阳光通过光合作用为植物生长提供必要的能量，但强光，特别是其不可分割的紫外线（UV）部分会导致胁迫，可能导致DNA，蛋白质和其他细胞成分的严重损伤。植物表现出对环境胁迫的适应，有时被称为“植物记忆”。越来越多的证据表明，植物通过细胞水平的表观遗传机制记忆生物或非生物胁迫。紫外线靶基因，如查尔酮合成酶（CHS）立即响应紫外线处理和最近确定的UV-B受体紫外线抗性基因座8（UVR 8）的研究证实了紫外线信号的快速性质。考虑到这些发现，紫外线记忆似乎是多余的。然而，一些证据表明，植物可能会发展紫外线和光胁迫的表观遗传记忆，但与其他非生物胁迫相比，研究相对较少。本文综述了植物对紫外光的驯化和适应，并讨论了基于染色质的表观遗传记忆的可能性。
Sunlight provides the necessary energy for plant growth via photosynthesis but high light and particular its integral ultraviolet (UV) part causes stress potentially leading to serious damage to DNA, proteins, and other cellular components. Plants show adaptation to environmental stresses, sometimes referred to as “plant memory.” There is growing evidence that plants memorize exposure to biotic or abiotic stresses through epigenetic mechanisms at the cellular level. UV target genes such as CHALCONE SYNTHASE (CHS) respond immediately to UV treatment and studies of the recently identified UV-B receptor UV RESISTANCE LOCUS 8 (UVR8) confirm the expedite nature of UV signaling. Considering these findings, an UV memory seems redundant. However, several lines of evidence suggest that plants may develop an epigenetic memory of UV and light stress, but in comparison to other abiotic stresses there has been relatively little investigation. Here we summarize the state of knowledge about acclimation and adaptation of plants to UV light and discuss the possibility of chromatin based epigenetic memory.
