Abstract
PREMISE OF THE STUDY: Protocorm-like bodies (PLBs) of orchids are important in orchid micropropagation and outwardly resemble somatic embryos in form and development. To determine whether PLBs are truly embryogenetic, we compared PLBs with somatic embryos and zygotic embryos to determine whether they had similar surface molecules and whether hydroxyproline-rich glycoprotein (HRGP) inhibitors similarly alter their growth. METHODS: Embryogenic calluses (ECs), zygotic embryos, and protocorms were collected for histological and histochemical studies with light microscopy. The presence of JIM11 and JIM20 epitopes was determined using immunodot blots and immunolocalization procedures. The importance of wall proteins in the formation of PLBs was investigated using 3,4-dehydro-l-proline (3,4-DHP), an inhibitor of HRGP biosynthesis. KEY RESULTS: At the early stages of PLB formation, the cytoplasm of the globular cell clusters and meristemoids took on a vacuolated appearance. Starch granules and protein bodies appeared, albeit transitory in nature. Positive localizations of JIM11 and JIM20 were noted in the embryogenic culture and developing PLBs similar to zygotic embryos. The inclusion of an inhibitor to HRGPs inhibited PLB formation. CONCLUSIONS: This study demonstrates that during the early stages of PLB formation, the cells show cytological characteristics and cell wall markers similar to zygotic embryo development, justifying the statement that PLBs are indeed somatic embryos of orchids. Thus, these results suggest that PLBs could be used as an experimental embryological system for physiological or molecular characterization.

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
