Epigenetics for Climate-Smart and Sustainable Agriculture, Jen-Tsung Chen, Editör, CAB International , Oxford, ss.519-535, 2025
Plant stress priming, characterized by brief exposure to mild stress conditions, induces the formation of stress memory in plants. This memory equips them to respond more effectively when faced with recurrent stressors, as if the plant had learned from previous experiences. The effects of this priming process are far-reaching and often visible at the genetic and epigenetic levels. Epigenetic mechanisms lead to shifts in gene expression and the appearance of variances in transcript levels, enabling the plant to fine-tune its response to future stressors. Crucially, stress memory is linked to epigenetic modifications, and these changes can sometimes be limited to the recovery process, while in other instances, they are inherited across generations. The formation of stress memory gives plants plasticity and increases their chances of adaptation to environmental stimuli. This chapter discusses the relationship between plant stress priming and epigenetic mechanisms, with diverse examples. However, the molecular mechanisms of priming are not fully elucidated and are waiting to be discovered, since it is important in terms of developing new strategies for the sustainability of agriculture and food safety in the coming years.
