Abstract：
Plant responses to abiotic stresses are dynamic, following the unpredictable changes of physical environmental parameters such as temperature, water and nutrients. Physiological and phenotypical responses to stress are intercalated by periods of recovery. An earlier stress can be remembered as \'stress memory\' to mount a response within a generation or transgenerationally. The \'stress priming\' phenomenon allows plants to respond quickly and more robustly to stressors to increase survival, and therefore has significant implications for agriculture. Although evidence for stress memory in various plant species is accumulating, understanding of the mechanisms implicated, especially for crops of agricultural interest, is in its infancy. Rice is a major food crop which is susceptible to abiotic stresses causing constraints on its cultivation and yield globally. Advancing the understanding of the stress response network will thus have a significant impact on rice sustainable production and global food security in the face of climate change. Therefore, this review highlights the effects of priming on rice abiotic stress tolerance and focuses on specific aspects of stress memory, its perpetuation and its regulation at epigenetic, transcriptional, metabolic as well as physiological levels. The open questions and future directions in this exciting research field are also laid out.
摘要：
植物对非生物胁迫的反应是动态的，随着温度等物理环境参数的不可预测变化，水和营养。对胁迫的生理和表型响应由恢复期插入。较早的压力可以被记住为“压力记忆”，以在一代或跨代中进行响应。“压力引发”现象使植物能够对压力源做出更快，更有力的反应，以增加存活率。因此对农业有重大影响。尽管各种植物物种的胁迫记忆证据正在积累，对相关机制的理解，特别是对农业感兴趣的作物，正处于婴儿期。水稻是一种主要的粮食作物，易受非生物胁迫的影响，导致其种植和产量受到全球限制。因此，提高对压力响应网络的理解将对面对气候变化的水稻可持续生产和全球粮食安全产生重大影响。因此,这篇综述强调了启动对水稻非生物胁迫耐受性的影响，并侧重于胁迫记忆的具体方面，它的延续和表观遗传的调节，转录，代谢以及生理水平。还列出了这个令人兴奋的研究领域的开放问题和未来方向。
