Alleles of Maize Result in Tissue-Specific Mosaicism

alleles have unique gene structure and copy number which have been proposed to influence the epigenetic regulation of tissue-specific gene expression. For example, the presence of tandem-repeats has been correlated with the suppression of pericarp pigmentation though a mechanism associated with increased DNA methylation. has reduced DNA methylation at a distal enhancer and elevated DNA methylation downstream of the transcription start site. may have disrupted the epigenetic mechanisms that stably confer tissue-specific expression
