Example sentences for: paramutation

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

  • 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 methylation status of the maize r1 genes and Arabidopsis PAI genes is altered upon paramutation [ 12 19 ] , while that of maize b1 is not [ 1 ] , except, in the non-conventional way, in the distal paramutation-control region of b1 [ 18 ] . Conversely, extensive exposure of a wild-type Arabidopsis SUPERMAN allele to a heavily methylated and transcriptionally silenced epiallele did not reveal any trans-silencing [ 20 ] .

  • Whether the imprint imposed by a paramutagenic locus is relayed effectively from the first target locus to a secondary target locus is a variable characteristic of paramutation systems, and this has implications for the speed of epiallele conversion within outcrossing populations.

  • If allelic, such non-Mendelian interactions are referred to as paramutation.

  • Epigenetic activity, defined here as partnership in heritable trans-silencing or paramutation, is not predictable from the DNA sequence alone, and its molecular basis is incompletely understood.
