BGS 601, Proanthocyanidin-free 19, ant19
Stock number: BGS 601
Locus name: Proanthocyanidin-free 19
Locus symbol: ant19
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (2).
Location is unknown.
Description:
The mutant plants synthesize a wild type amount of anthocyanins in their vegetative parts, but the testa layers of the grains lack catechins and proanthocyanidins (2). The ant19 gene is probably the structural gene coding for leucoanthocyanidin reductase, the enzyme catalyzing the conversion of leucoanthocyanidins into catechins (3, 4).
