BGS 606, Proanthocyanidin-free 26, ant26
Stock number: BGS 606
Locus name: Proanthocyanidin-free 26
Locus symbol: ant26
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (2, 4, 5).
Location is unknown.
Description:
Mutant plants develop a wild type 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).
