Ginger， rich in gingerols and shogaols， exhibits multiple biological properties. However， the mechanisms underlying its thermotolerance remain unclear. The study employed network pharmacology and experimental validation in Caenorhabditis elegans to investigate how gingerol-related compounds within ginger extract (GE) mitigated damage caused by heat stress (HS). A total of 18 types of gingerol analogues were identified in GE， among which 6-， 8-， and 10-gingerol， as well as 6-， 8-， and 10-shogaol were quantified. Collectively， these six compounds accounted for 54.4% of the total composition. Supplementation with 15 μg/mL GE significantly extended heat-stress lifespan by 20.30%， while the combination of the six major gingerols and shogaols at the same concentration prolonged lifespan by 18.93%. Additionally， pretreatment with GE and the combination alleviated HS-induced oxidative damage by eliminating reactive oxygen species (ROS) and upregulating antioxidant enzymes. Network pharmacology analysis suggested that the MAPK pathway may play a crucial role in thermotolerance. Experimental findings confirmed that ginger attenuated oxidative damage through the activation of SKN-1/Nrf2 and DAF-16/FOXO via the MAPK pathway. Moreover， GE stabilized mitochondrial membrane potential and restored ATP levels， thus preserving mitochondrial function during heat exposure. Further investigations using molecular docking and molecular dynamics simulations revealed that shogaols， with more stable binding affinities for KEAP1 protein， exhibited more potent effects than gingerols in prolonging lifespan and reducing ROS levels under HS conditions. In short， gingerol analogues from ginger conferred thermal resistance to nematodes by mitigating oxidative damage and mitochondrial dysfunction.

Grass carp fillets were susceptible to unpleasant fishiness during cold storage. To clarify the mechanism of fishy odor formation and achieve targeted regulation， volatile compounds， and lipid oxidation were investigated in grass carp fillets during cold storage （0-7d）. The lipid oxidation degree increased continually during cold storage， as evidenced by the change of AV， POV， TBARS， and HP. The activities of related enzymes (LOX， LPS， PLA[2]， and HPL) maintained a high level， reaching their maximums after 3-5 days. Free fatty acids exhibited a great downtrend， especially linoleic acid （18:2） and arachidonic acid （20:4）. Forty-five volatile compounds were identified by solvent-assisted flavor evaporation-gas chromatography-mass spectrometer， and the total contents of volatile compounds increased from 706.55 μg/kg （0d） to 1370.65 μg/kg （7d）. （Z）-4-heptenal，（E，E）-2，4-hexadienal， 1-penten-3-ol， nonanal， and （E）-2-heptenal were the key volatile compounds. The Pearson correlation showed a strong correlation between 47 differentially abundant lipids （variables important in projection > 1， P value 2） and volatile compounds. During cold storage， lyso-phosphatidylcholine （20:4） and lyso-phosphatidylcholine （18:2） were selected as the main precursors of volatile compounds’ formation in grass carp fillets.

Rice is the world's largest food crop, but it often encounters flowering asynchronization problems during hybrid rice seed production. In addition, the slow closure of female florets leads to seed mildew and affects the quality. The hormone abscisic acid(ABA) plays a crucial role in plant responses to abiotic stresses. Previous studies showed that exogenous ABA promotes floret closure, although the molecular mechanisms and effects of endogenous ABA on floret closure remain unknown. In this study, the effect of endogenous ABA on floret closure and the molecular mechanism by which ABA promotes floret closure through sugar transporters were investigated by changing the expression levels of OsNCED3 and OsPYL1 in rice. The results showed that overexpression(OE)-OsNCED3increased the endogenous ABA level of florets. Florets closed 5.91 min earlier and OsNCED3 gene knockout line delayed the closure of florets by 5.08 min compared with the wild type. In addition, OsPYL1 regulated the endogenous ABA content and changed the sensitivity to ABA such that the floret closure times for OE and CRISPR-Cas9(CR) were 9.84 min earlier and 12.78 min later, respectively, resulting in an increase in the split husk rate to 15.4%. The gene expression levels of some sugar transporters(STs) changed. The OsPYL1 and OsSWEET4proteins could interact on the cell membrane. These results indicate that ABA promotes the closure of rice florets and the enhanced sensitivity to ABA promotes this effect even more. The molecular mechanism is mainly related to downstream sugar transporters that respond to the ABA signaling pathway, especially OsSWEET4.
