Comparative Metabolic Analysis of Different Rice Varieties Associated with Seed Storability.
Metabolites
January 2025
Rice Research Institute, Fujian Academy of Agricultural Sciences, Fuzhou 350019, China.
Unlabelled: Seed storability is a crucial agronomic trait and indispensable for the safe storage of rice seeds and grains. Nevertheless, the metabolite mechanisms governing rice seed storability under natural conditions are still poorly understood.
Methods: Therefore, the seed storage tolerance of global rice core germplasms stored for two years under natural aging conditions were identified, and two extreme groups with different seed storabilities from the rice group were analyzed using the UPLC-MS/MS metabolomic strategy.
The road of lipid migration in flaxseed (Linum usitatissimum L.) during germination.

Research Center of Grain and Oil Functionalized Processing in Universities of Shaanxi Province, College of Food Science and Engineering, Northwest A&F University, 22 Xinong Road, Yangling 712100, Shaanxi, PR China. Electronic address:
Lipids are essential sources of carbon and energy during flaxseed germination; however, the dynamic changes in key lipid metabolites, pathways, and their locations remain unclear. This study revealed that oil bodies migrated from well-distributed locations to the cell wall between 0-2 d, with cell contours gradually blurring during 2-3 d, initiating the germination process. Subsequently, the order of oil body migration was leaf > stem > root during 4-7 d.

Institute of Food Science and Technology, Chinese Academy of Agricultural Sciences, Beijing 100193, China. Electronic address:
To explore the effect of oleic acid, linoleic acid, and linolenic acid on "glucose-glutathione" Maillard reaction initial stage and meaty flavor compounds formation pathways, glutathione-Amadori compound was synthesized, and identified by Q/TOF and NMR. Depending on the concentration of glutathione and glutathione-Amadori compound quantified by UPLC-MS/MS, the unsaturated C18 fat acids inhibited glutathione Amadori compound formation or accelerated degradation, and oleic acid inhibited most markedly. The results showed that 65 volatile compounds were detected by GC-MS-O in four model systems.

January 2025
State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangdong Provincial Key Laboratory of Ophthalmology and Visual Science, Guangdong Provincial Clinical Research Center for Ocular Diseases, Guangzhou, 510060, China.
Background: Herpes simplex keratitis (HSK) is a recurrent inflammatory disease of cornea primarily initiated by type I herpes simplex virus infection of corneal epithelium. However, early diagnosis of HSK remains challenging due to the lack of specific biomarkers. This study aims to identify biomarkers for HSK through tear metabolomics analysis between HSK and healthy individuals.
