BGS 746, Anthocyanin-deficient 23, ant23

BGN  48:176
Stock number: BGS 746
Locus name: Anthocyanin-deficient 23
Locus symbol: ant23

Previous nomenclature and gene symbolization:

Exrubrum = rub-a (4).
Anthocyanin-deficient 3 = ant-3 (3, 6).


Monofactorial recessive (5, 6).
Located in chromosomes 2HL or 5HL (1); ant23.3 is associated with SNP markers 1_1346 to 2_1459 (163.20 to 202.70 cM) in chromosome 2HL in bins 11 to 13 and 2_0127 to 2_0731 (189.08 to 223.57 cM) in chromosome 5HL bins 10 to 12 of the Bowman backcross-derived line BW023 (1).


Just prior to physiological maturity, the ant23.3 mutation showed no anthocyanin pigmentation of culms and auricles and reduced anthocyanin pigmentation of awns and lemmas (5). The Bowman backcross-derived line for ant23.3 (BW023) was selected in F2 progenies grown in greenhouses based on the absence of basal stem pigmentation in seedlings before heading (2). The retention of SNP markers from Bonus in BW023 in the long arms of chromosomes 2H and 5H suggests that these chromosomal regions are associated with the lack of basal stem pigmentation (1, 2). SNP markers were retained in same two chromosomal regions in BW025, the Bowman backcross-derived line for ant5.9, anthocyanin-deficient 5 (1, 2).
