Abstract:
The tomato is a fruit vegetable rich in nutritional and medicinal value grown in greenhouses and fields worldwide. It is severely sensitive to heat stress, which frequently occurs with rising global warming. Predictions indicate a 0.2 °C increase in average surface temperatures per decade for the next three decades, which underlines the threat of austere heat stress in the future. Previous studies have reported that heat stress adversely affects tomato growth, limits nutrient availability, hammers photosynthesis, disrupts reproduction, denatures proteins, upsets signaling pathways, and damages cell membranes. The overproduction of reactive oxygen species in response to heat stress is toxic to tomato plants. The negative consequences of heat stress on the tomato have been the focus of much investigation, resulting in the emergence of several therapeutic interventions. However, a considerable distance remains to be covered to develop tomato varieties that are tolerant to current heat stress and durable in the perspective of increasing global warming. This current review provides a critical analysis of the heat stress consequences on the tomato in the context of global warming, its innate response to heat stress, and the elucidation of domains characterized by a scarcity of knowledge, along with potential avenues for enhancing sustainable tolerance against heat stress through the involvement of diverse advanced technologies. The particular mechanism underlying thermotolerance remains indeterminate and requires further elucidatory investigation. The precise roles and interplay of signaling pathways in response to heat stress remain unresolved. The etiology of tomato plants\' physiological and molecular responses against heat stress remains unexplained. Utilizing modern functional genomics techniques, including transcriptomics, proteomics, and metabolomics, can assist in identifying potential candidate proteins, metabolites, genes, gene networks, and signaling pathways contributing to tomato stress tolerance. Improving tomato tolerance against heat stress urges a comprehensive and combined strategy including modern techniques, the latest apparatuses, speedy breeding, physiology, and molecular markers to regulate their physiological, molecular, and biochemical reactions.
摘要:
番茄是一种富含营养和药用价值的水果蔬菜,生长在世界各地的温室和田地。它对热应激非常敏感,这经常发生在全球变暖加剧的情况下。预测表明,在接下来的三十年中,平均表面温度每十年增加0.2°C,这突显了未来严峻的热应力的威胁。以前的研究报告说,热胁迫对番茄生长产生不利影响,限制了营养素的可用性,锤子光合作用,扰乱繁殖,变性蛋白质,扰乱信号通路,并损伤细胞膜。响应于热胁迫的活性氧的过量产生对番茄植物是有毒的。热应激对番茄的负面影响一直是许多研究的焦点,导致了几种治疗干预措施的出现。然而,从全球变暖加剧的角度来看,开发能够耐受当前热应激和耐久的番茄品种还有相当大的距离。这篇综述提供了在全球变暖背景下对番茄热应激后果的批判性分析,它对热应激的先天反应,以及以知识稀缺为特征的领域的阐明,以及通过各种先进技术的参与来增强对热应力的可持续耐受性的潜在途径。耐热性的特定机制仍然不确定,需要进一步阐明研究。信号通路在热应激反应中的确切作用和相互作用仍未解决。番茄植物对热胁迫的生理和分子反应的病因仍无法解释。利用现代功能基因组学技术,包括转录组学,蛋白质组学,和代谢组学,可以帮助识别潜在的候选蛋白,代谢物,基因,基因网络,和促进番茄胁迫耐受性的信号通路。提高番茄对热胁迫的耐受性需要采取包括现代技术在内的综合策略,最新的仪器,快速繁殖,生理学,和分子标记来调节它们的生理,分子,和生化反应。
