Abstract
In nature, plants are regularly exposed to biotic and abiotic stress conditions. These conditions create potential risks for survival. Plants have evolved in order to compete with these stress conditions through physiological adjustments that are based on epigenetic background. Thus, the ecological signals create different levels of stress memory. Recent studies have shown that this stress-induced environmental memory is mediated by epigenetic mechanisms that have fundamental roles in the aspect of controlling gene expression via DNA methylation, histone modifications and, small RNAs and these modifications could be transmitted to the next generations. Thus, they provide alternative mechanisms to constitute stress memories in plants. In this review, we summarized the epigenetic memory mechanisms related with biotic and abiotic stress conditions, and relationship between priming and epigenetic memory in plants by believing that it can be useful for analyzing memory mechanisms and see what is missing out in order to develop plants more resistant and productive under diverse environmental cues.
