Abstract
Localization of protochlorophyll(ide) (Pchlide) forms and chlorophyllide (Chlide) transformation process were studied by using comparative analyses of de-convoluted 77 K fluorescence spectra of barley etioplast stroma and different membrane fractions obtained by sucrose gradient centrifugation. Non-photoactive 633 nm Pchlide form was mainly located in the envelope-prothylakoid membrane mixture while the photoactive 657 nm Pchlide was dominant pigment in the prolamellar body membrane and in the soluble etioplast fraction (stroma). When these fractions were exposed to a saturating flash, conversion of photoactive Pchlide into 697 nm Chlide was preferential in the prolamellar body and in the stroma, while the 676 nm Chlide was dominant pigment form in the envelope-prothylakoid fraction. These spectral characteristics are considered to reflect molecular composition and organization of the pigment-protein complexes specific for each etioplast compartment.

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
