosome 8 in tomato in which a homologous mutation, green flesh, was previously assigned. To test whether known structural genes from the chlorophyll catabolism pathway could correspond to CL, we mapped tomato expressed sequence tag clones corresponding to three loci of CHLOROPHYLLASE and one locus of PHEOPHORBIDE A OXYGENASE in the tomato introgression lines population. The three CHLOROPHYLLASE loci mapped to chromosomes 6, 9, and 12, while PHEOPHORBIDE A OXYGENASE mapped to chromosome 11, indicating that CL may correspond to an as yet unavailable gene from the chlorophyll catabolism pathway or to a regulator of the pathway.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
