Abstract：
Plants have several mechanisms to adapt or acclimate to environmental stress. Morphological, physiological, or genetic changes are examples of complex plant responses. In recent years, our understanding of the role of epigenetic regulation, which encompasses changes that do not alter the DNA sequence, as an adaptive mechanism in response to stressful conditions has advanced significantly. Some studies elucidated and synthesized epigenetic mechanisms and their relationships with environmental change, while others explored the interplay between epigenetic modifications and environmental shifts, aiming to deepen our understanding of these complex processes. In this study, we performed a systematic review of the literature to analyze the progression of epigenetics studies on plant species\' responses to abiotic factors. We also aimed to identify the most studied species, the type of abiotic factor studied, and the epigenetic technique most used in the scientific literature. For this, a search for articles in databases was carried out, and after analyzing them using pre-established inclusion criteria, a total of 401 studies were found. The most studied species were Arabidopsis thaliana and Oryza sativa, highlighting the gap in studies of non-economic and tropical plant species. Methylome DNA sequencing is the main technique used for the detection of epigenetic interactions in published studies. Furthermore, most studies sought to understand the plant responses to abiotic changes in temperature, water, and salinity. It is worth emphasizing further research is necessary to establish a correlation between epigenetic responses and abiotic factors, such as extreme temperatures and light, associated with climate change.
摘要：
植物具有几种适应或适应环境胁迫的机制。形态学,生理,或遗传变化是复杂植物反应的例子。近年来,我们对表观遗传调控作用的理解，其中包括不改变DNA序列的变化，作为应对压力条件的适应性机制已经显着进步。一些研究阐明和合成了表观遗传机制及其与环境变化的关系，而其他人则探索了表观遗传修饰和环境变化之间的相互作用，旨在加深我们对这些复杂过程的理解。在这项研究中,我们对文献进行了系统回顾,以分析植物物种对非生物因素反应的表观遗传学研究进展.我们还旨在确定研究最多的物种，研究的非生物因素的类型，以及科学文献中最常用的表观遗传技术。为此，在数据库中搜索文章，在使用预先建立的纳入标准进行分析后，共发现401项研究。研究最多的物种是拟南芥和水稻，强调非经济和热带植物物种研究的差距。在已发表的研究中，甲基化DNA测序是用于检测表观遗传相互作用的主要技术。此外，大多数研究试图了解植物对温度非生物变化的反应，水,和盐度。值得强调的是进一步的研究是必要的，以建立表观遗传反应和非生物因素之间的相关性，比如极端的温度和光照，与气候变化有关。
