BGS 610, Proanthocyanidin-free 30, ant30
Stock number: BGS 610
Locus name: Proanthocyanidin-free 30
Locus symbol: ant30
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (2, 3).
Location is unknown.
Description:
No anthocyanin pigmentation is observed in any vegetative plant parts. The leaves of the mutant plants show drastically reduced amounts of flavonoids, an increased UV-B sensitivity, and the chalcone-glucoside isosalipurposide is accumulated. The mutant plants are extremely sensitive to powdery mildew. The ant30 gene most likely codes for the chalcone isomerase enzyme, which catalyzes the conversion of chalcones into flavanones (3).
