Identification and Expression Analysis of DFR Gene Family in Brassica napus L.

Abstract: Dihydroflavonol 4-reductase (DFR) is a key enzyme in the flavonoid biosynthetic pathway and is essential for the formation of plants’ color. In this study, 26 BnDFR genes were identified using 6 Arabidopsis DFR genes as reference. The physicochemical properties, subcellular localization, and conserved structure of BnDFR proteins were analyzed; the evolutionary relationship, collinearity analysis, and expression characteristics of BnDFR genes were studied; and the correlation between the expression level of BnD… Show more

“…This indicates that the localization of the DFR gene is species-specific, and its localization differed from species to species; however, its role in scavenging ROS could remain same across species. In Brassica napus, a total of 26 BnDFR genes were localized in chloroplasts, cytoplasm, nuclei, and mitochondria [51], which is in accordance with our study. Interestingly, in our transcriptome analysis, genes (such as DFR, LAR, AT1, MAT, CHS2, CYP73A12, CHS3, BAHD1, and FLS) in the biosynthesis of secondary metabolite pathways were identified to be upregulated after 20 d exposure to different Mg levels (Figure 13), suggesting spontaneous activation of precursors involved in the biosynthesis of various antioxidants and flavonoids, which assist in counteracting the detrimental effects of Mg stresses.…”
