“…It functions in different phases of the plant’s life cycle, such as seed germination, expansion of leaves, blossoming, setting of fruits, and their subsequent growth [ 25 , 26 ]. Hence, numerous studies have investigated the effects of GA on seed development and fruit growth [ 27 ]. It has been demonstrated that the utilization of GA can improve the firmness of tomato fruits by augmenting the concentrations of ascorbic acid, soluble solids, and fruit weight [ 28 , 29 ].…”

In tomato (Solanum lycopersicum), the ripening of fruit is regulated by the selective expression of ripening-related genes, and this procedure is controlled by transcription factors (TFs). In the various plant-specific TF families, the no apical meristem (NAM), Arabidopsis thaliana activating factor 1/2 (ATAF1/2), and cup-shaped cotyledon 2 (CUC2; NAC) TF family stands out and plays a significant function in plant physiological activities, such as fruit ripening (FR). Despite the numerous genes of NAC found in the tomato genome, limited information is available on the effects of NAC members on FR, and there is also a lack of studies on their target genes. In this research, we focus on SlNAP1, which is a NAC TF that positively influences the FR of tomato. By employing CRISPR/Cas9 technology, compared with the wild type (WT), we generated slnap1 mutants and observed a delay in the ethylene production and color change of fruits. We employed the yeast one-hybrid (Y1H) and dual-luciferase reporter (DLR) assays to confirm that SlNAP1 directly binds to the promoters of two crucial genes involved in gibberellin (GA) degradation, namely SlGA2ox1 and SlGA2ox5, thus activating their expression. Furthermore, through a yeast two-hybrid (Y2H), bimolecular fluorescence complementation (BIFC) and luciferase (LUC) assays, we established an interaction between SlNAP1 and SlGID1. Hence, our findings suggest that SlNAP1 regulates FR positively by activating the GA degradation genes directly. Additionally, the interaction between SlNAP1 and SlGID1 may play a role in SlNAP1-induced FR. Overall, our study provides important insights into the molecular mechanisms through which NAC TFs regulate tomato FR via the GA pathway.

“…In addition, some preharvest treatments, such as spraying with foliar fertilizers and growth regulators, have been investigated. Preharvest spraying of blueberries, peaches, apricots, noni (Morinda citrifolia L.), grapes, and apples with gibberellins, selenium, calcium chloride, and boric acid delayed postharvest oxidative senescence, improved resistance and quality during storage, and extended shelf-life [6][7][8][9][10][11][12].…”

Panzao (Ziziphus jujuba Mill. cv. ‘Jingcang1’) have a short shelf-life, which hampers their marketability. To investigate effects of combined pre- and postharvest treatments on quality and softening during storage, preharvest Guomantian foliar fertilizer (FF) spray and postharvest salicylic acid (SA) dip were applied to panzao. By day 63 of storage, fruit firmness responded to treatment in the order of FF+SA treatment > FF or SA treatments > Control. All treatments inhibited fruit reddening during storage and, compared with those of the control, alleviated the decline in total soluble solids, ascorbic acid, and phenol contents and decreased the oxidative aging process, which was consistent with the change in firmness. The FF+SA treatment reduced the activities of amylase, cellulase, polygalacturonase, and β-glucosidase, which decreased the degradation of macromolecules including starch, cellulose, and pectin. Principal component analysis showed that FF+SA exhibited a synergistic effect and was the most effective treatment for maintaining fruit quality during storage. FF increased accumulation of nutrients during growth and improved quality, while SA delayed the decline in fruit quality and reduced softening. These results provide the theoretical basis and technical knowledge for improving the shelf-life of panzao during storage and long-distance transportation.

Putrescine (Put), gibberellic acid (GA3), and salicylic acid (SA) are involved in improving fruit growth and development. This is the first study investigating the effect of 1 mM Put, 100 mg L-1 GA3, and 100 mg L-1 SA on Phoenix dactylifera, cv. Zaghloul fruits. The experiment was conducted in a completely randomized block design during two successive seasons and five treatments [control (distilled water spray), Put, Put + GA3, Put + SA, and Put + GA3 + SA] were sprayed at the Hababouk (cell division) stage and Kimri [unripe green (cell elongation)] stage. Our results showed that all treatments significantly improved the yield and quality of ‘Zaghloul’ fruit by increasing the dry matter, crude fiber, ash, total soluble solids, (reducing, non-reducing, and total soluble) sugars, carbohydrate, protein, nitrogen, phosphorus, potassium, calcium, magnesium, sodium, zinc, iron, and manganese content as well as the peroxidase and catalase activity. Compared with the control treatment, exogenous applications also enhanced the amino acid (glutamic acid, aspartic acid, proline, glycine, alanine, arginine, cysteine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, serine, threonine, tyrosine, valine) acquisition and phytohormone (indole-3-acetic acid, cytokinins, GA3, SA) content, while decreasing the percentage of moisture, total acidity, total phenols, and tannins. The novel evidence indicates that among all treatments, application of diamine (Put), in combination with phytohormones (GA3 and SA), has the greatest effect on improving ‘Zaghloul’ fruit yield by up-regulating the nutrient acquisition, sugar accumulation, amino acid profile, antioxidant response, and phytohormone performance. These findings support the use of Put in conjunction with GA3 and SA to improve fruit yield and quality.
