Example sentences for: tfx

How can you use “tfx” in a sentence? Here are some example sentences to help you improve your vocabulary:

However, the level of susceptibility was lower than predicted based upon previous TFX sensitivity measurements with CG48 and CG74 [ 12 ] . No zones of A. vitis growth inhibition were observed around R. leguminosarum T24 colonies, and only relatively small zones were observed around R. etli CE3(pT2TFXK), which produces more TFX than T24.
These effects are due to TFX production as demonstrated by the lack of efficacy of F2/5 against CG49, CG435, and CG78, and by the lack of efficacy of the near-isogenic TFX-non-producing F2/5(pT2TX3K) against CG78.
As a result, F2/5 is an ideal strain in which to test the ability of the TFX system to confer biological control of crown gall disease and to broaden the host-range efficacy of a known biological control strain.
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.
Plasmids pT2TFXK and pT2TX3K confer resistance to TFX, tetracycline, and kanamycin with pT2TFXK also providing TFX production to a host strain [ 20 ] . Since strains F2/5 and F2/5(pT2TX3K) produced no zones of inhibition against ANU794 or ANU794(pT2TX3K) (data not shown), F2/5(pT2TFXK) is producing TFX.
