How can you use “singlet” in a sentence? Here are some example sentences to help you improve your vocabulary:
Here, combining a master locus (C73) with a non-allelic singlet locus possessing 100% sequence identity (L91) resulted in immediate trans-silencing, as seen by a reduction of GFP-COP1 expression and block of cosuppression, which was stably maintained in the presence or absence of the master locus.
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repeat structures and singlet loci, which reside in essentially single-copy environments of Arabidopsis ( [ 27 ] and unpublished observations).
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.
In our system, a trans-silenced singlet gene (L91') was able to trans-silence a naive homolog (E82) within a single generation.
In contrast, in the PAI gene family, combining the master locus (WS ecotype PAI1/PAI4 ) with a non-allelic singlet target locus possessing 100% sequence identity (Columbia PAI2 ) resulted in methylation after two generations of heterozygous contact, and methylation became more pronounced after another two generations [ 12 ] . Likewise, in the petunia CHS gene family, interaction between an epiallele of the direct-repeat locus, CHS41, with two types of target loci, either an unlinked inverted repeat locus or a more naïve allele of CHS41, was initially additive and only became suppressive in the second generation [ 4 10 ] .
