“…Correlation analysis showed that the lignin content, cellulose content, and SP content were negatively correlated with firmness, while propectin content, PG activity, and, Cx activity, were positively correlated with it (Figure 5). Similar result was also observed by Huang et al (2022) that the hardness was related to SP content. A significant negative correlation between cellulose content and Cx activity was observed, and the correlation coefficient is −0.98 and −0.94 for control group and 9 µl L −1 ozone treated group, respectively (Figure 5).…”

Ozone treatment is a useful approach to maintain postharvest quality for various fruits and vegetables. In this study, the effects of ozone fumigation on lignification and postharvest quality changes in water bamboo shoots were investigated. Water bamboo shoots were respectively treated with ozone at the concentrations of 0 (control), 3, 6, 9, and 12 µl L −1 , packaged in polyethylene packing bag and stored at 2 ± 1°C for 60 days. The results showed that ozone treatment maintained the lightness, whiteness index values and retarded the lignification during storage. Water bamboo shoots treated with 9 µl L −1 ozone showed the best fruit quality and the least lignification. Ozone treatment also slowed the decrease of soluble pectin content and cellulose accumulation by inhibiting the activities of cellulase (Cx) and polygalacturonase. In addition, ozone treatment also protected cell ultrastructure. Ozone treatment could be a potential alternative for inhibiting lignification and delaying quality deterioration of water bamboo shoots during storage.

“…Contrary to the propectin content, the SP accumulated during the storage, and ozone treatment could impede the increase in water bamboo shoots (Figure 2D). The accumulation of SP might due to the hydrolysis of propectin, which was consistent with the previous results (Huang et al, 2022).…”

“…However, the long-term continuous planting of water oat can lead to the accumulation of pathogenic bacteria, which causes a decrease in the quality of water oat and soil [3]. The existing studies on water oat mostly focus on its yield, quality, storage, and nutritional and healthcare values [2,4] but rarely explore whether the long-term planting of water oat would cause soil degradation and change the soil microbial structures. In this context, studying the changes in the soil environment of water oat with different planting years is of great significance for understanding and evaluating the effect of water oat on soil quality and the sustainable development of water oat.…”

As an cultivated aquatic vegetable, the long-term continuous monocropping of water oat results in the frequent occurrence of diseases, the deterioration of ecological system and decreased quality of water oat. In this study, real-time quantitative PCR (qPCR) and Illumina high-throughput sequencing were used to determine the dynamic changes in bacterial and fungal communities in rhizosphere soil under continuous cropping of water oat for 1, 5, 10, 15 and 20 years (Y1, Y5, Y10, Y15 and Y20), and soil properties and enzyme activities were also determined. Results showed that the contents of soil organic carbon (SOC), total nitrogen (TN), alkali-hydrolyzable nitrogen (AN), available phosphorus (AP) and the activities of four soil enzymes increased in Y5 and Y10 and then decreased in Y15 and Y20. Spearman correlation analysis identified SOC, TN, AP and AN as the main factors that affect the four enzyme activities. The qPCR results showed that there was no significant difference in bacterial abundance between the different planting years, while the fungal abundance first increased and then decreased. The long-term continuous planting of water oat (Y15 and Y20) significantly reduced the operational taxonomic unit numbers and the Shannon, Chao1, and ACE indices of rhizosphere bacteria and fungi. The bacterial and fungal community compositions were markedly affected by the continuous planting year. The relative abundances of Bacteroidetes and Firmicutes decreased significantly in Y10 and Bacteroidetes increased significantly in Y15. Relative abundances of dominated Mortierellomycota and Ascomycota phyla increased with the continuous cropping years, while Rozellomycota presented the opposite trend. The AK, AN, and SOC were the main factors that changed the bacterial community, while AK and AP significantly shifted the fungal community. Thus, long-term continuous planting of water oat resulted in the deterioration of soil nutrients and microbial communities. The results provided a reference for the remediation of soil under continuous water oat planting and sustainable development of water oat industry.

“…Softening is a typical ripening feature of banana fruit, mainly brought by the structural breakdown of cell walls, particularly the breakdown of components of polysaccharide compositions including pectin, cellulose and hemicellulose (Vorwerk et al ., 2004). In plant cell walls, pectin covalently combines with cellulose and hemicellulose to form a protective network, which maintains the morphology and integrity of the cell wall (Huang et al ., 2022). In our study, the contents of HSP, NSP, cellulose and hemicellulose decreased to varying degrees over storage, while the content of WSP increased, showing that the softening of banana fruit correlated with the conversion of water‐insoluble pectin to WSP.…”

SummaryAbstractHarvested banana undergoes rapid softening, which limits its shelf life. To delay softening, banana fruit were treated with hydrogen sulfide (H2S) emitted by 0.6 mM sodium hydrosulfide (NaHS) and stored at 15°C for 16 days. The effects of H2S on cell wall degradation and other physiological characteristics were investigated. In comparison to control fruits, H2S‐treated bananas retained a higher level of fruit firmness, but lower hue values. Ethylene metabolism analysis suggested that H2S inhibited the production of ethylene and the accumulation of 1‐aminocyclopropane‐1‐carboxylic acid (ACC), and decreased the activities of ACC synthase (ACS) and ACC oxidase (ACO). Cell wall polysaccharides determination assays suggested that H2S‐treatment increased the proportion of HCl‐soluble pectin (HSP), NaOH‐soluble pectin (NSP), cellulose, and hemicellulose, but decreased water‐soluble pectin (WSP) in fruits. H2S‐treatment also inhibited the activities of polysaccharide degrading enzymes such as polygalacturonase (PG), pectin methylesterase (PME), pectin lyase (PL), cellulase (CL), and β‐galactosidase (β‐Gal). Transmission electron microscopy analysis suggested that H2S protected cell walls from structural breakdown. These results indicated that H2S is effective in delaying banana softening through regulating cell wall polysaccharides metabolism.
