Abstract
A full-length cDNA encoding a general odorant binding protein 2 (GOBP2) was cloned from the antennae of the rice striped stem borer, Chilo suppressalis (Lepidoptera: Pyralidae), by the combination of reverse transcription PCR (RT-PCR) and rapid amplification of cDNA ends PCR (RACE-PCR). The cDNA contains a 489 bp open reading frame, which encodes a 162 amino acid protein, termed as Ch. suppressalis GOBP2 (CsupGOBP2). CsupGOBP2 is similar in the number of amino acids and protein sequence to GOBP2s in other species of Lepidoptera. RT-PCR results showed that CsupGOBP2 mRNA was highly expressed in the adult antennae of both females and males, as was CsupGOBP2 protein as revealed by Western blot analysis. CsupGOBP2 expressed in Escherichia coli was purified by affinity chromatography, refolding and gel filtration from the inclusion body. Fluorescence emission spectra and competitive binding assays by using N-phenyl-1-naphthylamine as first binding ligand and odorants as potential competitors revealed that the CsupGOBP2 protein has significant affinity to cis-11-hexadecenal (Z11-16:Ald), the main component of Ch. suppressalis pheromone and to laurinaldehyd and benzaldehyde, two general plant volatile aldehydes.

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 it
