Cloning and characterization of two glutathione <i>S</i>‐transferase cDNAs in the spruce budworm, <i>Choristoneura fumiferana</i>
Bibliographic record
Abstract
Two Choristoneura fumiferana glutathione S-transferase cDNAs were cloned from a cDNA library constructed using mRNA from the midgut cell line, CF-203. These cDNAs (CfGST2, CfGST3) encoded two structurally different proteins with a predicted molecular mass of 21 and 24 kDa, respectively, which was confirmed through protein expression in a bacterial system. Quantitative reverse-transcription PCR analyses revealed that the transcripts of these two genes were present in the epidermis, fat body, and midgut of the 6th instar larvae. CfGST2 was expressed in the fat body when the insects were close to pupal molting, while it was constantly expressed in the other two tissues during the 6th instar stage. CfGST3 gene was expressed highly and constantly in all of the tissues throughout the 6th instar stage. Immunohistochemistry analysis demonstrated that CfGST2 and CfGST3 proteins were present mainly in the fat body and epidermis and no protein was detected in the midgut. CfGST2 and CfGST3 were different from CfGST reported before (Feng et al., 1999: Insect Biochem Mol Biol 29:779-793) in amino acid sequence, expression pattern, and responsiveness to tebufenozide.

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.
