gene P or Sb06g029550, genetic structure, quantitative RT-PCR enzyme expression analysis

Sorghum bicolor

additional information

expression of both flavone synthase II (FNSII) and flavonoid 3'-hydroxylase (F3'H) leads to the synthesis of apigenin and luteolin in cultivar #7, and expression of both flavanone 4-reductase and F3'H leads to the synthesis of 3-deoxyanthocyanidins in cultivar Nakei-MS3B

Sorghum bicolor

the enzyme is highly induced by cutting stress

up

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

Sorghum bicolor

physiological function

the enzyme is responsible for the synthesis of 3-deoxyanthocyanidins. The variation of purple-red-orange is explained by the balance of two 3-deoxyanthocyanidins, uteolinidin and apigeninidin. The balance is controlled by the expression level of flavonoid 3'-hydroxylase (F3'H), which encodes a protein that hydroxylates the 3' position of the B-ring of naringenin to produce a precursor of luteolinidin
