Epistatic influence in tomato Ve1‐mediated resistance
Bibliographic record
Abstract
Resistance to Verticillium wilt disease is associated with the tomato Ve-locus; however, the individual functional roles of Ve1 and Ve2 in host plants remain controversial. As a first step towards Ve mutational analyses in planta, the Ve1 coding region from a resistant tomato near-isoline (cv. Craigella GCR218) was introduced into a susceptible near-isoline (cv. Craigella GCR26). 35S:Ve1 plants segregated into two distinct classes; roughly half were resistant and half were susceptible. Ve1 transcript levels were up-regulated in both classes compared to wild-type plants, showing stable transgenic expression. Expression analysis of Ve2 revealed that mRNA levels were similar between 35S:Ve1 and wild-type tomatoes, demonstrating that Ve1 transgene introduction does not alter endogenous Ve2 expression. Overall, the results of this study confirm the functional role of Ve1 protein in resistance to the vascular fungal pathogen V. dahliae race 1 (Vd1), but suggest that a yet undefined factor exerts an epistatic influence on the Ve1 gene.

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.
