Common Names: carnation
Study evaluated antioxidant and antitumor properties of carnation plant extracts using metabolomics. Important for potential medicinal and ornamental value.
DNA methylation in the promoter region of genes increases during flower senescence in carnation. DcROS1 gene is involved, and its overexpression delays senescence. Amino acid biosynthesis genes affected by DNA methylation influence flower senescence. DcROS1 plays a role in DNA methylation and amino acid biosynthesis during flower senescence.
Scientists assembled the genome of carnation, a popular cut flower, at the chromosome level. They identified structural variations and transposable elements, and estimated the species differentiation time. The genome facilitates molecular biology and evolutionary studies.
Purple carnation flowers have been found to have the highest antioxidant and anticancer activities compared to other colors. Through a metabolomics analysis, 932 metabolites were identified and categorized, with several flavonoids, organic acids, phenolic acids, and nucleotides found as specific differential metabolites in purple flowers. Further analysis revealed that 6-hydroxykaempferol-3,6--diglucoside, 6-hydroxykaempferol-7--glucoside, quercetin-3--sophoroside, and 2'-deoxyguanosine were the major constituents responsible for the antioxidant and anticancer activities. Additionally, 2'-deoxyguanosine showed effective antiproliferative activity against certain cancer cells, and its combination with other compounds further enhanced its antitumor activity. These findings expand our knowledge of carnation's phytochemical composition and offer potential for improving the quality of carnation flowers.
