Words similar to paramutation
Example sentences for: paramutation
How can you use “paramutation” in a sentence? Here are some example sentences to help you improve your vocabulary:
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.
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.
Likewise, Arabidopsis PAI2 and PAI3 genes that have been trans-methylated by the PAI1/PAI4 locus do not transfer their methylation status to naive singlet genes [ 12 ] . In fact, there are few well-documented cases for the non-allelic relay of trans-silencing ability [ 11 24 ] . Does this amount to an operational difference between allelic (paramutation) and non-allelic (trans-silencing) interactions, or does it simply reflect a lack of data?
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.
These data suggest that the competence for trans-silencing may be transferred between non-allelic transgenes, reminiscent of the allelic transfer of epigenetic activity during paramutation.
