Polyploids are widespread in plants and are important drivers for evolution and biodiversity. Allopolyploidy activates transposable elements (TEs) and causes genomic shock. Plant genomes can regulate gene expression by changing the epigenetic modification of TEs, but the mechanism for TEs to capture ...

modification are regarded as ChIP-on-chip(chromatin immunoprecipitation-on-chip) and GMAT(genomewide mapping technique).DNA methylation,as a regulatory mechanism of gene expression,also plays an important role in the process of growth and development in plants.The relationship between the degree of ...
The function of plant genomes depends on chromatin marks such as the methylation of DNA and the post-translational modification of histones. Techniques for studying model plants such as Arabidopsis thaliana have enabled researchers to begin to uncover the pathways that establish and maintain chromatin ...
RNA-directed DNA methylation (RdDM) is the major small RNA-mediated epigenetic pathway in plants. RdDM requires a specialized transcriptional machinery that comprises two plant-specific RNA polymerases — Pol IV and Pol V — and a growing number of accessory proteins, the functions of which in th...
Plant developmental abnormalities have been detected in mutants with disturbed epigenetic modifications, some of which are heritable. An allele of a heritable variant, which is caused by a change in an epigenetic modification without a change in the DNA sequence, is termed an "epiallele". In A....
(TEs). In plants, de novo DNA methylation is established by a specific RNA-directed DNA methylation (RdDM) pathway. InArabidopsis, a canonical RdDM model proposes that single-stranded RNA (ssRNA), produced by RNA POLYMERASE IV (Pol IV), can be recognized by RNA-DEPENDENT RNA POLYMERASE 2 ...
They therefore offer a possible mechanism for stress memories in plants. Recent studies have yielded evidence indicating that epigenetic mechanisms are indeed essential for stress memories and adaptation in plants. 展开 关键词: DNA methylation Epigenetics Histone modification Small RNA Stress responses ...
