BGS 607, Proanthocyanidin-free 27, ant27

BGN  29:98
Stock number: BGS 607
Locus name: Proanthocyanidin-free 27
Locus symbol: ant27

Previous nomenclature and gene symbolization:



Monofactorial recessive (2, 4).
Location is unknown.


Mutant plants produce a wild type amount of anthocyanins in their vegetative parts. The testa layers of the mature grains lack catechins and proanthocyanidins (2). The action of the ant27 gene is unknown, but it might be involved in the condensation reaction of leucoanthocyanidin and catechin to yield proanthocyanidins or in the regulation of the proanthocyanidin specific branch of the flavonoid pathway (3, 5).
