Diet-dependent regulation of labial salivary genes in the beet armyworm, «Spodoptera exigua»
Bibliographic record
Abstract
The beet armyworm, Spodoptera exigua, has evolved numerous mechanisms to circumvent plant defense responses. One of these mechanisms is believed to involve the activity of labial salivary glucose oxidase (GOX) which, through the production of hydrogen peroxide, interferes with plant induced defenses. The activity of GOX is diet-dependent. The expression of SeGox and another salivary gene, Se1H, are differentially regulated in response to diet (plant or transfer from plant to wheat-germ based artificial diet for 4 hours), but not in response to chemically defined artificial diets varying in protein to digestible carbohydrate ratios. However, GOX enzyme activity is dependent on the nutrient quality of the chemically defined artificial diets. This suggests that nutritional quality controls enzyme activity through post-transcriptional regulation. To simulate natural plant diets, Medicago truncatula plants were grown under ambient (440 ppm) or elevated (880 ppm) carbon dioxide conditions to alter their C:N ratio. When caterpillars were fed these plants, labial salivary GOX activity was undetectable regardless of the plant treatment. Finally, 5' upstream regions of salivary genes Se1H, Se2J and SeGox were amplified to determine potential upstream promoter elements, but were unable to be sequenced due to amplicon contamination.

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.
