additional information gene expression of FtLAR during sprout development under dark and light conditions in cvs. T8 and T10, determination of catechin and epicatechin contents in sprouts, the expression pattern of anthocyanidin reductase (ANR) and leucoanthocyanidin reductase (LAR) do not match the accumulation pattern of proanthocyanidins in different organs of the two cultivars Hokkai T8 and Hokkai T10. FtLAR does not show large variations in its expression patterns among all the organs in cultivars Hokkai T8 and T10. Epicatechin content is higher than the catechin content in both T8 and T10. In T10, catechin is found mostly in the flowers and roots, whereas in T8, higher amounts are found in leaves and seeds at stage 1. Catechin content in T10 is highest in roots. Hokkai T10 wild roots in the soil and hairy roots are red in color. The catechin content is correlated with color pigment Fagopyrum tataricum

General Information

General Information Comment Organism
metabolism the enzyme is important in biosynthesis of proanthocyanidins (PAs) such as catechin and epicatechin, the proanthocyanidin pathway exists as ametabolic channel associated with cellular membranes Fagopyrum tataricum
additional information FtLAR had specific amino acid motifs of ICCN and THD Fagopyrum tataricum
physiological function leucoanthocyanidin reductase (LAR), together with anthocyanidin reductase (ANR, EC 1.3.1.77), plays an important role in the monomeric units biosynthesis of proanthocyanidins (PAs) such as catechin and epicatechin in several plants. ANR and LAR levels in tartary buckwheat might be regulated by different mechanisms for catechin and epicatechin biosynthesis under light and dark conditions. The catechin content is correlated with color pigment in roots Fagopyrum tataricum
