Starch degradation is a necessary process determining banana fruit quality during ripening. Many starch degradation-related genes are well studied. However, the transcriptional regulation of ripening remains poorly understood. In this study, we identified MYB transcription factor (TF) termed MaMYB3, as putative protein binding promoter MaGWD1, member glucan water dikinase (GWD) family which has been demonstrated an important enzyme degradation. MaMYB3 was ripening- and ethylene-repressible,...

Phytohormone abscisic acid (ABA) and plant-specific WRKY transcription factors (TFs) have been implicated to play important roles in various stress responses. The involvement of TFs ABA-mediated cold tolerance economical fruits, such as banana fruit, however remains largely unknown. Here, we reported that ABA application could induce expressions biosynthesis-related genes MaNCED1 MaNCED2, increase endogenous contents, thereby enhance fruit. Four fruit TFs, designated MaWRKY31, MaWRKY33,...

In this study, to investigate the physiological and molecular mechanisms of melatonin inhibiting postharvest rot blueberry fruits, fruits were dipped in 0.3 mmol L −1 solution for 3 min stored at 0°C 80 days. The results indicated that did not significantly ( p > 0.05) inhibit mycelial growth or spore germination Alternaria alternata , Botrytis cinerea Colletotrichum gloeosporioides . addition, an vivo study revealed treatment increased enzymatic activities phenylalanine ammonia lyase...

Linoleic acid (LA; C18:2) and α-linolenic (ALA; C18:3) are two essential unsaturated fatty acids that play indispensable roles in maintaining membrane integrity cold stress, ω-3 desaturases (FADs) responsible for the transformation of LA into ALA. However, how this process is regulated at transcriptional posttranscriptional levels remains largely unknown. In study, an MYB transcription factor, MaMYB4, a banana fruit was identified found to target several MaFADs, including MaFAD3-1, MaFAD3-3,...

Previous studies indicated that methyl jasmonate (MeJA) treatment could effectively reduce the chilling injury of many fruits, including banana, but underlying mechanism is poorly understood. In this study, one lateral organ boundaries (LOB) domain (LBD) gene, designated as MaLBD5, was isolated and characterized from banana fruit. Expression analysis revealed accumulation MaLBD5 induced by cold temperature MeJA treatment. Subcellular localization transactivation assays showed localized to...

Highly prized for its unique taste and appearance, pitaya is a tasty, low-calorie fruit. It has high-water content, high metabolism, susceptibility to pathogens, resulting in an irreversible process of tissue degeneration or quality degradation eventual loss commercial value, leading economic loss. High fruits are key guarantee the healthy development advantages. However, understanding postharvest conservation technology regulation maturation, senescence lacking. To better understand means...

The performance of p-Anisaldehyde (PAA) for preserving pitaya fruit quality and the underpinning regulatory mechanism were investigated in this study. Results showed that PAA treatment significantly reduced decay, weight loss firmness, maintained higher content total soluble solids, betacyanins, betaxanthins, phenolics flavonoids postharvest fruits. Compared with control, increase hydrogen peroxide (H2O2) superoxide anion (O2•-) production was inhibited treated PAA. Meanwhile, improved...

Pitaya fruits have high senescence rates throughout their postharvest storage period. Additionally, studies confirmed that melatonin plays a regulatory role in plant senescence. However, the involvement of remains unclear. In this study, two cultivars pitaya fruit, 'Zihonglong' and 'Jinghonglong', were treated with then evaluated for characteristics while 10 days. The results showed treatment delayed fruit both cultivars, as indicated by inhibition weight loss, decay incidence, relative...

We investigated the effects of melatonin (MT) treatment on physiological quality and cell wall metabolism kiwifruit during a 12-day shelf life period (20 ± 1 °C, 90 5% RH), after days cold storage (0 0.5 RH). Our results showed that MT delayed softening, as evidence by enhanced endurance healthy appearance, quality, color difference L* value, firmness fruit flesh. reduced decay rate, respiration malondialdehyde content; furthermore, MT-treated maintained high levels total soluble solids,...

Melatonin is known to influence various physiological processes, including plant ripening; however, the effect of melatonin on postharvest blueberry fruit softening unknown. Herein, effects at different concentrations (100, 300, and 500 μmol L-1) quality parameters, cell wall substances, cell-wall-degrading enzymes, ultrastructure fruits were investigated during low-temperature storage. treatment was found effectively delay decline in firmness, slow loss soluble solids titratable acids,...

Total phenolic, flavonoid and tannin contents together with antioxidant pro-oxidant activities of Carapa procera were investigated. The activity was evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, ferric reducing/ power (FRAP) method 2,2′-azino bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) assay. study based on the producing iron ion in Fenton reaction. total phenolic content (TPC) extract exhibiting high value 8.2 mg gallic acid equivalents (GAE)/ g dried Carapa. revealed a low...

To determine whether ozone can regulate fruit ripening and delay aging, Kiwifruit (Actinidia deliciosa 'Guichang') was fumigated with different concentrations (100 μL/L, 200 300 μL/L) for 3 h, stored at 1 °C 85 ± 5% RH three months, then matured 20 85% 12 days. Compared controls, the optimal concentration of delayed kiwifruit during cold storage by delaying respiratory burst that precedes decay. Consequently, firmness, nutrient content, enzyme activity remained stable; expression AdACS1...

The inhibitory effects and mechanisms of eugenol were studied in pathogenic fungi that isolated from passion fruit affected with naturally occurring rot; additionally, the effect treatment on rot resistance was investigated. corresponding results demonstrated fungus causing Lasiodiplodia theobromae minimal concentration against L. 0.30 mg/mL. Eugenol significantly inhibited mycelial growth spore germination this fungus. Further, nucleic acid release, electrical conductivity, protein soluble...

Postharvest mango fruit are highly susceptible to rapid ripening, softening and senescence, greatly limiting their distribution. In this study, we evaluated the potential effects of carvacrol (0.06 g L

Decay caused by Neopestalotiopsis clavispora is an important postharvest disease of blueberries that seriously affects the commercial value blueberry fruit.
