As a filamentous and spoilage fungus, spp. can not only infect processing tomatoes, but also produce a variety of mycotoxins which harm the health of human beings. To explore the production of toxins in processing tomatoes during growth and storage, four main toxins and four conjugated toxins were detected by ultrahigh-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) and ultra-performance liquid chromatography-ion mobility quadrupole time-of-flight mass spectrometry (UPLC-IMS QToF MS) in processing tomatoes on different days after being inoculated with . The results show that the content of toxins in an in vivo assay is higher than that under field conditions. Tenuazonic acid (TeA) is the predominant toxin detected in the field (205.86~41,389.19 μg/kg) and in vivo (7.64~526,986.37 μg/kg) experiments, and the second-most abundant toxin is alternariol (AOH). In addition, a small quantity of conjugated toxins, AOH-9-glucoside (AOH-9-Glc) and alternariol monomethyl ether-3-glucoside (AME-3-Glc), were screened in the in vivo experiment. This is the first time the potential of toxins produced in tomatoes during the harvest period has been studied in order to provide data for the prevention and control of toxins.

Polymeric high internal phase emulsions decorated with covalent organic frameworks (polyHIPEs-COFs) were synthesized and used as the sorbent for cyantraniliprole and chlorantraniliprole. Pickering high internal phase emulsions stabilized by covalent organic frameworks solid particles and liquid surfactants (Span80 and polyvinylpyrrolidone) endow the composites with open-cell structures and superwettability. The amphiphilicity and open-cell structures enable rapid adsorption and desorption for cyantraniliprole and chlorantraniliprole, and the solid-phase extraction process can be completed in 5 min.

Protein phosphatases (PPs) are a class of enzymes that play a critical role in cellular regulation by catalyzing the removal of phosphate groups from proteins. This dephosphorylation process is essential for controlling and modulating various cellular functions, including signal transduction, cell cycle progression, metabolic regulation, and stress responses. This study focuses on the comprehensive genomic identification, evolutionary analysis, and transcript profiling of the PP2C gene family within Solanum lycopersicum, an economically significant crop with substantial agricultural and nutritional importance.

Composite polymers are promising solution to structural setbacks of starch and alginate-based films due to their hydrophilic attributes. Hence, this study aimed to investigate young coconut jelly powder (CJP), an under-utilized by-waste, as a filler using the casting method to develop a novel biocomposite from increments of CJP (1-3 %) to a blended resin of arrowroot starch, sodium alginate, and glycerol. Moreover, the films were characterized by physicomechanical (visual aspect, thickness, color, moisture content, tensile strength, and elongation at break); surface microstructure; water barrier (water vapor permeability, water solubility, and water activities); thermal, crystallinity, and functional group properties; soil, river water, and seawater biodegradability; and coating application in cherry tomato.

Background: Fresh vegetables are commodities that have a high tendency to deteriorate after harvest, causing significant losses in economic and environmental costs associated with plant food loss. Therefore, this study was carried out to evaluate the effects of both un-irradiated (UISA) and irradiated sodium alginate (ISA) as an edible coating for preserving cherry tomato fruits under storage conditions. The FTIR, XRD, TGA, SEM, and TEM were used to characterize the UISA and ISA (25, 50, 75, and 100 kGy), which demonstrated that the alginate polymer was degraded and low molecular-weight polysaccharides were formed as a result of irradiation, particularly with the 100 kGy dose level.

Cellular responses to biotic stress frequently involve signaling pathways that are conserved across eukaryotes. These pathways include the cytoskeleton, a proteinaceous network that senses external cues at the cell surface and signals to interior cellular components. During biotic stress, dynamic cytoskeletal rearrangements serve as a platform from which early immune-associated processes are organized and activated.
