BGS 596, Anthocyanin-deficient 5, ant5
Stock number: BGS 596
Locus name: Anthocyanin-deficient 5
Locus symbol: ant5
Previous nomenclature and gene symbolization:
Green stem = rs2 (2).
Exrubrum = rub-a (4).
Exrubrum = rub-a (4).
Inheritance:
Monofactorial recessive (5, 6).
Located in chromosome 7HL (2); ant5.9 is possibly allelic to the blx5.e (non-blue aleurone 5) gene (2, 6); the Bowman backcross-derived line for ant5.9 (BW025) retained donor parent SNP markers 1_1346 to 1_0429 (163.20 to 183.40 cM) in chromosome 2HL in bin 11 and 2_0298 to 1_0236 (203.85 to 276.77 cM) in chromosome 5HL bins 11 to 14 (1).

Description:
Just prior to maturity, the ant5.9 mutation showed no anthocyanin pigmentation of culms, auricles, and awns and reduced anthocyanin pigmentation of lemmas (5).
The mutant plants do not synthesize anthocyanins in their vegetative parts under normal growing conditions (6, 7). The stem does not develop a purple pigmentation as plants approaches maturity (2). The Bowman backcross-derived line for ant5.9 (BW025) was selected in F2 progenies based on the absence of basal stem pigmentation in greenhouse grown seedlings before heading (3). Plants of the Bowman backcross-derived line for ant5.9 (BW025) were similar to those of Bowman except for anthocyanin pigmentation (3).
