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

The following day, the plates were sprayed with 0.5 M catechol (Sigma) in 50 mM potassium phosphate (pH 7.5) to distinguish the xylE -expressing colonies (yellow) from the recombinant colonies (white).
In experiments in which THP-1 cells were infected at a MOI of 50:1 (results in ~1 phagocytosed M. smegmatis bacterium per macrophage) with a mixture containing equal numbers of bacteria of the xylE -expressing control strain and a strain carrying the cosmid vector pYUB178, the ratio of recovered white colonies to yellow colonies was 1:1 at all time points (data not shown).
In this coinfection, the ratio of white (sur2) to yellow (xylE and Rv0365c expressing) colonies remained 1:1 through 12 hours and then increased to ~3:1 at 24 hrs, consistent with the above-described observations.
Replating of the yellow colonies produced a mixture of white and yellow colonies, suggesting that the expression of the xylE or aph gene in the SigE-expressing strain may be detrimental to the cell and may lead to plasmid instability.
One reporter gene, the aph gene which confers resistance to kanamycin, allows for selection of active promoters and a second reporter gene, the xylE gene which encodes catechol 2,3 dioxygenase, allows for screening for loss of promoter activity.
