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

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.
Antibiotic production and resistance functions are encoded by the seven-gene tfx operon and the unlinked tfuA gene [ 10 11 ] . TFX is derived from post-translational cleavage and modification of the tfxA gene product.
As all strains of A. vitis tested were sensitive to TFX both in this work and in a previous study [ 12 ] , experiments were conducted to determine the effectiveness of a TFX-producing, avirulent strain of A. vitis in the prevention of crown gall caused a three strains of A. vitis.
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.
TFX is rapidly degraded in nonsterile soil but is readily extractable from sterile soil inoculated with a TFX-producing strain, suggesting that TFX is sensitive to in situ proteolysis [ 14 ] . Despite this rapid turnover, TFX production confers enhanced nodulation efficiency upon TFX-producing Rhizobium strains under field conditions [ 15 ] .
