Epigenetic Modifications Regulate Genome Activity
Epigenetic modifications and small RNAs play an important role in gene regulation. Here, we discuss results of our Solexa/ Illumina 1G sequencing-based survey of DNA methylation, activating and repressive histone modifications, small RNAs and mRNA in the maize genome. We analyze tissue-specific epigenetic patterns, discuss antagonistic relationships between repressive epigenetic marks and highl...
متن کاملChromatin-Based Epigenetic Regulation of Plant Abiotic Stress Response
Plants are continuously exposed to various abiotic and biotic factors limiting their growth and reproduction. In response, they need various sophisticated ways to adapt to adverse environmental conditions without compromising their proper development, reproductive success and eventually survival. This requires an intricate network to regulate gene expression at transcriptional and post-transcri...
متن کاملEpigenetic regulatory elements associate with specific histone modifications to prevent silencing of telomeric genes
In eukaryotic cells, transgene expression levels may be limited by an unfavourable chromatin structure at the integration site. Epigenetic regulators are DNA sequences which may protect transgenes from such position effect. We evaluated different epigenetic regulators for their ability to protect transgene expression at telomeres, which are commonly associated to low or inconsistent expression ...
متن کاملEpigenetic Modifications: Genetic Basis of Environmental Stress Response
Genomic DNA is faithfully replicated and divided between two daughter cells in the course of each cell cycle. In order to maintain the inheritance of gene expression patterns, the cell must not only replicate the DNA, but also duplicate its chromatin structure (McNairn & Gilbert, 2003). Following replication, DNA is methylated and packaged into nucleosomes by the binding of histone octamers to ...
متن کاملPlant Responses to Abiotic Stress Regulated by Histone Deacetylases
In eukaryotic cells, histone acetylation and deacetylation play an important role in the regulation of gene expression. Histone acetylation levels are modulated by histone acetyltransferases and histone deacetylases (HDACs). Recent studies indicate that HDACs play essential roles in the regulation of gene expression in plant response to environmental stress. In this review, we discussed the rec...
