BGS 603, Proanthocyanidin-free 21, ant21

Stock number: BGS 603
Locus name: Proanthocyanidin-free 21
Locus symbol: ant21

Previous nomenclature and symbolization:

None.
Inheritance:
Monofactorial recessive (3, 4).
Located in chromosome 6H, close to the centromere (1).
Description:
Under normal growing conditions no anthocyanins are observed in the vegetative parts of the mutant plants. The mutant grains lack proanthocyanidins and no precursors of proanthocyanidins are accumulated. The action of the gene ant21 is unknown, but it might be involved in the regulation of anthocyanin and proanthocyanidin biosynthesis (5, 6).
Origin of mutant:
A sodium azide induced mutant in Georgie (PI 447012, NGB 13683) (2).
Mutational events:
ant21.194 in Georgie (3); ant21.207 in Hege 876 (4); ant21.271 in Secobra 18193 (NGB 13684) (4); ant21.526 in Advance (CIho 15804) (4); ant21.1507 in Amagi-Nijo (3); ant21.1513 in Haruna-Nijo (3); ant21.1514 in Nirakei 61 (4); ant21.1516 in Nirakei 61 (3).
Mutant used for description and seed stock:
ant21.194 in Georgie (NGB 13704); ant21.1513 in Haruna-Nijo (GSHO 1634); ant21.1513 in Bowman (PI 483237)*4 (GHSO 1855).
