- Abstract
Anthocyanins and selenium (Se) have antioxidant properties and are crucial to human health. Previous works have well studied the role of exogenous Se fertilization in grain quality and anthocyanin formation in colored crops, whereas few reports on naturally Se-enriched colored grains exist. In this study, the quality, anthocyanin accumulation, and metabolism of natural Se-enriched purple waxy corn and common purple waxy corn were compared during kernel development. Natural Se-enriched purple waxy corn had higher concentrations of total Se, anthocyanins, flavones, starch (branched- and straight-chain), and sugar than common purple waxy corn, and the optimum eating date was 28 days after pollination. Genes related to anthocyanin biosynthesis were significantly upregulated in natural Se-enriched purple waxy corn, resulting in enriched anthocyanin metabolites (6-O-malonyl-beta-D-glu and 3-O-glu in Cy, Pn, and Pg). Most importantly, genetic alterations were observed which several genes and transcription factors were downregulated some branch pathways of lignin synthesis and accelerated anthocyanin synthesis. Our results profiled anthocyanin metabolism in naturally Se-enriched purple waxy corn to promote harvesting.
