LITERATURE
evolution
the enzyme belongs to the plant DFR superfamily, phylogenetic analysis
malfunction
Sorghums with a tan injury response have non-functional FNR alleles (p). The FNR gene of cultivar M36001 has an insertion in the coding region. Sorghums with a tan injury response have lower levels of flavan-4-ols (precursors of apigeninidin and luteolinidin-apiforol and luteoforol, respectively) than do sorghums with a purple or red injury response and are unable to synthesize 3-deoxyanthocyanidins
