MCT1 plays crucial roles in conidiation, lactate metabolism and pathogenicity in <i>Colletotrichum gloeosporioides</i>
Bibliographic record
Abstract
Monocarboxylate transporters (MCTs) play vital roles in carbon source assimilation, drug resistance and virulence. However, the underlying function of MCTs in fungal pathogenesis and development has not been investigated in detail. In this study, we identified and characterized the monocarboxylate transporter gene MCT1 of Colletotrichum gloeosporioides, which is the causal agent of Glomerella leaf spot of apple. Mct1 is localized to the mitochondria and may mediate the uptake of lactate to the cell. However, MCT1 was constitutively expressed but showed an enhanced expression level in response to the presence of the extracellular lactate. Our results indicate that Mct1 plays a role in the metabolism of lactate. More importantly, the Δmct1 mutant showed significantly poor conidiation and a defect in host infection. Taken together, our studies provide evidence for Mct1 as a mitochondrial transmembrane protein mediating conidiation, the metabolism of lactate, and the pathogenicity of C. gloeosporioides.

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.
