Functions of the AP2/ERF family transcription factor AIL7 in immunity against soilborne clubroot pathogen in Arabidopsis
Bibliographic record
Abstract
Abstract Soilborne pathogens can be highly devastating, and clubroot, caused by Plasmodiophora brassicae , is particularly destructive to cruciferous plants. Although many AP2/ERF family transcription factors (TFs) have crucial physiological functions, very little is known regarding their functions in the context of soilborne diseases. Here we investigated the roles of AINTEGUMENTA-LIKE 7 (AIL7), an AIL sub-family TF in the AP2/ERF family, in plant immunity against clubroot. Unexpectedly, both AIL7 overexpression and mutant Arabidopsis lines exhibited increased tolerance to P. brassicae . Subsequent analysis revealed significant transcriptional alterations in genes linked to pathogen response, along with notable differences in genes associated with salicylic acid (SA) and jasmonic acid (JA) defense pathways, compared to wild-type plants. Interestingly, there was a tendency for up-regulation of SA- and JA-related genes in AIL7 overexpression and mutant lines in the absence, rather than presence, of P. brassicae . Subsequent phytohormone analyses confirmed these results. Taken together, AIL7 has an important role in maintaining constitutive systemic acquired resistance, involving phytohormone mediated defense, and this, rather than an accumulation of SA following P. brassicae challenge, primes the plants for improved clubroot resistance, which would shed light on exploring the functions of other AP2/ERF family TFs in plant immunity against soilborne pathogens.

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.
