Biocontrol of Xanthomonas axonopodis pv. passiflorae With Bacteria Isolated From Passion Fruit
Bibliographic record
Abstract
The yellow passion fruit Passiflora edulis Sims f. flavicarpa Deg is affected by the bacterium Xanthomonas axonopodis pv. passiflorae (Pereira) Dye, causing the bacterial blight disease, for which no effective bactericide is available. The use of live microorganisms in the treatment of pests have shown positive results in the control. This research sought to select bacteria residing in the passion fruit phyllosphere to function as a biocontrol agent of X. axonopodis pv. passiflorae. The selected bacteria were isolated from the passion fruit tree leaves collected in four municipalities of the state of Roraima, and thermostable compounds test and greenhouse test were performed. In total, 28 bacterial isolates were obtained. In the test with thermostable compounds, the isolates RR02, RR04, RR06, RR14, RR16, RR17, RR19, RR20, RR21, RR22, RR23, RR25, and RR27 stood out. In the greenhouse tests, the isolates RR03, RR07, RR09, RR13, RR16, RR21, and RR23 stood out. The results showed potential for the control of X. a. pv. passiflorae in in vitro and in vivo tests.
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.
