Abstract:
Climate change-induced weather events, such as extreme temperatures, prolonged drought spells, or flooding, pose an enormous risk to crop productivity. Studies on the implications of multiple stresses may vary from those on a single stress. Usually, these stresses coincide, amplifying the extent of collateral damage and contributing to significant financial losses. The breadth of investigations focusing on the response of horticultural crops to a single abiotic stress is immense. However, the tolerance mechanisms of horticultural crops to multiple abiotic stresses remain poorly understood. In this review, we described the most prevalent types of abiotic stresses that occur simultaneously and discussed them in in-depth detail regarding the physiological and molecular responses of horticultural crops. In particular, we discussed the transcriptional, posttranscriptional, and metabolic responses of horticultural crops to multiple abiotic stresses. Strategies to breed multi-stress-resilient lines have been presented. Our manuscript presents an interesting amount of proposed knowledge that could be valuable in generating resilient genotypes for multiple stressors.
摘要:
气候变化引起的天气事件,比如极端温度,长时间的干旱,或洪水,对作物生产力构成巨大风险。对多种应力含义的研究可能与对单一应力的研究有所不同。通常,这些应力重合,扩大附带损害的程度,造成重大财务损失。专注于园艺作物对单一非生物胁迫的反应的调查范围是巨大的。然而,园艺作物对多种非生物胁迫的耐受机制仍然知之甚少。在这次审查中,我们描述了同时发生的最普遍的非生物胁迫类型,并就园艺作物的生理和分子反应进行了深入的详细讨论。特别是,我们讨论了转录,转录后,和园艺作物对多种非生物胁迫的代谢反应。已经提出了培育多应力弹性线的策略。我们的手稿提供了大量有趣的拟议知识,这些知识在为多种压力源生成弹性基因型方面可能很有价值。
