“…Banana peel tissues were collected, frozen with liquid nitrogen and smashed into powder with a pulverizer, respectively. Polysaccharides were extracted by the method of John et al [47] with some modification. Briefly, 100 g of power from twelve banana fingers was homogenized with 1 L of distilled water and then incubated at 105 °C for 2 h. The extract was filtered through gauze and then concentrated by a vacuum rotary evaporator (Eyela N1100 V-W, Tokyo Rikakikai Co. Ltd., Tokyo, Japan).…”

Fusarium proliferatum can infect many crops and then produce fumonisins that are very harmful to humans and animals. Previous study indicates that carbon sources play important roles in regulating the fumonisin biosynthesis. Unfortunately, there is limited information on the effects of carbon starvation in comparison with the carbon sources present in the host of fumonisin production in F. proliferatum. Our results indicated that F. proliferatum cultivated in the Czapek’s broth (CB) medium in the absence of sucrose could greatly induce production of fumonisin, while an additional supplementation of sucrose to the culture medium significantly reduced the fumonisin production. Furthermore, cellulose and hemicellulose, and polysaccharide extracted from banana peel, which replaced sucrose as the carbon source, can reduce the production of fumonisin by F. proliferatum. Further work showed that these genes related to the synthesis of fumonisin, such as FUM1 and FUM8, were significantly up-regulated in the culture medium in the absence of sucrose. Consistent with fumonisin production, the expressions of FUM gene cluster and ZFR1 gene decreased after the addition of sucrose. Moreover, these genes were also significantly down-regulated in the presence of cellulose, hemicellulose or polysaccharide extracted from peel. Altogether, our results suggested that fumonisin production was regulated in F. proliferatum in response to different carbon source conditions, and this regulation might be mainly via the transcriptional level. Future work on these expressions of the fumonisin biosynthesis-related genes is needed to further clarify the response under different carbon conditions during the infection of F. proliferatum on banana fruit hosts. The findings in this study will provide a new clue regarding the biological effect of the fumonisin production in response to environmental stress.

“…Inevitably, under the temperature change, the respiration and transpiration of sweet cherry are affected signicantly, causing the loss of water, the reduction of cell turgor and the degradation of the cell wall, which eventually leads to the fruit soening. [46][47][48][49] In addition, the rmness of postharvest sweet cherry correlated more positively and signicantly with the content of pectin, as the skeleton material of cell wall, especially SSP. 14,15 The SSP constant in the TF and CT-5 groups decreased as time progressed and levelled out at storage day 16, tending to remain stable during subsequent storage.…”

“…As shown in Figure 3(A), The FT-IR spectra of TAPS and OSPS displayed a broad peak at 3366 and 3419 cm −1 , respectively, which was attributed to the stretching vibration of O-H (W. Liu et al, 2016;. The peaks at 2930 and 1411 cm −1 were due to the C-H stretching vibration and variable angle vibration respectively (John et al, 2018;Molaei & Jahanbin, 2018;. The peaks at 1651 cm −1 in TAPS spectrum and 1659 cm −1 in OSPS spectrum were the characteristic of bound water (W. Liu et al, 2016;Molaei & Jahanbin, 2018).…”

Polysaccharides have various bioactivities including anti-tumour, antioxidant and immunoregulation, which are correlated with their structural characteristics. Here, four polysaccharides from Glycyrrhiza uralensis (GUPS), Pleurotus ferulae (PFPS), Triticum aestivum (TAPS) and Oryza sativa (OSPS) were purified to compare their structural characteristics and immunoregulatory activities. The data showed that TAPS, OSPS, GUPS and PFPS contained different monosaccharide components and had distinctly structural characteristics. All the four polysaccharides promoted the maturation of dendritic cells (DCs) through TLR4 with different activities. GUPS and PFPS also reduced the phagocytosis of DCs but not for TAPS and OSPS. Importantly, GUPS and PFPS enhanced the Th1 skewing immune response in mice without inflammation.TAPS and OSPS only showed weak immunostimulatory activity in vivo. The immunostimulatory activities of the four polysaccharides were ranked as PFPS = GUPS > TAPS > OSPS. ARTICLE HISTORY
