Infection by <i>Colletotrichum truncatum</i> in resistant and susceptible lentil genotypes
Bibliographic record
Abstract
The process of infection of lentil (Lens culinaris Medik.) by Colletotrichum truncatum (Schwein.) Andrus and W.D. Moore was studied on lentil on a partially resistant line and a susceptible cultivar, using one highly virulent and one moderately virulent isolate. Leaves and stem tissue were sampled at regular intervals from 1 to 144 h postinoculation (hpi). Infection was characterized by a symptomless phase lasting 3 days and a destructive phase between 3 and 6 days after inoculation. Conidia germinated within 3–6 hpi and formed appressoria at 6–12 hpi. Infection pegs from the appressoria penetrated the cuticle and epidermal cells directly. Hyphae in host tissues grew inter- and intra-cellularly, starting at 24 hpi. Differences in pathogen development on the two lentil genotypes became apparent at 48 hpi. In the resistant line, deposits of material stained with aniline blue were prominent during infection by the moderately virulent isolate, but were not produced during infection by the highly virulent isolate. No deposits were observed in the susceptible cultivar. Also, hyphal spread was slower and phenolic compounds accumulated more quickly in the resistant line, resulting in fewer, smaller lesions than in the susceptible cultivar.

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.
