Oxidative burst induced pseudosclerotium formation of<i>Morchella steppicola</i>Zerova on different malt agar media
Bibliographic record
Abstract
Morchella steppicola Zerova mycelia was grown on modified MS (MSK) medium and on MSK medium containing different malt content. Starvation induced an enhanced pseudosclerotium formation in a given zone of the culture. The malondialdehyde content of the mycelium at the site of pseudosclerotium formation was related to the acceleration of lipid peroxidation and oxidative stress. Superoxide dismutase activity was monitored in control and stressed vegetative hyphae subjected to malt withdrawal. In the formation zone of resting bodies, an enhanced oxidative burst was observed. The glucose and trehalose contents of M. steppicola mycelium during pseudosclerotium formation were also investigated. The glucose concentration of the mycelia approached a minimum during pseudosclerotium formation. At the same time, trehalose concentration reached a maximum in the zone of pseudosclerotium formation. The dry mass of mycelia in these zones was higher than average. The dry matter content of the pseudosclerotium-forming zones significantly exceeded the average of the whole culture. The correlation among trehalose accumulation, oxidative burst, and pseudosclerotium formation was clearly demonstrated.

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.
