FocECM33, a GPI-anchored protein, regulates vegetative growth and virulence in Fusarium oxysporum f. sp. cubense tropical race 4
Bibliographic record
Abstract
ECM33, a glycosylphosphatidylinositol (GPI)-anchored protein, is important for fungal development and infection through regulating fungal cell wall integrity, however, the functions of its orthologs in pathogenesis have not been characterized in Fusarium oxysporum. Here, we discovered a GPI-anchored protein, FocECM33, which is required for vegetative growth and virulence of Fusasium oxysporum f. sp. cubense tropical race 4 (Foc TR4). FocECM33 was highly upregulated during the early infection process of Foc TR4 in banana roots. The targeted disruption of FocECM33 led to decreased hyphal growth, increased sensitivity to cell wall stresses and reduced virulence on banana plantlets. Furthermore, ΔFocECM33 mutant demonstrated a cell morphology defect, elevated ROS production and increased chitin content. Transcriptome analysis showed that FocECM33 has a significant influence on the production of various secondary metabolites and regulation of many biosynthetic processes in Foc TR4. Taken together, it seems FocECM33 contributes to the virulence of Foc TR4 through regulating the process of hyphal growth, ROS production and chitin synthesis.

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.
