Histopathology of the endophytic system and aerial shoots of <i>Arceuthobium americanum</i> infected by <i>Colletotrichum gloeosporioides</i>
Bibliographic record
Abstract
Infection of the endophytic system of Arceuthobium americanum parasitizing Pinus contorta var. latifolia by the fungus Colletotrichum gloeosporioides was assessed on naturally infected and inoculated localized dwarf mistletoe plants. Two different techniques were utilized to attempt to inoculate C. gloeosporioides into the endophytic system: the fungus was applied as Stabileze formulated product onto cut A. americanum shoots and as a mycelial plug to wounded A. americanum infected host branches. The fungus was cultured from infected shoots and the basal cup region of naturally infected A. americanum, but not pine tissues that included the endophytic system. Following inoculation of cut shoots, the shoots were abscised from the dwarf mistletoe plant, and the fungus was not isolated 1 year after inoculation. The fungus was recovered from the wounded region of infections that were inoculated with a mycelial plug, but not outside of the wounded area. Hyphae with morphology that matched that of C. gloeosporioides were observed microscopically in the shoots and basal cup region of naturally infected A. americanum, but not in the samples from the inoculated treatments. Thus, we were unable to confirm that C. gloeosporioides infected the endophytic system of A. americanum parasitizing P. contorta var. latifolia, although xylem continuity between the aerial and endophytic systems was observed.

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.
