BGN 29: BGS 606, Proanthocyanidin-free 26, ant26

BGS 606, Proanthocyanidin-free 26, ant26

Stock number: BGS 606
Locus name: Proanthocyanidin-free 26
Locus symbol: ant26

Previous nomenclature and symbolization:

None.
Inheritance:
Monofactorial recessive (2, 4, 5).
Location is unknown.
Description:
Mutant plants develop a wildtype amount of anthocyanin pigments in the vegetative parts. Developing grains synthesize catechin and trace amounts of proanthocyanidins, whereas mature grains are classified as proanthocyanidin-free (3). The ant26 gene might control the putative flavanol-condensing enzyme, which catalyzes the condensation of leucoanthocyanidins and catechins to dimeric proanthocyanidins (3, 6).
Origin of mutant:
A sodium azide induced mutant in Grit (PI 548764, NGB 13685) (1).
Mutational events:
ant26.483, 26.485, 26.486, 26.487 in Grit (2); ant26.2002, 26.2004 in Grit (4); ant26.2008, 26.2009 in Grit (5).
Mutant used for description and seed stock:
ant26.483 in Grit (NGB 13707, GSHO 1639); ant26.485 in Grit (NGB 13708).
