These results suggest that TFX production would enhance crown gall biological control for other biological control strains, such as A. rhizogenes K84, and on other host plants, especially where a mixed inoculum of different tumorigenic Agrobacterium species occurs.
Agrobacterium rhizogenes strain K84 is the most studied crown gall biological control strain and is commercially utilized for crown gall disease control worldwide.
Thus, K84 demonstrates the efficacy of antibiosis for crown gall biological control.
TFX production effectively enhances crown gall biological control by Agrobacterium vitis F2/5.
This suggests that TFX production by crown gall biological control strains of Agrobacterium, such as A. rhizogenes K84 and A. vitis F2/5, may be enhanced by TFX production.
Strains that are susceptible to the antibiotic in vitro, such as A. vitis strain CG78, are able to infect the plant in the presence of F2/5 [ 3], and Tn5 mutants of F2/5 lacking F2/5 antibiotic production appear to be unaffected in crown gall biological control [ 4].
The profile area of RKN galls in roots transformed with AtPAD4 was 86% smaller than that of RKN galls on control roots (Table 5).
Although A. vitis F2/5 is an effective crown-gall biological control agent against most tumorigenic A. vitis strains when co-inoculated with a tumorigenic strain, it is not an effective against all strains of A. vitis.
To firmly establish that Cox I/II inhibition by aspirin increases bile acid excretion, [C]-glycocholic acid was injected into the tail vein of mice, and after 30 min the tracer was quantified in gall bladders of control and aspirin-treated animals (Wang et al., 2001).
Carlotta Gall (NYT) HUNGARY: MEDIA CONTROL GROWS -- The government tightened its grip on the state news media by electing another oversight body containing no opposition members, in violation of the media law, the opposition said.
