Constitutive expression of human lactoferrin and its N-lobe in rice plants to confer disease resistance
Bibliographic record
Abstract
The milk protein, lactoferrin, is known to have antibacterial, antiviral, and antifungal activities. To explore the possibility of conferring disease resistance in plants by expressing this protein, the gene for the full-length human lactoferrin (HLF), as well as the N-lobe, the N-terminal half molecule (HLFN), was introduced into rice plants and expressed constitutively under the control of the cauliflower mosaic virus 35S promotor. Western blot analysis of leaves from HLF-transgenic rice plants showed an 80 kDa-band, which was about 1-2 kDa less than human milk lactoferrin. HLFN was expressed as a 45-kDa protein and retained its heparin-binding property. Deglycosylation experiments suggested that both proteins produced by the plants had plant-type oligosaccharide chains. The transgenic rice plants were assessed for resistance against disease-causing bacteria, virus, and fungi. Of the pathogens tested, significant resistance against Burkholderia (Pseudomonas) plantarii, the causative agent of bacterial seedling blight disease, was observed in the transgenic plants expressing HLF or HLFN.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
