Boeremia tuber rot of sweet potato caused by <i>B. exigua</i>, a new post-harvest storage disease in China
Bibliographic record
Abstract
A new post-harvest storage disease was observed on sweet potato (Ipomoea batatas L.) in Zhejiang Province, China in November 2014. A species of Boeremia was constantly isolated from diseased tissues with typical symptoms of storage tuber rot. The isolates were identified as Boeremia exigua based on morphological characteristics and phylogenetic analyses of the internal transcribed spacer (ITS) region and 5.8S ribosomal DNA, the 28S large subunit ribosomal RNA (LSU) gene, the β-tubulin (TUB) gene and the actin (ACT) gene. The pathogenicity of the fungal isolates was confirmed through inoculation experiments. This is the first report of Boeremia tuber rot caused by B. exigua on sweet potato in China.

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.
