Resource Announcement of 18 <i>Clavibacter nebraskensis</i> Genomes Isolated from Maize in Mexico
Bibliographic record
Abstract
Gram-positive Clavibacter nebraskensis is the causal agent of Goss's wilt and leaf blight of maize. The disease is documented across corn-producing regions of the United States and two Canadian provinces. In 2024, C. nebraskensis was confirmed in Mexico for the first time, posing a challenge to maize biosecurity given its status as a quarantine organism under NOM-018-FITO-1995. This finding demonstrates the necessity of establishing C. nebraskensis surveillance programs for maize in Mexico. To support this effort, 18 C. nebraskensis isolates from two states in Mexico were sequenced. Comparative genomic analysis showed that all isolates clustered with the C. nebraskensis type strain NCPPB 2581ᵀ. These genomic resources are essential for advancing research on C. nebraskensis epidemiology, biology, and evolution across North America. [Formula: see text] Copyright © 2025 The Author(s).

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.
