Genome-Wide Association Study of Phenolic Content and Antioxidant Properties in Eggplant Germplasm

The phenolic compounds in eggplant offer potential natural antioxidants for improved health. A large number of samples were examined order to find germplasm with a high health promotion. genome-wide association study (GWAS) was conducted identify single nucleotide polymorphisms (SNPs) associated variations total content (TPC) and antioxidant activity eggplants, including ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) scavenging ferric reducing power (FRAP). TPC values varied from 14.19 842.90 mg gallic acid equivalent (GAE)/100 g dry weight fruit powder. showed strong positive correlation both FRAP (r = 0.89 *** 0.77 ***, respectively). GWAS identified 20 SNPs that significantly out 29,183 SNPs. Out the significant SNPs, 11 associations TPC, 4 activity, 5 FRAP. Among one SNP found on each Chromosomes 3, 4, 7, 12. In contrast, Chromosome comprised two TPC. Furthermore, gene encoding IRX12 laccase-4 10 contain five Four linked 1 (1 SNP), (2 SNPs), SNP) be related activity. will further as markers selecting desirable varieties exploring links between candidate genes, content, findings this could assist development eggplants advantages through targeted breeding.
