Pathogenesis-related gene (<i>PvPR1</i> and <i>PvPR2</i>) expression involved in <i>Meloidogyne incognita</i> parasitism and resistance reactions of common bean genotypes in host–nematode interactions
Bibliographic record
Abstract
Pathogenesis-related (PR) genes are useful molecular markers, and gene expressions are activated in the reaction of plant-parasitic nematodes. Determining the PR gene expression and the resistance reaction of Phaseolus vulgaris L. genotypes against root-knot nematode are valuable for understanding plant–nematode interactions. However, resistance reactions of P. vulgaris genotypes and the gene expression of host–nematode interactions are not fully understood. Therefore, this study aimed to determine the expression of PR genes during the infection of Meloidogyne incognita on resistant and susceptible bean varieties at 1, 3, 5, and 7 days postinfection (dpi). The results revealed that one genotype gave a reaction as “immune”, and numerous genotypes were susceptible. The expression of PvPR1 and PvPR2 genes reached the highest peak at 1 dpi in nematode-infected immune plants, and the expression of PvPR1 reached 5 dpi in susceptible plants. In conclusion, PR genes involved in nematode resistance and parasitism and the immune common bean genotype have great potential in breeding programs and understanding the exact location of resistance on the gene map would be advantageous as future work.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
