e0“only a few stems of the parasite appeared above the soil”
e1“The most significant improved tolerance was to P. aegyptiaca . Unlike WT/EV plants that were heavily infected by the parasite, the transgenic AroG plants strongly inhibited P. aegyptiaca development, and only a few stems of the parasite appeared above the soil”
e2“tobacco ( Nicotiana tabacum ) plants were transformed with a bacterial gene (AroG)”

Other claims from this paper (11)
- Observation Low AroG expression produced minor metabolic changes and a normal phenotype.
- Observation High AroG accumulation caused a dramatic metabolic shift with normal or deleterious morphology.
- Intervention effect Transgenic tobacco leaf phenylalanine increased up to 43-fold versus controls.
- Intervention effect Transgenic tobacco leaf tyrosine increased up to 24-fold versus controls.
- Intervention effect Transgenic tobacco leaf tryptophan increased up to 10-fold versus controls.
- Association Phenylpropanoid metabolites were higher alongside increased phenylalanine.
- Intervention effect AroG tobacco showed improved salt tolerance.
- Intervention effect AroG tobacco did not show improved oxidative stress tolerance.
- Intervention effect AroG tobacco did not show improved drought stress tolerance.
- Intervention effect AroG tobacco strongly inhibited parasite development versus heavily infected controls.
- Mechanism The authors suggest phenylpropanoid accumulation may delay parasite development.
