Fucoidan, the complex fucose-containing sulphated polysaccharide varies considerably in structure, composition, and bioactivity, depending on source, species, seasonality, extraction method. In this study, we examined five fucoidans extracted from same seaweed species
As a natural antimicrobial agent, Melaleuca alternifolia oil (MAO) is generally recognized to be safe and effective in the inhibition of phytopathogenic fungi. Due lack comprehensive studies on MAO for controlling postharvest Aspergillus, we investigated preservative mechanism its components against Aspergillus ochraceus grapes evaluate their potential effectiveness as fruit preservatives.In our study, compositions were analysed by gas chromatography-mass spectrometry. The inhibitory effects...
Resveratrol dimers belong to a group of compounds called stilbenes, which along with proanthocyanidins, anthocyanins, catechins, and flavonols are natural phenolic found in grapes red wine. Stilbenes have variety structural isomers, all exhibit various biological properties. Counter-current chromatography two-phase solvent system composed n-hexane/ethyl acetate/methanol/water (2:5:4:5, v/v/v/v) was applied isolate purify stilbene from the stems wine grape. Two isomers resveratrol...
Fucoidan, a sulfated polysaccharide extracted from brown seaweeds, has been shown to possess various antioxidant, anticoagulant, antiviral, and anticancer functions. In this study, we focused on low molecular weight fucoidan (LMWF) which was New Zealand Undaria pinnatifida, investigated its anti-proliferative effects, combined with quadruplex-forming oligonucleotide aptamer (GroA, AS1411), powerful cell surface Nucleolin inhibitor, in prostate cancer cells. We examined LMWF (<10 kDa)...
Pterostilbene controlled the growth of Geotrichum citri-aurantii effectively through experiments arthroconidium germination on agar plate, which displayed a strong antifungal activity. Observations using light microscope, scanning electron showed that morphology and inner structure G. treated with pterostilbene changed notably. Some cells were abnormal or lysed. In order to further clarify molecular mechanism action, we examined binding properties exerted by DNA RNA fungal cells. Results...
Aspergillus aculeatus, a pathogen of peaches, can cause soft rot and lead to economic losses in agricultural production. However, studies on the prevention caused by A. aculeatus have rarely been reported. Tricyclazole (TCZ) is fungicide that has widely used disease various crops but inhibitory mechanism TCZ unknown. Our aim was determine effects aculeatus. In our study, inhibited growth fungal colonies when applied at 0·5–6 mmol l−1 production melanin 3 l−1. Conidia exposed were less...
Pathogenesis-related protein 5 (PR5) is encoded by the host and related to resistance biological abiotic factors. In present study, we constructed interference expression vector pBIA-LePR5-RNAi analyzed of transgenic tomatoes Alternaria alternata (A. alternata). To understand regulatory mechanism LePR5 gene, green fluorescent fluorescence cellular localization promoter functional elements were investigated. Results showed that gene declined, morbidity was significantly higher than...
Stilbenes, particularly resveratrol and dimers, could effectively quench singlet oxygen (1O2). It was reported that both resorcinol carbon-carbon double bond quenching 1O2 can participate in the mechanism. However, it is still not clear which structure plays a dominant role 1O2. To investigate characteristic mechanism of 1O2, resveratrol, pterostilbene piceatannol abilities were compared by UHPLC-QTOF-MS2 UHPLC-QQQ-MS2. Results showed catechol, participated Catechol ring leading mechanism,...
Genetic manipulation of antagonists shows tremendous potential for improving biocontrol activity antagonists. Here, bivalent antibacterial peptide Cecropin A/PsdI gene was transformed and expressed in methylotrophic yeast, Pichia pastoris GS115. The yeast GS115/CEC-PSD showed a great ability delaying sour rot citrus fruit based on observations restrained growth geminated Geotrichum citri-aurantii spores relative to non-transformed strain. Although there no remarkable discrepancy between...
Sour rot is a leading disease of citrus fruit caused by the postharvest pathogen Geotrichum citri-aurantii. It has been reported that essential oils can be used as substitutes for synthetic fungicides to control pathogen. In this study, changes in metabolites and antifungal effects G. citri-aurantii treated with peppermint oil (PO) were investigated. The inhibition rate mycelial growth increased PO concentration increased, 6 μl PO/disk resulted radial 79.2%. electrical conductivity compared...
Resveratrol dimers have been extensively reported on due to their antioxidative activity. Previous studies revealed that resveratrol dimer has shown selectively quench singlet oxygen (1O2), and could protect DNA from oxidative damage. The mechanism of protecting against damage is still not clear. Therefore, in this project, the reactants products guanine were qualitatively monitored quantitatively analyzed by UHPLC-QTOF-MS2 UHPLC-QQQ-MS2. Results showed when attacked 1O2, mostly oxidized,...
Sour rot, caused by Geotrichum citriaurantii (G. citri-aurantii.), is one of the most serious grapevine secondary infection diseases in China. We have determined that pterostilbene, important phytoalexin, effectively inhibits activity G. citri-aurantii. To study synthesis mechanism pterostilbene against citri-aurantii grape, we initially detected content present grapes infected with use UHPLC-QQQ-MS2. Pterostilbene levels are controlled resveratrol O-methyltransferase (ROMT) gene, and within...
