BGN  47:89 Export to PDF
Stock number: BGS 172
Locus name: Short awn 5
Locus symbol: lks5

Previous nomenclature and gene symbolization:

Short awn 5 = lk5 (7).
Breviaristatum-2 = ari-2 (5, 6).
Breviaristatum-c = ari-c.2 (6, 13, 14).

Inheritance:

Monofactorial recessive (6, 7).
Located in chromosome 4HL (15); lks5.f is about 6.9 cM distal from the Kap1 (Hooded lemma 1) locus (7, 9); lks5.f is near AFLP marker E4143-5 in subgroup 38 of the Proctor/Nudinka map (10); lks5.f is associated with SNP markers 1_0262 to 2_0072 (positions 76.26 to 95.92 cM) in 4H bin 06 of the Bowman backcross-derived line BW493 (2); ari-c.2 is associated with SNP markers 2_0289 to 2_1322 (positions 69.62 to 112.64 cM) in 4H bins 05 to 08 of the Bowman backcross-derived line BW040 (2), in 4H bin 06; lks5.p was isolated in genetic stocks BW474 and BW475 from the lel1 (leafy lemma 1) stock, G7118;, lks5.p is associated with SNP markers 2_1122 to 1_1019 (positions 47.80 to 183.54) in 4H bins 05 to 13 of the Bowman backcross-derived line BW474 (2); lks5.p is associated with SNP markers 2_0422 to 2_0072 (positions 38.41 to 95.92 cM) in 4H bins 04 to 06 of the Bowman backcross-derived line BW475 (2); in 4H bin 06.

Description:

Awns on both central and lateral spikelets are reduced to 1/4 or less of normal length in six-rowed cultivars (7). Only the central spikelets exhibit reduced awn length in two-rowed cultivars (3, 6). The rachilla is often modified, and in extreme cases the rachilla may develop as a malformed additional floret (7). Awns are thin and brittle 6). Plants of the Bowman backcross-derived line for lks5.f, BW493, had awns that extended 3 to 4 cm beyond the tip of the spike, while those of Bowman were 12 to 13 cm beyond the tip. Kernels of BW493 were slightly shorter, narrower (3.4 vs. 3.9 mm), and lighter (4.6 vs. 5.5 mg). BW493 plants were slightly taller than Bowman, and grain yields were slightly reduced (4). Presence of the mutant allele lks5.p is needed for expression of the leafy lemma 1 (lel1.a) gene (4, 10).

Origin of mutant:

A spontaneous mutant in an unknown cultivar (7).
