BGS 89, Breviaristatum-g, ari-g

BGN  47:66
Stock number: BGS 89
Locus name: Breviaristatum-g
Locus symbol: ari-g

Previous nomenclature and gene symbolization:

Breviaristatum-18 = ari-18 (4, 5).
Short awn 10 = lk10 (7).


Monofactorial recessive (5).
Located in chromosome 2H (1, 3); ari-g.24 is associated based on linkage drag with the Gth1 (Toothed lemma 1) locus (1), but the association may be caused by poor expression of the Gth1.a allele in the Bowman backcross-derived line (2, 3); ari-g.24 is associated with SNP markers 1-0796 to 2_0528 (positions 95.53 to 118.78 cM) in 2H bins 07 to 08 of a heterozygous plant from the Bowman backcross-derived line BW045 (1).


Plants with the ari-g mutation are semidwarf and very weak. Under greenhouse conditions, plants are 1/4 to 1/3 normal and stiff, spikes are short and small, and seed set is low. Leaf blades are very narrow often involuted and are white and green striped (5, 6). When grown in the field at Fargo, North Dakota, USA, plant development is very slow, the upper portion of the sheath is white as new leaf blades emerge, and spikes are seldom produced. Thus, the Bowman backcross-derived line for ari-g.24, BW045, is maintained as a segregating stock (2).

Origin of mutant:
