Transcriptional landscape of Brachypodium distachyon roots during interaction with Bacillus velezensis strain B26
Bibliographic record
Abstract
Plant growth promoting rhizobacteria (PGPR) communicate with plants through roots. The molecular mechanism by which plants and PGPR respond to each other is not very well known. In the current study, we did RNA sequence analysis of Brachypodium distachyon Bd21-3 roots inoculated with PGPR, Bacillus velezensis strain B26. From our list of differentially expressed genes, we concentrated on transcripts that have a high possibility of participating in plant-PGPR interaction. Transcripts associated to the hormone signalling pathway were differentially expressed. We identified the upregulation of various transcripts linked to ion transporters. Reduction in expression of defense signalling genes indicated that B26 suppresses the plant defense mechanisms to begin successful interaction with roots. Transcripts associated with lignin branch of the phenylpropanoid pathway were upregulated as well, leading to more accumulation of lignin in the cell wall which enhances mechanical strength of plants. Overall, this study is an excellent resource for investigating associations between plant-PGPR interactions.

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.
