The Change of POD and PPO Activity and Isozyme in Wheat Varieties with Different Resistance to Wheat Powdery Mildew before or after Inoculation
Bibliographic record
Abstract
Used Colorimetry and polypropylene amic gel electrophoresis(PAGE) to comparatively study the activity and isozyme of peroxidase(POD) and polyphenoloxidase(PPO) in three wheat varieties with different resistance after inoculation,Activity of peroxidase(POD) and polyphenoloxidase(PPO) showed:immune had highest POD activity before inoculation in the three varieties,and POD activity of the three varieties all appeared increasing first and then decreasing.There were no significant differences in PPO activity before inoculation,But the time of the activity peak to show up diffdrent obviously.immune,moderate and susceptible varieties showed the highest PPO activity respectively 1 day,2 days and 3 days after inoculation.Isoenzyme electrophoresis of these samples showed that difference occurred in activity of immune,moderate and susceptible POD isozyme bands occurred increased or decreased.But,PPO isozyme bands occurred diffdrent obviously in activity and numbers.The result suggested that POD and PPO may be close related with plant against Blumeria graminis f.sp.tritici.

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.
