Abstract：
CONCLUSIONS: Plant Biomarkers are objective indicators of a plant\'s cellular state in response to abiotic and biotic stress factors. They can be explored in crop breeding and engineering to produce stress-tolerant crop species. Global food production safely and sustainably remains a top priority to feed the ever-growing human population, expected to reach 10 billion by 2050. However, abiotic and biotic stress factors negatively impact food production systems, causing between 70 and 100% reduction in crop yield. Understanding the plant stress responses is critical for developing novel crops that can adapt better to various adverse environmental conditions. Using plant biomarkers as measurable indicators of a plant\'s cellular response to external stimuli could serve as early warning signals to detect stresses before severe damage occurs. Plant biomarkers have received considerable attention in the last decade as pre-stress indicators for various economically important food crops. This review discusses some biomarkers associated with abiotic and biotic stress conditions and highlights their importance in developing stress-resilient crops. In addition, we highlighted some factors influencing the expression of biomarkers in crop plants under stress. The information presented in this review would educate plant researchers, breeders, and agronomists on the significance of plant biomarkers in stress biology research, which is essential for improving plant growth and yield toward sustainable food production.
摘要：
结论：植物生物标志物是植物响应非生物和生物胁迫因素的细胞状态的客观指标。可以在作物育种和工程中探索它们以产生耐受胁迫的作物物种。安全和可持续的全球粮食生产仍然是养活不断增长的人口的重中之重。预计到2050年将达到100亿。然而,非生物和生物胁迫因素对食品生产系统产生负面影响，导致作物产量减少70%到100%。了解植物胁迫反应对于开发能够更好地适应各种不利环境条件的新型作物至关重要。使用植物生物标志物作为植物细胞对外部刺激反应的可测量指标，可以作为早期预警信号，在严重损害发生之前检测压力。在过去的十年中，植物生物标志物作为各种经济上重要的粮食作物的应激前指标受到了相当大的关注。这篇综述讨论了一些与非生物和生物胁迫条件相关的生物标志物，并强调了它们在开发抗逆性作物中的重要性。此外,我们强调了在胁迫下影响作物生物标志物表达的一些因素。这篇综述中提供的信息将教育植物研究人员，育种者,和农学家关于植物生物标志物在逆境生物学研究中的意义，这对于改善植物生长和产量以实现可持续粮食生产至关重要。
