The bacteriophage λ rex-centric mutualism phenotype, conditional rex, and other novel rex phenotypes
Bibliographic record
Abstract
XVllT4rll plaque morphology on A Iysogens carrying the multicopy constitutive rexA+ plasmid.Our results suggest that an induced Cro+ A prophage escapes Rex exclusion by over-expressing rexB relative to rexA, while a derepressed Acroprophage suppresses Rex exclusion phenotype by over-expressing rexA relative to rexB. CI Repressor Modulation of the Rex Exclusion PhenotypeBacteriophage A mutants defective for ren and red (exo or bet) are sensitive to restriction by A rex genes, but exclusion is modulated by the c/ repressor allele of the prophage.Aspi 156nin5 forms plaques with 10 5 fold higher efficiency on a ct-lysogen than on c/[Ts]857, or c/[Ts]2 derivatives.Exclusion in c/[Ts] Iysogens is suppressed by complementation with ct plasmid.

How this classification was reachedexpand
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.
