Abstract
Metarhizium anisopliae is a well-characterized entomopathogenic fungus that attacks a variety of insects. Its conidia are involved in its propagation and also in its infection of host insects. To investigate the protein expression profiles and to identify the proteins related to development and pathogenesis, we performed a comparative proteomic analysis of the conidia and mycelia of an M. anisopliae strain (Ma1291). The analysis used 2-dimensional gel electrophoresis and matrix-assisted laser desorption ionization time-of-flight mass spectrometry. We detected 898 ± 37 protein spots in conidia and 1072 ± 24 in mycelia of strain Ma1291. A comparison of the 2 protein-expression profiles indicated that only 28% of protein spots were common to both developmental stages. Finally, we identified 30 proteins (19 from conidia and 11 from mycelia). The identified proteins exclusive to conidia were those involved in protective processes, appressorium formation, and degradation of the host cuticle (protease PR1H). The identified proteins exclusive to mycelia included major proteins participating in biosynthetic and energy metabolism, such as UTP-glucose-1-phosphate uridylyltransferase and heat shock protein 70. This research provides the first proteomic analysis of different developmental stages of M. anisopliae, and the results should facilitate clarification of the molecular basis of these epigenetic variations.

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
