Analysis of thaumatin-like protein (TLP) gene family in tea plant revealed that CsTLP8 contributes to tea blister blight resistance
Bibliographic record
Abstract
BACKGROUND: Thaumatin-like proteins (TLPs) belong to the PR-5 family of the pathogenesis-related (PR) proteins, and have been widely reported in plants for their important role in resisting pathogenic bacteria. However, people know very little about the function it plays in helping tea plants resist tea blister blight. RESULTS: In the tea plant, a total of 43 CsTLPs were detected. According to the evolutionary tree analysis, these genes can be divided into 9 subfamilies. Through promoter analysis, a substantial quantity of elements associated with stress, hormone response, as well as growth and development were identified. The collinearity analysis indicates that the sequences of multiple CsTLPs genes have high homology in tea plants. The combination of transcriptome analysis and qRT-PCR demonstrated that the expression of CsTLP8, CsTLP23, CsTLP28 and CsTLP34 were significantly up-regulated after tea blister blight infection. In addition, we have verified the functionality of CsTLP8. CsTLP8 is localized in cytoplasm, and has β-1,3-glucanase activity. Transient overexpression of CsTLP8 in tobacco can significantly increase POD and CAT activities and decrease hydrogen peroxide content. CONCLUSIONS: The results will help to better understand the role of CsTLPs gene family in tea blister blight, and provide theoretical support for improving disease resistance of tea trees and breeding new varieties resistant to disease.

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.
