Project description:In order to investigate the physiological and biochemical characteristics and molecular mechanisms during the leaf colour change of Acer rubrum L, this study used Acer rubrum L. 'Autumn Blaze' cuttings as material and analysed the transcriptome and miRNAs of Acer rubrum L leaves under different light and temperature treatments. The transcriptome and miRNAs of Acer rubrum L leaves were analysed under different light and temperature treatments, and miRNA-mRNA association analysis was performed for the differentially expressed mRNAs and miRNAs.
Project description:Equine atypical myopathy (AM) is a severe environmental intoxication linked to the ingestion of protoxins contained in seeds and seedlings of the sycamore maple (Acer pseudoplatanus) in Europe. The toxic metabolites cause a frequently fatal rhabdomyolysis syndrome in grazing horses. Since toxic metabolites can also be present in co-grazing horses, it is still unclear as to why, in a similar environmental context, some horses show signs of AM whereas others remain clinically healthy. Label-free proteomics analyses on the serum of 26 diseased AM, 23 co-grazers and 11 control horses were performed to provide insights into biological processes and pathways. A total of 43 and 44 differentially expressed proteins between “AM vs co-grazing horses” and “AM vs control horses” were found. Disease-linked changes in the proteome of different groups were found to correlate with detected amounts of toxins and principal component analysis was performed to identify the 29 proteins with the greatest impact on the proteomic differences between groups. Among the pathway-specific changes the glycolysis/gluconeogenesis pathway, the coagulation/complement cascade, and the biosynthesis of amino acid were affected. Sycamore maple poisoning results in a combination of inflammation, oxidative stress, and high energy demand, which is trying to be met by enhanced glycolysis.
Project description:To reveal the molecular mechanism of leaf color changes in Acer pictum subsp. mono, this study was conducted on bud-transformed branches, analyzing the transcriptome and small RNAs of Acer pictum subsp. mono leaves and performing miRNA-mRNA association analysis on differentially expressed mRNAs and miRNAs.
