Table grapes are considered non-climacteric fruit, not showing a rapid increase in respiration rate and ethylene production during ripening. Previous research has suggested that abscisic acid (ABA) may have a more crucial role in grape postharvest behaviour. This study aimed to identify biomarkers of postharvest resilience and flavour life of imported table grapes. An experiment was designed to determine i) the role of ABA and catabolites on grape berry senescence; ii) the spatial distribution of these hormones within the grape berry, and iii) the effect of 1-MCP and storage temperature on its postharvest quality. Hence, the use of an ethylene inhibitor, 1-methylcyclopropane (1-MCP), during table grape storage was investigated. Table grapes (Vitis vinifera L.) cv. ‘Krissy’ were subjected to i) control (untreated); and ii) 1-MCP (1 µL L-1; 12 hours; 15°C) and stored under two scenarios: i) 15 days at 0.5°C, followed by five days at 5.5°C to simulate shelf-life; and ii) 20 days at 5.5°C to simulate a higher storage temperature followed by shelf-life. Physiological (i.e. mould incidence, skin colour, firmness, respiration rate) and biochemical analysis (i.e. individual sugars, organic acids, abscisic acid and catabolites) were performed. Grapes subjected to 5.5°C showed significantly higher mould incidence at the end of the shelf-life compared to 0.5°C storage temperature (12.6% vs. 3.1%). Also, and for the first time, the spatial distribution of ABA during the senescence of table grapes was profiled; the distal section had three times more ABA and metabolites than the proximal. We demonstrated that senescence processes were initiated after a significant increase in respiration rate (from 1 to 2.8 mL CO2 kg-1 h-1), and that ABA could be considered a biomarker for table grapes senescence, since an ABA peak preceded the increase in respiration rate, mould incidence, organic acids, and sucrose hydrolysis during postharvest storage; and coincided with a decrease in berry firmness. These findings are of significant importance for the industry as understanding how ABA regulates both senescence processes and quality changes during postharvest cold storage of tables grapes can improve the consistency and reduce waste and consumer complaints.

“…The positive effect of alginate coating with SA or OA, in minimizing loss of antioxidants, might be attributed to delayed oxidation of phenolics and enhanced the antioxidant enzymes. Enhanced of antioxidant in response to preharvest SA or OA application has also been reported in grapes (García-Pastor et al, 2021;Nia et al, 2022). Moreover, alginate coatings, restricted moisture loss and gas exchange, was reported effective in retaining higher antioxidants than control in sweet cherry and mango (Diaz-Mula et al, 2012;Rastegar et al, 2019).…”

“…Since TPC was negatively correlated with weight loss and decay amount, TPC amount was found to be lower in control fruits due to increased weight loss and decay. It has been reported that the application of elicitors such as alginate, SA and OA improves the polyphenol content in fruits and thus increases their quality (Konuk Takma and Korel, 2017;Kok and Bal, 2019;Gomes et al, 2021;García-Pastor et al, 2021). These results indicate that SA and OA applications promoted TPC accumulation during storage due to activation of PAL, a key enzyme of the phenylpropanoid pathway (Shen and Yang, 2017;Martinez-Espla et al, 2019).…”

“…At the end of the 60-day storage period, berries treated with Alg+SA and Alg+OA maintained firmness levels of 462 and 429 g, respectively, while the control and Alginate had a firmness of 390 and 371 g. Higher retention of firmness applied with SA and OA enriched alginate coating may be due to lower activity of enzymes in the cell wall, resulting in a slower degradation rate. Similarly, delaying the softening process during storage have been also obtained after SA and OA applications in grape (Champa et al, 2014;Garcia-Pastor et al, 2021). SSC, TA and Ripening Index SSC, TA and ripening index are basic indicators reflecting the organoleptic quality of table grapes.…”

This study aimed to evaluate the synergistic effect of preharvest spraying with alginate and in combination with salicylic acid (SA) and oxalic acid (OA), on the quality parameters and storage life of ‘Red Globe’ grape variety at 0-1°C with 85-90% relative humidity for 60 days. Data of physical and chemical quality parameters were taken at 15-day intervals. The results have shown that alginate coatings delayed changes in weight loss, firmness and berry color compared to control. Grapes coated alginate enriched with oxalic acid and salicylic acid proved to the most effective applications in restricting stem browning and decay incidence. Moreover, these formulations improved the content of phenolic compounds, contributing to the high antioxidant potential of coated grapes. These findings reveal that preharvest sprayed clusters with alginate combined with SA and OA applications may have high potential for improving storage quality of commercial grape.

“…In plants, 9-cis-epoxycarotenoid dioxygenase (NCED) function as a pivotal enzyme in abscisic acid (ABA) biosynthesis and can drive the specific cleavage of 9-cis-epoxycarotenoids to produce the essential ABA precursor, xanthoxin [4][5][6]. Long-term studies have shown that the endogenous hormone abscisic acid (ABA) is intricately linked to regulating drought resistance in some plants [7][8][9][10][11][12].…”

Peanut (Arachis hypogaea L.) is an important crop that provides essential proteins and oils for human and animal consumption. 9-cis-epoxycarotenoid dioxygenase (NCED) have been found can play a vital role in abscisic acid (ABA) biosynthesis and may be a response to drought stress. Until now, in Arachis hypogaea, no information about the NCED gene family has been reported and the importance of NCED-related drought tolerance is unclear. In this study, eight NCED genes in Arachis hypogaea, referred to as AhNCEDs, are distributed across eight chromosomes, with duplication events in AhNCED1 and AhNCED2, AhNCED3 and AhNCED4, and AhNCED6 and AhNCED7. Comparative analysis revealed that NCED genes are highly conserved among plant species, including Pisum sativum, Phaseolus vulgaris, Glycine max, Arabidopsis thaliana, Gossypium hirsutum, and Oryza sativa. Further promoter analysis showed AhNCEDs have ABA-related and drought-inducible elements. The phenotyping of Arachis hypogaea cultivars NH5 and FH18 demonstrated that NH5 is drought-tolerant and FH18 is drought-sensitive. Transcriptome expression analysis revealed the differential regulation of AhNCEDs expression in both NH5 and FH18 cultivars under drought stress. Furthermore, compared to the Arachis hypogaea cultivar FH18, the NH5 exhibited a significant upregulation of AhNCED1/2 expression under drought. To sum up, this study provides an insight into the drought-related AhNCED genes, screened out the potential candidates to regulate drought tolerance and ABA biosynthesis in Arachis hypogaea.
