Accumulation of beta-carotene during postharvest ripening of nine Thai mango cultivars was assessed after verifying extraction and high-performance liquid chromatographic quantification of the beta-carotene stereoisomers for this sample matrix. No relevant trans-cis isomerization was induced by the analytical procedure. The vitamin A potential of mangoes was evaluated at different ripening stages unequivocally defined by a ripening index (RPIWB). Being rather stable throughout postharvest ripening, the cultivar-specific proportion of cis-beta-carotene isomers ranged from 14 to 40% of the total beta-carotene content. Subjected to the same postharvest ripening conditions, only the cultivars Kaew, Maha Chanok, Chok Anan, and Nam Dokmai #4 developed a bright yellow-orange mesocarp coloration at their fully ripe stage (RPIWB = 1.5-1.8, sugar-acid ratio approximately 50), resulting in total beta-carotene contents of 6544-11249 microg/100 g mesocarp dry weight (DW) and vitamin A values of 892-1573 retinol equivalents (RE)/100 g DW. Contrarily, poor-colored cultivars Mon Duen Gao, Rad, Kiew Sawoei, Okrong Kiew, and Okrong Thong reached total beta-carotene contents of 1019-2195 microg/100 g DW and vitamin A values of 136-298 RE/100 g DW at comparable sugar-acid ratios. Exponential development of mesocarp color (hue angle, H degrees ) and all-trans-beta-carotene levels, respectively, with RPIWB was described for each cultivar, allowing good prediction of mesocarp color and vitamin A value at consumption ripeness.

Understanding the global transcriptomic and metabolic changes during mulberry growth and development is essential for the enhancing fruit quality and optimizing breeding strategies. By integrating phenotypic, metabolomic, and transcriptomic data across 18 developmental and ripening stages of Da10 mulberry fruit, a global map of gene expression and metabolic changes was generated. Analysis revealed a gradual progression of morphological, metabolic, and transcriptional changes throughout the development and ripening phases.

Pitahaya or dragon fruit is an exotic fruit native to Mesoamerica and is cultivated in several regions of the world. In recent years, pitahaya has become increasingly in demand, firstly, for its good nutritional and organoleptic qualities and, secondly, for its richness in antioxidants and bioactive compounds. Spain has opted for new tropical crops, and among them, pitahaya is one of the most planted in recent years.

Gibberellin (GA) is one of the crucial plant hormones involved in fruit ripening regulation. GASA genes, which respond to GA and encode cysteine-rich peptides, are prevalent in plants. While the GASA gene family has been identified in various plants, its role in persimmon fruit ripening remains unclear.

In the background of antioxidation properties of selenium (Se) in plants, the role of nano‑selenium (Se-NPs) was justified in the modulation of Capsicum fruit ripening. In our study, exogenous application of 8 mg L Se-NPs on fruits through 7 days (D) of postharvest storage regulated decay rate, water loss and fruit coat firmness. Se-NPs recovered fruit coat damages with reduction of ion leakage, lipid oxidation, and accumulation of polyamines.

Avocado (Persea americana Mill) is a climacteric fruit harvested at the green stage that ripens postharvest to become edible. The 'Hass' cultivar, known for its rich, buttery flavor and pear-shaped appearance, was studied for metabolite changes during postharvest ripening using UPLC-MS/MS approach. The 16-day ripening period could be divided into three stages: evolution (days 1-9), edible ripe (days 10-15) and overripe (day 16).
