Abstract
Introduction Hu sheep, known for its high quality and productivity, lack fundamental scientific research in China. Methods This study focused on the effects of 24 h postmortem aging on the meat physiological and transcriptomic alteration in Hu sheep. Results The results showed that the 24 h aging process exerts a substantial influence on the mutton color, texture, and water content as compared to untreated group. Transcriptomic analysis identified 1,668 differentially expressed genes. Functional enrichment analysis highlighted the importance of glycolysis metabolism, protein processing in endoplasmic reticulum, and the FcγR-mediated phagocytosis pathway in mediating meat quality modification following postmortem aging. Furthermore, protein-protein interaction analysis uncovered complex regulatory networks involving glycolysis, the MAPK signaling pathway, protein metabolism, and the immune response. Discussion Collectively, these findings offer valuable insights into the molecular mechanisms underlying meat quality changes during postmortem aging in Hu sheep, emphasizing the potential for improving quality control strategies in mutton production.

Abstract
Avicennia marina (Forsk.) Vierh. is a typical mangrove plant. Its epidermis contains salt glands, which can secrete excess salts onto the leaf surfaces, improving the salt tolerance of the plants. However, knowledge on the epidermis-specific transcriptional responses of A. marina to salinity treatment is lacking. Thus, physiological and transcriptomic techniques were applied to unravel the salt tolerance mechanism of A. marina. Our results showed that 400 mM NaCl significantly reduced the plant height, leaf area, leaf biomass and photosynthesis of A. marina. In addition, 1565 differentially expressed genes were identified, of which 634 and 931 were up- and down-regulated. Based on Kyoto Encyclopedia of Genes and Genomes metabolic pathway enrichment analysis, we demonstrated that decreased gene expression, especially that of OEE1, PQL2, FDX3, ATPC, GAPDH, PRK, FBP and RPE, could explain the inhibited photosynthesis caused by salt treatment. Furthermore, the ability of A. marina to cope with 400 mM NaCl treatment was dependent on appropriate hormone signalling and potential sulfur-containing metabolites, such as hydrogen sulfide and cysteine biosynthesis. Overall, the present study provides a theoretical basis for the adaption of A. marina to saline habitats and a reference for studying the salt tolerance mechanism of other mangrove plants.
