How can you use “t-dna” in a sentence? Here are some example sentences to help you improve your vocabulary:
Once an insertion of T-DNA is detected in a kinesin, the sequence of the amplified product could be obtained to identify the kinesin involved.
Together, these results suggest that PTGS in certain oligomeric T-DNA loci is unstable and has a tendency to progress to TGS.
C73 contains at least three copies of a T-DNA comprising the 35S:GFP-COP1 gene as well as a kanamycin resistance gene driven by the nopaline synthase promoter ( nos:nptII ). The C73 locus is silenced transcriptionally (TGS) but retains partial expression of both nptII and GFP-COP1 . GFP-COP1 remains expressed in the seedling root but is largely silenced in the shoot.
These results underscore the similarity between trans-silencing and paramutation, because in both cases epialleles are often silenced incompletely and may also adopt novel regulatory patterns [ 4 10 ] , for example light inducibility [ 33 ] . Perhaps, silencing at the dimeric E82 locus involves a hierarchical relationship between its two intact T-DNAs.
The trans-silencers as well as their targets reside in single-copy, gene-rich regions that are only sparsely populated with repetitive or transposable elements, features that have been shown to mediate epigenetic activity in other cases [ 18 31 32 ] . Therefore trans-silencing of GFP-COP1 is probably not mediated by transgene flanking sequences [ 27 ] . In contrast, as with other genes cited above, trans-silencing ability is correlated with transgene locus structure, given that the C73 and C97 trans-silencers contain multiple T-DNAs while their targets, E82 and L91, are essentially dimeric and monomeric, respectively.
