Abstract
Herein the wound‐induced expression of a set of PR10 genes ( PmPR10 ) from Pinus monticola (Dougl. Ex D. Don) is described. Thirteen different PmPR10 cDNAs were isolated and their nucleotide sequences were determined from wounded needles. Northern blot analysis showed that PmPR10 gene expression was activated with both local and systemic responses after wounding, and the accumulation of PmPR10 transcript was much more abundant and rapid in wounded needles than in unwounded tissues. Western immunoblot analysis demonstrated that PmPR10 protein synthesis was activated upon wounding, suggesting that the expression of the wound‐activated PmPR10 gene was regulated at the transcription level. In wounded needles, the PR10 protein level increased from day 1 to day 8 after treatment. Western immunoblot analysis following isoelectric focusing and two‐dimensional electrophoresis revealed that nine PmPR10 proteins accumulated to different extents after wounding. These proteins have a molecular mass of about 18 kDa with different isoelectrical points ranging from 5.2 to 6.0. Wound‐inducible PmPR10 proteins were differentially expressed in response to cold‐hardening and fungal infection. The wound‐induced PmPR10 protein accumulation was enhanced by the wound‐signal compound methyl jasmonate and okadaic acid, a specific inhibitor of type 1 or type 2 A serine/threonine protein phosphatases. However, it was partially suppressed by salicylic acid and abscisic acid. These data provide an opportunity to elucidate further the signal transduction pathway involved in the activation of PmPR10 protein synthesis in the defence response of white pine against mechanical injury.

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
