Stock number: BGS 598
Locus name: Proanthocyanidin-free 13
Locus symbol: ant13

Previous nomenclature and symbolization:

None.

Monofactorial recessive (4, 5).
Located in chromosome 6HL, near the centromere and the sex1 (shrunken endosperm xenia1) locus (1).

Under normal growing conditions no anthocyanin pigmentation is observed in any of the vegetative plant parts (10). Under stress conditions anthocyanin pigmentation can occur in the mutant plants, but it is never as strong as in the wildtype. The testa layers of the grains of the ant13 mutants are totally lacking proanthocyanidins and precursors of proanthocyanidins. The ant13 locus is coding for a transcription factor involved in the expression of the structural genes in the flavonoid pathway (7, 11). Almost all mutant alleles are induced with sodium azide (3).

An ethyl methanesulfonate induced mutant in Foma (CIho 11333) (2).
