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

Together, these results suggest that PTGS in certain oligomeric T-DNA loci is unstable and has a tendency to progress to TGS.
PTGS and trans-silencing are similarly intertwined in other cases, for example in the epimutable petunia CHS41 locus [ 10 ] . PTGS often leads to DNA methylation, although primarily in coding regions [ 35 ] . However, DNA methylation of promoters, more easily aligned with transcriptional silencing, can be RNA mediated if suitable double stranded RNA versions of the promoter sequence are transcribed, either fortuitously or by design [ 36 37 38 39 40 ] . Therefore, there may be a natural tendency for PTGS loci to mature to TGS and associated trans-silencing, which in turn could prove problematic in applying PTGS in commercial plant breeding programs.
TGS, within two transgenic generations.
To recap: by 1998—the year in which RNAi was reported—plant scientists had documented sequence-specific RNA degradation (PTGS), sequence-specific DNA methylation that triggered TGS, and RNA-directed DNA methylation.
TGS was revealed when two different transgene complexes were introduced in sequential steps into the tobacco genome.
