“…For this, as stated by Akhoundnejad et al . (2020), 160 kg N, 50 kg P 2 O 5 , 230 kg K 2 O, 100 kg CaO and 120 kg MgO were applied per hectare. The experiment was carried out under control and drought stress according to a randomised block design with four replications and ten plants in each replication.…”

“…In the parcels where drought was applied, 100% irrigation up to flowering and 50% limited irrigation after flowering have been applied until the yield decrease is minimal, but fruit quality has increased (Patanè & Cosentino, 2010; Patanè et al ., 2011). In the experiment, the amount of irrigation water given to plants with full irrigation in the control application was determined by the following formula (Akhoundnejad et al ., 2020). The drought application has been about half that of water.…”

Tomato fruit has long been regarded as a valuable functional food due to its potential role in the prevention of chronic diseases and thus its positive impacts on human health. In this study, the effect of drought under the climate change threat on increasing antioxidant enzyme activities and non-enzymatic antioxidants in terms of functional food properties of tomato fruits was investigated. Nine drought-tolerant tomato genotypes and two commercial cultivars were grown in an open field that was well watered and exposed to drought stress conditions. The biochemical effects of drought stress in fruit were determined by evaluating the fruits' contents of lipid peroxidation, vitamin C (L-ascorbic acid), total phenols, total flavonoids, lycopene, and beta-carotene and the activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR), total soluble solids and pH. Significant differences (P < 0.05) were found between tomato genotypes in the antioxidant capacity. Antioxidants such as vitamin C, total phenolics, flavonoids, TSS and beta-carotene increased, in tomato fruit under drought. However, pH was slightly decreased. A slight increase in lycopene was observed. The activities of the antioxidative enzymes SOD, CAT, APX and GR were significantly increased in tomato fruit under drought. The increased antioxidant capacity of drought-tolerant tomatoes has been found promising in terms of human nutrition under the threat of climate change.

“…It is of great scientific significance and practical urgency to study the mechanism of heat regulation of plants. The research on plant heat resistance has become a hot research field in agricultural scientific research at home and abroad( Chen, Guo et al,2013;Akhoundnejad, Dasgan, Karabiyik,2020;Ma,2021;Ren,2021 ). However, the research on the response of passion fruit to high-temperature heat damage began relatively late.…”

“…shows that many HSP family genes are highly up-regulated when Cucumis sativus is subjected to high-temperature stress, and AP2, MYB, WRKY, bHLH , and HSF transcription factors show different expression patterns under high-temperature stress( Chen, Han, Ren.2021 ). In addition to conventional crops, the heat tolerance mechanisms of medicinal plants such as Pinellia ternata,Mentha canadensis,and Artemisia annua have also been revealed by transcriptome sequencing ( Lu et al,2018;Da, Li, Gao. 2020;Guo et al,2022 ).…”

High temperature in summer is an unfavorable factor for passion fruit (Passiflora edulis), which can lead to restricted growth, short flowering period, few flower buds, low fruit setting rate, severe fruit drop, and more deformed fruit. To explore the molecular physiology mechanism of passion fruit responding to high-temperature stress, we use Zhuangxiang Mibao, a hybrid passion fruit cultivar, as the test material. Several physiological indicators were measured and compared between high-temperature (average temperature 38℃) and nonmoral temperature (average temperature 25℃) conditions, including photosynthesis, chlorophyll fluorescence parameters, POD, SOD activity and malondialdehyde content. We performed RNA-seq analysis combined with biochemistry experiment to investigate the gene and molecular pathways that respond to high-temperature stress. The results showed that some physiological indicators in the high-temperature group, including the net photosynthetic rate, stomatal conductance, intercellular CO2 concentration, transpiration rate, and the maximum chemical quantum yield of PSⅡ, were significantly lower than those of the control group. Malondialdehyde content was substantially higher than the control group, while superoxide dismutase and superoxide dismutase activities decreased to different degrees. Transcriptome sequencing analysis showed that 140 genes were up-regulated and 75 genes were down-regulated under high-temperature stress. GO and KEGG annotation analysis of differentially expressed genes revealed many metabolic pathways related to high-temperature stress. Further investigation revealed that 30 genes might be related to high-temperature stress, such as CAO, GSH, WRKY, and HSP, which have also been reported in other species. The results of real-time fluorescence quantitative PCR and RNA-seq of randomly selected ten genes are consistent, which suggests that the transcriptome sequencing results were reliable. Our study provides a theoretical basis for the mechanism of passion fruit response to high-temperature stress. Also, it gives a theoretical basis for the subsequent breeding of new heat-resistant passion fruit varieties.

“…Although there are many studies on physiology, plant growth, and yield of tomatoes under high-temperature conditions [21][22][23][24][25][26][27][28], there is limited research [29] on the nutrient and antioxidant content of the fruit affected by high temperatures. Also, there is a growing interest in increasing the antioxidant content of agricultural crops to improve food quality and produce crops with high-stress tolerance.…”

Agriculture is among the sectors that will be impacted first and most by the adverse effects of climate change. Therefore, developing new high-temperature tolerant varieties is an essential economic measure in adaptation to near-future climate change. Likewise, there is a growing interest in increasing the antioxidant content of crops to improve food quality and produce crops with high-stress tolerance. Tomato is the most grown and consumed species in horticultural plants; however, it is vulnerable to 35°C and above high temperatures during cultivation. This study used twenty high-temperature tolerant, two susceptible genotypes, and two commercial tomato varieties in the open field. The experiment was applied under control and high-temperature stress conditions based on a randomized block design with 4 replications and 12 plants per repetition. The study investigated the fruit’s selected quality properties and antioxidant compounds, namely, total soluble solutes (Brix), titratable acidity, pH, electrical conductivity (EC), lycopene, β-carotene, and vitamin C, along with total phenols and total flavonoids under control and stress conditions. As a result, in general, total soluble solutes, titratable acidity, total phenol, and vitamin C contents under high-temperature conditions were determined to increase in tolerant tomato genotypes, while decreases were noted for pH, EC, total flavonoids, lycopene, and β-carotene. However, different specific responses on the basis of genotypes and useful information for breeding studies have been identified. These data on fruit nutrient content and antioxidants will be helpful when breeding tomato varieties to be grown in high-temperature conditions.
