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.

植物的表观遗传记忆和启动

在自然界中，植物经常暴露在生物和非生物胁迫条件下。这些条件为生存带来了潜在风险。植物已经进化以通过基于表观遗传背景的生理调整与这些压力条件竞争。因此，生态信号会产生不同程度的压力记忆。最近的研究表明，这种压力诱导的环境记忆是由表观遗传机制介导的，这些机制在通过 DNA 甲基化、组蛋白修饰和小 RNA 控制基因表达方面具有基本作用，并且这些修饰可以传递给下一代。因此，它们提供了在植物中构成应激记忆的替代机制。在这篇综述中，我们总结了与生物和非生物胁迫条件相关的表观遗传记忆机制，
