BGS 601 Proanthocyanidin-free 19, ant19

Stock number: BGS 601
Locus name: Proanthocyanidin-free 19
Locus symbol: ant19

Previous nomenclature and symbolization:

None.
Inheritance:
Monofactorial resessive (2).
Location is unknown.
Description:
The mutant plants synthesize a wildtype 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).
Origin of mutant:
A sodium azide induced mutant in Alf (NGB 13682) (1).
Mutational events:
ant19.109 in Alf (2).
Mutant used for description and seed stock:
ant19.109 in Alf (NGB 13703, GSHO 1631).
