Example sentences for: pai
How can you use “pai” in a sentence? Here are some example sentences to help you improve your vocabulary:
It is informative to compare the epigenetic interactions of the 35S:GFP-COP1 transgenes with those of the PAI (trans)genes, the only other well-characterized system in Arabidopsis [ 12 ] . Both gene sets consist of relatively simple repeat structures and singlet loci, which reside in essentially single-copy environments of Arabidopsis ( [ 27 ] and unpublished observations).
Seac Pai Van Park, on the west coast of the island is an interesting natural preserve with aNatural History Museum.
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?
In contrast, a trans-methylated singlet PAI2 gene did not trans-methylate a naive allelic PAI2 gene within three generations [ 12 ] . Additional experimentation may eventually provide an answer to the question of what controls the efficiency of such epigenetic interactions.
Paramutation has been studied extensively for four maize loci that encode transcriptional regulators of pigment biosynthesis [ 1 ] . Paramutation has also been investigated in the Arabidopsis PAI gene family, at the a1 and chalcone synthase (CHS) transgene loci in petunia, and in a number of other cases [ 2 3 4 ] . The Arabidopsis resistance gene BAL/CPR1 displays a related form of epigenetic instability [ 5 6 ] . Interactions resembling paramutation also occur among non-allelic transgene loci with DNA sequence homology.
