Current research in basic and applied knowledge of plant science has aimed to unravel the role of the interaction between environmental factors and the genome in the physiology of plants to confer the ability to overcome challenges in a climate change scenario. Evidence shows that factors causing environmental stress (stressors), whether of biological, chemical, or physical origin, induce eustressing or distressing effects in plants depending on the dose. The latter suggests the induction of the "hormesis" phenomenon. Sustainable crop production requires a better understanding of hormesis, its basic concepts, and the input variables to make its management feasible. This implies that acknowledging hormesis in plant research could allow specifying beneficial effects to effectively manage environmental stressors according to cultivation goals. Several factors have been useful in this regard, which at low doses show beneficial eustressing effects (biostimulant/elicitor), while at higher doses, they show distressing toxic effects. These insights highlight biostimulants/elicitors as tools to be included in integrated crop management strategies for reaching sustainability in plant science and agricultural studies. In addition, compelling evidence on the inheritance of elicited traits in plants unfolds the possibility of implementing stressors as a tool in plant breeding.
目前，植物科学基础和应用知识的研究旨在揭示环境因素与基因组相互作用在植物生理学中的作用，以赋予其在气候变化情景下克服挑战的能力。有证据表明，导致环境胁迫（胁迫源）的因素，无论是生物、化学还是物理来源，都会根据剂量在植物中引起良性或不良的影响。后者表明诱导了“适应原效应”现象。可持续作物生产需要更好地了解适应原效应、其基本概念以及输入变量，以使其管理成为可能。这意味着在植物研究中承认适应原效应可以根据种植目标有效管理环境胁迫源，从而确定有益效果。在这方面，有几个因素是有用的，它们在低剂量下表现出良性的良性胁迫效应（生物刺激素/激发子），而在高剂量下则表现出不良的毒性效应。这些见解强调了生物刺激素/激发子作为综合作物管理策略的工具，以实现植物科学和农业研究的可持续性。此外，植物中诱发特性遗传的有力证据表明，将胁迫源作为植物育种的工具具有一定的可能性。
