Association of <i>Gluconacetobacter diazotrophicus</i> with roots of common bean (<i>Phaseolus vulgaris</i>) seedlings is promoted in vitro by UV light
Bibliographic record
Abstract
Gluconacetobacter diazotrophicus is a diazotrophic endophyte that is a potential biofertilizer. Little is known about the mechanisms of G. diazotrophicus interaction with its host plants. We tested the effect of UV light, as an inducer of secondary metabolite accumulation, on the association between common bean ( Phaseolus vulgaris L.) seedling roots and G. diazotrophicus. UV light irradiation of seedlings 4 h prior to bacterial inoculation increased the number of bacterial cells associated with the roots by 5.65-fold with respect to a nonirradiated control (p < 0.05). Gluconacetobacter diazotrophicus associates with root hairs and root border cells. Aggregation of bacterial cells was observed in root structures from UV-induced seedlings. Secondary metabolite accumulation was also observed in roots from UV-irradiated seedlings.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
