Petunia CHS also lends itself to detect somatic transitions in epialleles due to its indeterminate growth habit, whereas Arabidopsis COP1 is more suitable for monitoring early epigenetic activity in seedlings and rosette plants.
CHS Cardiovascular Health Study
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 ] .
The experimental strategy of monitoring heritable epialleles via their effect on visible cosuppression patterns has been pioneered in the chalcone synthase (CHS) family of petunia and Arabidopsis [ 4 10 30 ] . For comparison, CHS trans-silencing offers exquisite sensitivity, in part due to the cell autonomy of its pigmentation phenotype, whereas COP1 essentially yields a whole-plant phenotype.
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.
