Plants are fixed on the ground, cannot actively escape from the external hazards, and thus relies on some of their own response mechanism to defend against various external stress. Due to the limited responsiveness of the plants, the negative entropy operation of the open system is hindered, which results in the death of plants in a large number.Epigenetic regulation plays an important role in this response mechanism, mainly in DNA methylation, histone modification, chromatin remodeling, and noncoding RNA. In this paper, the regulation mechanism of epigenetic modification under various stresses and the analysis of entropy were reviewed, providing a basis for the study of crop resistance.展开更多
