Abstract

Recent research has extensively covered the effects of climate change factors, such as elevated CO2, rising temperatures and water deficit, on grapevine (Vitis spp.) biology. However, the assessment of the impacts of multiple climate change-related stresses on this crop remains complex due to the large number of interactive effects among environmental factors and the regulatory mechanisms that underlie these effects. Consequently, there is a substantial discrepancy between the number of studies conducted with a single or two factors simultaneously, and those with a more holistic approach. This review focuses on how climate change factors will coexist across the viticultural areas of the globe and summarises the main interactive mechanisms affecting crop performance. We highlight how the rise in temperatures will be enhanced when dealing with specific periods, such as the ripening months. Changes in crop phenology in response to temperature have been a major focus of most studies. However, how these physiological shifts may result in deleterious effects on yield and quality deserves further research. Rising temperatures will most certainly continue to represent the most imminent threat to viticulture due to its effects on grape phenology, composition and crop water requirements. Nevertheless, elevated CO2 may offer some relief through increased water use efficiency, as recent studies have shown. Within the repertoire of regulatory mechanisms that plants possess, hormones play a major role explaining the effects of combined stresses due to their crosstalk. In fact, growth regulators fine tune stress responses depending on the multiple stresses present. The paper focuses on the multistress responses mediated by ABA and jasmonate, and on the intricate interconnections of signalling among the different plant hormones.

了解葡萄对气候变化的反应:多胁迫和整体方法。
最近的研究广泛涉及气候变化因素(如二氧化碳升高、气温升高和缺水)对葡萄生物学的影响。然而,由于环境因素之间存在大量的交互影响以及这些影响背后的调控机制,评估与气候变化相关的多种胁迫对这种作物的影响仍然十分复杂。因此,同时针对单个或两个因素进行的研究数量与采用更全面方法进行的研究数量之间存在巨大差异。本综述重点探讨气候变化因素将如何在全球葡萄栽培地区共存,并总结影响作物表现的主要互动机制。我们强调了在特定时期,如成熟期,气温的升高将如何得到加强。作物物候对温度的反应变化是大多数研究的重点。然而,这些生理变化如何对产量和质量产生有害影响,值得进一步研究。由于气温升高对葡萄物候、成分和作物需水量的影响,气温升高无疑将继续对葡萄栽培构成最紧迫的威胁。然而,正如最近的研究表明的那样,升高的二氧化碳可以通过提高水分利用效率来缓解这一问题。在植物所拥有的一系列调节机制中,激素因其相互影响而在解释综合胁迫效应方面发挥着重要作用。事实上,生长调节剂会根据多重胁迫的情况对胁迫反应进行微调。本文重点介绍了由 ABA 和茉莉酸介导的多重胁迫反应,以及不同植物激素之间错综复杂的相互联系。

期刊介绍: The Journal of Experimental Botany publishes high-quality primary research and review papers in the plant sciences. These papers cover a range of disciplines from molecular and cellular physiology and biochemistry through whole plant physiology to community physiology. Full-length primary papers should contribute to our understanding of how plants develop and function, and should provide new insights into biological processes. The journal will not publish purely descriptive papers or papers that report a well-known process in a species in which the process has not been identified previously. Articles should be concise and generally limited to 10 printed pages.
