Words similar to rhizogenes
Example sentences for: rhizogenes
How can you use “rhizogenes” in a sentence? Here are some example sentences to help you improve your vocabulary:
Strain K84 biological control is primarily due to production of two plasmid-encoded antibiotics, agrocins 84 and 484, encoded by genes on pAgK84 and pAgK434 respectively [ 5 ] . Agrocin 84, an adenosine analog [ 6 ] , is effective against tumorigenic strains carrying nopaline/agrocinopine tumor-inducing plasmids, and requires the acc system in the target strain for activity [ 7 ] . Agrocin 434, a di-substituted cytidine analog, is effective against, and specific for, a broad range of A. rhizogenes strains [ 8 ] . Curing of either agrocin-encoding plasmid results in reduction of biological control activity [ 9 ] . Thus, K84 demonstrates the efficacy of antibiosis for crown gall biological control.
Agrobacterium rhizogenes strain K84 is the most studied crown gall biological control strain and is commercially utilized for crown gall disease control worldwide.
Furthermore, TFX is inhibitory towards all tested species of Agrobacterium [ 12 ] . 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 is capable of producing TFX by addition of the stable plasmid, pT2TFXK, which contains the tfx operon but not tfuA [ 11 12 20 ] . 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.
