Changes of antioxidative enzymes in Impatiens walleriana L. shoots in response to genetic transformation
Bibliographic record
Abstract
Impatiens walleriana L. shoots were inoculated with Agrobacterium rhizogenes A4M70GUS and the effects of genetic transformation on the catalase (CAT), superoxide dismutase (SOD) and peroxidase (POX) activities in wounded region of stems and unwounded leaves were evaluated 10, 24, 240 and 720 hours after inoculation. Following Agrobacterum infection activities of plant antioxidative enzymes changed in a time-dependent manner indicating that dynamic processes occurred during plant-Agrobacterium interaction, plant cell transformation and formation of hairy roots. Appearance of hairy roots on wound sites of shoots was observed ten days after inoculation with A. rhizogenes and the root induction frequency was 100%. Among selected hairy root lines significant differences in growth rate and biomass production were observed and an average 3-fold increase in biomass production was observed for the best growing hairy root line compared with the untransformed roots. PCR analysis showed presence of uidA, rolB, rolC and rolD genes in all analyzed I. walleriana L. hairy root lines, while amplification fragment of rolA gene was detected in 83.3% transformed lines. Efficient transformation protocol for I. walleriana L described in this work offer possibilities to generate hairy root cultures for in vitro propagation of plant viruses.

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.
