Disruption of a gene encoding glycerol 3-phosphatase from<i>Candida albicans</i>impairs intracellular glycerol accumulation-mediated salt-tolerance
Bibliographic record
Abstract
Intracellular glycerol accumulation is critical for Candida albicans to maintain osmolarity, and therefore defects in glycerol homeostasis can have severe effects on the morphogenetic plasticity and pathogenicity of this fungus. The final step of glycerol synthesis involves the dephosphorylation of glycerol 3-phosphate by glycerol 3-phosphatase (GPP1). We have identified a single copy of the GPP orthologous gene (GPP1) in the C. albicans haploid genome, as well as the paralogous gene 2-deoxyglucose-6-phosphate phosphatase (DOG1); both belong to a family of low molecular weight phosphatases. A knockout of the GPP1 gene in C. albicans caused increased susceptibility to high salt concentrations, indicating a deficiency in osmoregulation. Reintroduction of the GPP1 gene complemented the impairment of salt-tolerance in the gpp1/gpp1 mutant. Northern blot analysis showed that the GPP1 gene was strongly responsive to osmotic stress, and its transcriptional expression was positively correlated with intracellular glycerol accumulation. These results demonstrate that the GPP1 gene plays an important role in the osmoregulation in C. albicans.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
