Figure 4From: Analysis of T-DNA alleles of flavonoid biosynthesis genes in Arabidopsis ecotype ColumbiaUPLC analysis of flavonol aglycone profiles in T-DNA insertion lines. A) UPLC traces of hydrolyzed extracts prepared from 5-day-old seedlings, with arrows indicating the retention times of the flavonols, quercetin (Q) and kaempferol (K). B) Comparison of kaempferol and quercetin levels determined from integrated peak areas.Back to article page
