Abstract
The acetylation and methylation status on N-terminal regions of histones are dynamically changed and corresponded to gene regulation in eukaryotes. The quantitative and qualitative alterations of these histone modifications contribute to the regulation of structural changes in chromatin, and are associated with the status of gene activity. In plants, histone modification plays an important role in the regulation of gene expression in the process of development and vernalization. It is well known that gene expression is dynamically regulated genome-wide in response to environmental stresses. However, the detailed mechanisms of chromatin regulation in environmental stress responses have not well understood yet. We have studied the alterations of histone modifications under dehydration and rehydration conditions, and the function of histone modifying enzymes under abiotic stresses in Arabidopsis. Here, we will discuss the chromatin regulation mechanism involving histone modifications in environmental stress responses.
