Host–parasite interactions in clubroot of crucifers
Bibliographic record
Abstract
Clubroot, caused by Plasmodiophora brassicae, is an important root disease of crucifers worldwide. In this review, the molecular aspects of clubroot pathogenesis and resistance are discussed. Topics covered include recent studies on the processes associated with infection by primary and secondary pathogen zoospores, examination of the expression patterns of P. brassicae genes at different stages of infection, and the concurrent identification of candidate genes for functional studies. Although the whole genome sequence of P. brassicae is not yet available, molecular studies of the pathogen are nonetheless moving into the genomics era. Transcriptomics and functional analyses of individual genes involved in the P. brassicae/Brassica interaction have recently been conducted to complement studies on the excellent model host, Arabidopsis thaliana. Two resistance genes have been cloned and their molecular functions illustrated, supporting suggestions that the clubroot pathosystem follows the gene-for-gene model. Although much about the pathogenesis of clubroot remains unknown, significant advances have been made in recent years, which may facilitate the identification of targets for agro-chemical development and resistance breeding.

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.
