Summary: In this study, we investigated the effect and mechanism of an ATP-binding cassette transporter, SlABCG23, on the chilling resistance of tomato fruit during storage. We found that mutation of SlABCG23 resulted in severe chilling injury, decreased jasmonic acid contents, and increased expression levels of the JA signaling inhibitor, SlJAZ6. This mutation also led to a decrease in fruit pericarp thickness, lower expression levels of cold response genes, and reduced antioxidant enzyme activities.

Summary: In this study, the researchers found that the tomato SBP-box protein SlCNR plays a role in regulating fruit wax accumulation and postharvest water loss. The overexpression of SlCNR led to decreased wax accumulation and increased water loss, while the knockout of SlCNR resulted in increased wax accumulation and decreased water loss. RNA-seq analysis revealed that SlCNR directly repressed the expression of wax biosynthetic genes, such as SlCER1-2 and SlCER6. These findings provide new insights into the genetic regulatory mechanisms of fruit wax accumulation in tomatoes.

Summary: This study evaluated a large set of blueberry cultivars to understand the relationship between mechanical texture and appearance characteristics at harvest and after storage, and tested multiple statistical models to predict shelf-life. The results showed that fruit characteristics measured at harvest or two weeks post-harvest can predict weight loss, texture change, and fruit wrinkling. These findings provide empirical data that blueberry breeders can use to select cultivars with extended shelf-life.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.

Summary: Invasive tephritid fruit flies pose a significant threat to commercial fruit and vegetable production. Early detection is crucial, and male lures are an important component of trapping networks. This review aims to summarize data on the change in attractiveness of male lures during aging in the field, highlighting studies that relate trap captures to changes in residual content and release rate.

Summary: After harvest, pumpkin fruit undergoes strong respiration and metabolic activities, leading to quality deterioration and shortened storage period. This study investigated the mechanisms of quality change in different pumpkin varieties during storage. Changes in cell wall components, enzyme activities, and fruit texture were monitored. The results showed that pumpkin fruit texture changed during storage, and there were variations in cell wall components and enzymatic activities among different varieties.

Summary: Globally, fresh produce plays a crucial role in nutrition, health, food security, and economic growth. However, low and middle-income countries suffer the most from significant postharvest losses of fruit and vegetables. Extensive research and innovation have been conducted in the past three decades to address this issue, with a shift towards alternative control strategies and the use of plant-based compounds, edible coatings, and biofilms. China and the USA are the leading players in global fresh produce postharvest research, while South Africa and Egypt are key players in Africa. Despite the progress made, there is still a need to strengthen research investment and collaboration, particularly among low and middle-income countries.

Summary: This study aimed to compare the discrimination ability and detection limit of visible and short-wave near-infrared hyperspectral imaging features and spectral information on early implicit bruised pears. Physical characteristics were more sensitive than chemical parameters for bruised pears during postharvest storage. The changes in spectral variations at specific wavelengths could explain the bruising changes in pears. Discrimination models based on selected spectral variables could effectively identify bruised pear areas, and the combination of imaging features and spectral variables achieved higher discrimination rates.

Summary: This research aimed to investigate the potential action mechanism of gamma-aminobutyric acid (GABA) in controlling Botrytis cinerea (B. cinerea) in tomato fruit. The findings showed that GABA treatment effectively reduced the disease incidence and lesion diameter of tomato fruit caused by B. cinerea. GABA triggered defense responses and up-regulated the expression of pathogenesis-related genes, while also inhibiting the expression of ethylene synthesis genes.

Summary: In this study, hollow and solid lignin nanoparticles were synthesized through self-assembly and their application in PVA nanocomposite films was investigated. The results showed that the presence of hollow lignin nanoparticles in the films resulted in a room-like network structure, while the solid lignin nanoparticles induced different structural changes. The inclusion of LNPs improved the mechanical properties of the films, and both types of LNPs exhibited good hydrophobicity.
