Abstract
Fruit composition determines the fruit quality and, consequently, consumer acceptance. As fruit quality can be modified by environmental conditions, it will be impacted by future alterations produced by global warming. Therefore, agricultural activities will be influenced by the changes in climatological conditions in cultivable areas, which could have a high socioeconomic impact if fruit production and quality decline. Currently, different stresses are being applied to several cultivated species to evaluate their impact on fruit metabolism and plant performance. With the use of metabolomic tools, these changes can be precisely measured, allowing us to determine changes in the patterns of individual compounds. As these changes depend on both the stress severity and the specific species involved and even on the specific cultivar, individual analysis must be conducted. To date, the most-studied crops have mainly been crops that are widely cultivated and have a high socioeconomic impact. In the near future, with the development of these metabolomic strategies, their implementation will be extended to other species, which will allow the adaptation of cultivation conditions and the development of varieties with high adaptability to climatological changes.
Highlights
This observation was further corroborated by transcriptomic analyses, which found a reduced glycolytic flux and an increased TCA anaplerosis, which was unfavourable to malic acid accumulation in heated fruits
The increase in arginine can lead to the production of biogenic amines, commonly found in wines, with harmful effects in humans [99]. It is worth highlighting the increase in GABA, as this metabolite acts as a signalling molecule and controls the carbon–nitrogen balance [100,101]
Polyphenols are a heterogeneous group of secondary metabolites derived from the shikimate and phenylpropanoid pathways that are involved in plant relationships with the environment under different stresses [18,47], and it is expected that their contents will be influenced by the abiotic stresses associated with climate change
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. These key climatic change factors are gaining considerable attention in different forums due to the effects on agriculture, which cause important socio-economic losses These abiotic stresses affect plant growth, development, and metabolic processes, reducing the yield and quality of crop plants. Certain cultivars will not be suitable for the areas where they are currently being cultivated, and if climatic conditions drastically change, they will need to be relocated [5] to prevent the crop yield or fruit quality from deteriorating. To avoid this and subsequent dramatic economic losses [6], tolerant and adaptable cultivars with acceptable production and quality must be explored [5,7,8]. In contrast to GC-MS, peak annotation is more difficult since metabolite database are not as rich as GC-MS libraries [32]
