Summary: This study reveals the formation and mechanisms of (E)-2-hexenal during tea processing, and identifies the role of CsHI in this process. Additionally, it shows that abiotic stresses can regulate the proportions of (Z)-3-hexenal and (E)-2-hexenal in torn tea leaves by modulating CsHI expression levels. The findings of this study are important for the development of tea flavor and plant defense against abiotic stresses.

Summary: In this study, it was found that (E)-2-hexenal fumigation inhibits the growth of Botrytis cinerea. The research shows that (E)-2-hexenal fumigation reduces lesion diameter on strawberry and increases ROS and mitochondria membrane potential in B. cinerea. Furthermore, the study reveals the Michael addition reaction between (E)-2-hexenal and glutathione, as well as the concentration- and time-dependent effect of (E)-2-hexenal on glutathione and glutathione disulfide in B. cinerea.

Summary: This study investigated the effects of (E)-2-hexenal on Botrytis cinerea, a necrotrophic plant pathogen causing gray mold disease in tomatoes. The results showed that (E)-2-hexenal inhibited mycelial growth, causing distortion and loss of cytoplasm content in B. cinerea. Transcriptome sequencing revealed differential gene expression in response to (E)-2-hexenal, particularly affecting cell wall, cell membrane, and energy metabolism pathways. The study also found that (E)-2-hexenal influenced the biosynthesis and content of ergosterol, a vital component in B. cinerea. These findings contribute to understanding (E)-2-hexenal inhibition mechanisms and provide valuable information for postharvest shelf life extension and preservation of fruits and vegetables.

Summary: In this study, the molecular mechanisms regulating defense responses in tomato leaves exposed to (E)-2-hexenal were elucidated using LC-MS and RNA sequencing techniques. The results showed that many genes and metabolites were regulated, and mitogen-activated protein kinase (MPK), pathogenesis-related protein (PR), and endochitinase (CHIB) were primarily responsible for plant defense response adaptation. These findings help us understand the defense response of plants to (E)-2-hexenal and improve the resistance of horticultural plants.

Summary: This study investigated the effects of adding (E)-2-hexenal and 2,3-butanediol into the medium on bioactive metabolites in Astragalus membranaceus var. mongholicus adventitious root cultures. The results showed that the combination of 2,3-butanediol and (E)-2-hexenal promoted the accumulation of astragaloside IV, while their individual application delayed it. The production of CG and ononin was not significantly affected, but their accumulation patterns were changed. This finding provides important insights into the production of bioactive products in herbal plants.

Summary: The study found that (E)-2-hexenal can enhance the assimilation of sulfate byBotrytis cinerea at low concentrations, leading to increased infection severity in tomato and strawberry fruits. The results suggest that sulfate assimilation is a key factor affecting B. cinerea infection, and it is proportional to the sulfur content in the fruits.

Summary: In this study, the global mechanism underlying (E)-2-hexenal-mediated regulation of biotic stress tolerance in tomato was investigated using transcriptomic and proteomic analyses. The results showed that (E)-2-hexenal treatment reduced susceptibility to B. cinerea and increased antioxidant enzyme activities. The analysis also revealed the modulation of genes involved in various metabolic pathways and the activities of defense response proteins.

Summary: The isothermal vapor + liquid equilibria of carbon dioxide + (E)-2-hexenal were investigated using a visual equilibrium cell with an analytic methodology. The thermodynamic consistency of the experimental data was verified, and uncertainties of the molar fractions of the vapor and liquid phases were estimated. Two equations of state were selected to model the vapor + liquid equilibria.

Summary: Hexanal and (E)-2-hexenal in soymilk are mainly formed during the soaking and grinding of soybeans. The study found that different phosphatidylcholine molecules were preferentially acted upon by lipoxygenases (LOXs), with 1-palmitoyl-2-linoleoyl-sn-3-phosphatidylcholine and 1-stearoyl-2-linoleoyl-sn-3-phosphatidylcholine making predominant contributions to hexanal/(E)-2-hexenal formation. Phospholipase A(2) (PLA(2)) was identified as one of the key enzymes involved in this process.

Summary: In this study, a nickel-based catalyst was synthesized and its performance was tested in a batch reactor. The effect of reaction parameters on the catalytic activity and selectivity was evaluated. The results showed that the catalyst with 53% nickel loading exhibited the highest catalytic activity, with 100% EPA conversion and 81% EH selectivity. Copper was found to be the most effective catalyst promoter.

The Schiff-base ligands are in a zwitterionic form and coordinate through the phenolic oxygen only. The complex exhibits a triclinic crystal structure and shows potential as a light emitting material in the visible region.
