Abstract

fetched live from OpenAlex

Four glutathione S-transferase (GST) genes, NbGSTU1, NbGSTU2, NbGSTU3, and NbGSTF1, were amplified from cDNA of Nicotiana benthamiana leaves infected with Colletotrichum destructivum using primers based on conserved regions of N. tabacum GST sequences. Expression of NbGSTU1 and NbGSTU3 increased progressively during infection by either C. destructivum or Colletotrichum orbiculare, except for a slight decrease by NbGSTU1 late in the infection, whereas NbGSTU2 and NbGSTF1 expression remained relatively constant. Each of the four genes was cloned into a PVX vector for virus-induced gene silencing, and reduced expression of the four genes was detected by RT-PCR. A statistically significant increase in susceptibility of N. benthamiana to infection following gene silencing was found only for NbGSTU1-silenced plants, which had 130% more lesions and 67% more colonization by C. orbiculare compared with control plants. These results demonstrate that the different GST genes respond in different ways to fungal infection, and at least one plant GST gene has an important role in disease development.

Teacher imitation

Not 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.
