“…Ripening is a normal process during fruit maturation. Several biochemical and physiological changes occur, such as those involving flavor, color, aroma, and texture, and there are also increases in ethylene production and respiration [16,55]. Ethylene is an important plant hormone for fruit ripening, triggering climacteric fruit ripening [56].…”

Fruits are important horticultural commodities because they provide nutrients that help human health. Fruits are mostly consumed as fresh products; however, there are challenges in retaining the freshness, such as the rapid ripening process that triggers fruit deterioration and reduces fruit quality and nutrient content. The postharvest quality of horticultural crops is affected by pre-and postharvest treatment. Most farmers use chemical compounds and fungicides to prevent postharvest damage; however, this results in health hazards and environmental pollution. Melatonin can be used for maintaining and improving postharvest horticultural crops such as fruits. Melatonin is a new bioactive compound that is a potent free radical scavenger and antioxidant. It has been studied as an alternative to harmful chemicals used commercially in the postharvest management of fresh products. For human health, melatonin plays a regulatory role in circadian and seasonal rhythms, sleep, retinal functions, and the immune system. In plants, melatonin regulates many biological processes, particularly when plants have experienced abiotic stress, germination, aging, and growth. The effect of exogenous melatonin on fruit ripening has focused primarily on the relationship between melatonin and ethylene plant hormones. Many studies in recent years have discussed melatonin’s role in plants, particularly in delaying plant aging as an alternative way of increasing fruit shelf life. This review provides a comprehensive overview of melatonin biosynthesis in plants, factors that affect the content of melatonin in fruit, melatonin mechanisms in fruit ripening, the impact of melatonin on postharvest fruit quality, the effect of melatonin on postharvest quality, and the change in metabolite content of horticultural products, particularly fruits.

“…However, many studies have also reported that tomato varieties from mutations or mutant tomatoes are generally less tasty than local varieties. An example of a mutant tomato is Sletr12 tomatoes produced from the Micro-Tom library, which can delay the normal ripening process (Okabe et al, 2012) and decrease the susceptibility to ethylene (Mubarok et al, 2019). Sletr11 along with Sletr12, are the novel mutant alleles which are isolated from an ethylene receptor gene, Solanum lycopersicum ETHYLENE RESPONSE 1 (SlETR1), taken from a Micro-Tom Library mutant population (Okabe et al, 2011).…”

Tomatoes are climacteric fruits that experience a surge in respiration rate and ethylene production. This condition affects the fruits’ physiological deterioration, shortens their shelf-life, and degrades the quality of tomatoes. The study aimed to enhance the shelf-life of commercial tomatoes with different genetic backgrounds by utilizing the Sletr1-2 mutant, which has a lower sensitivity to ethylene. A randomized block design (RBD) was applied to achieve this goal, where 12 different plant genotypes were considered as treatments, and each treatment was replicated four times. The results showed that fruit shelf-life was extended by crossing commercial tomatoes with Sletr1-2 mutant tomatoes. Genetic variability for all shelf-life characteristics were narrow. In contrast, there were broad phenotypic variability for fruit hardness and weight loss characteristics.

“…Tomato (Solanum lycopersicum) is an essential Solanaceae horticultural commodity in the world (Anas et al, 2022). Tomatoes are generally used as a source of nutrients and antioxidants, such as vitamins A, C and B, calcium, potassium, magnesium, sodium, iron, phenolic antioxidants, flavonoids, lycopene and ascorbic acid (Oboulbiga et al, 2017;Mubarok et al, 2019a;Mubarok et al, 2023). Tomato production is affected by several factors, such as genetics, nutrition and cultivation methods and environmental factors, including temperature.…”

Fruit set is one of the main problems that arise in tomato plants under heat-stress conditions, which disrupt pollen development, resulting in decreased pollen fertility. Parthenocarpic tomatoes can be used to increase plant productivity during failure of the fertilisation process under heat-stress conditions. The aim of this study were to identify the plant adaptability and fruiting capability of ?iaa9-3 and iaa9-5 tomato mutants under heat-stress conditions. The iaa9-3 and iaa9-5 and wild-type Micro-Tom (WT-MT) plants were cultivated under two temperature conditions: normal and heat-stress conditions during plant growth. The results showed that under the heat-stress condition, iaa9-3 and iaa9-5 showed delayed flowering time, increased number of flowers, and increased fruit set and produced normal-sized fruit. However, WT-MT cannot produce fruits under heat stress. The mutants can grow under heat-stress conditions, as indicated by the lower electrolyte leakage and H2O2 concentration and higher antioxidant activities compared with WT-MT under heat-stress conditions. These results suggest that iaa9-3 and iaa9-5 can be valuable genetic resources for the development of tomatoes in high-temperature environmental conditions.
