BGN  43:64 Export to PDF
Stock number: BGS 57
Locus name: Elongated outer glume 1
Locus symbol: eog1

Previous nomenclature and gene symbolization:

Extended outer glumes = e (10).
Wide glumes = w (10).
Macrolepis = lep-e (lep-a) (7, 14, 15).
Long outer glume = log (16).
Elongated outer glume = e (3, 16).

Inheritance:

Monofactorial recessive (1, 2, 17).
Located in chromosome 2HL (6); eog1.a is about 30.5 cM proximal from the vrs1 (six-rowed spike 1) locus (3, 11); eog1.a is associated with SNP markers 2_0387 to 2_0528 (positions 90.54 to 118.78 cM) in 2H bins 07 to 08 of the Bowman backcross-derived line BW299 (4); eog1.c is associated with SNP markers 1_0996 to 2_0699 (positions 89.0 to 126.33 cM) in 2H bins 07 to 09 of the Bowman backcross-derived line BW300 (4); eog1.d is associated with SNP markers 1_0498 to 1_1402 (positions 81.43 to 119.86 cM) in 2H bins 07 to 08 of the Bowman backcross-derived line BW301 (4); eog1.e is associated with SNP markers 1_1493 to 2_0476 (positions 76.05 to 96.47 cM) in 2H bins 06 to 07 of the Bowman backcross-derived line BW302 (4), likely in 2H bin 07.

Description:

A multiple allelic series exists at this locus, which controls increased size of the outer glumes (glumes) of the spikelet. Glume width varies from 2.5 to 4.0 mm depending on genetic background and specific allele (17, 18). Glume awn length varies from awnless to nearly as long as the lemma awn (92 mm) depending on the eog1 allele present and genes at other loci (10, 17), but some confusion has occurred regarding alleles at the eog1 locus and expression of other glume characteristics (16, 17). The size of the glume can range from less than twice normal width in CIho 14955 to lemma-like glumes in Triple Bearded Mariout (5). Kernels of the Bowman backcross-derived lines for eog1.a (BW299) and eog1.c (BW300) were slightly larger than those of Bowman in non-heat stressed environments. Other morphological and agronomic traits of BW299 and BW300 were similar to those of Bowman (5).

Origin of mutant:

A spontaneous mutant and natural occurrence in a few cultivars (1, 17).
