WebJan 19, 2010 · Natural Epigenetic Variations Correlate with Changes in Transcript Abundance among Hybrids and Parental Lines. Comparative genomics has revealed a rapid and dramatic divergence of genomic sequences between indica and japonica rice subspecies (Ma and Bennetzen, 2004). WebApr 27, 2024 · It has been said that “epigenetics emphasizes heritable changes in gene expression that cannot be tied to genetic variation” (Richards 2006). A critical consequence of epigenetic effects is that the same genotype can display diverse phenotypes due to differential modification of the epigenetic state. ...

WebTaken together, our data suggest that locus-specific epigenetic divergence between the parental lines can directly or indirectly trigger heterosis in Arabidopsis hybrids independent of genetic changes. These results add to a growing body of evidence that points to epigenetic factors as one of the key determinants of hybrid performance.
