BGS 155, Glossy leaf 1, glf1

BGN  47:81
Stock number: BGS 155
Locus name: Glossy leaf 1
Locus symbol: glf1

Previous nomenclature and gene symbolization:

Waxless bloom on leaves = w1 (16).
Glossy = gl (14).
Glossy leaves = gl (21).
Glossy leaf = gl (20).
Glossy seedling 2 = gl2 (6, 14).
Eceriferum-zh = cer-zh (9).


Monofactorial recessive (14).
Located in chromosome 4HL (5, 14, 17, 19); glf1.a is about 1.5 cM distal from the lbi2 (long basal rachis internode 2) locus (2, 6, 7); glf1.a is about 1.2 cM proximal from the Mlg (Reg2, reaction to Erysiphe graminis 2) locus (2, 6); glf1.a is associated with SNP markers 2_0820 to 1_0606 (positions 89.78 to 95.92 cM) in 4HL of the Bowman backcross-derived line BW385 (1), glf1.a co-segregated with molecular markers AK361226 and AK362558 (8), in 4H bin 06.


Surface wax coating on the leaf blade appears absent from the seedling stage to near maturity, and leaves have a shiny appearance (wax code ++ ++ -) (9). Plants are semidwarf, relatively weak, and late in heading. The stock in the Bonus is highly sterile (9), but the Bowman backcross-derived line has nearly complete fertility (3). The lack of surface waxes reduces the ability of growing germ tube of certain fungi to find the stomata openings (15). Plants of Bowman backcross-derived line BW385 were 5 to 15% shorter than Bowman and headed about 2 days later. Kernel weights were about 20% lower, and grain yields were approximately 3/4 of normal (3). Seedling leaf waxes in the cer-zh.54 mutant showed a 76% decrease in total wax load due to marked decreases of all wax classes except the esters (8). The gene mutated in cer-zh.54 was identified an elongase component, β-ketoacyl-CoA synthase (CER-ZH/HvKCS1) (8).

Origin of mutant:

A radiation induced mutant in Himalaya (CIho 1312) (14, 18), an X-ray induced mutant in Bonus (NGB 14657, PI 189763) (9).

Mutational events:

glf1.a (GSHO 98), glf1.b (gl2, GSHO 22) in Himalaya (CIho 1312) (18); glf1.f in 34-119-1, glf1.g in II-34-199-7-2 (GSHO 89) (4); cer-zh.54 (NGB 110938, GSHO 455) in Bonus (NGB 14657, PI 189763) (9, 10); cer-zh.266 (NGB 111153), -zh.308 (NGB 111195), -zh.357 (NGB 111244, NGB 117254), -zh.366 (NGB 111253), -zh.432 (NGB 111320), -zh.433 (NGB 111321) in Foma (NGB 14659, CIho 11333) (10, 13); cer-zh.325 (NGB 111212) in Foma (10); cer-zh.373 (NGB 111260) in Foma (11); cer-zh.865 (NGB 111753) in Bonus (12); glf1.h (MXM137) in Morex (CIho 15773) based on phenotype and SNP markers retained in the Bowman backcross-derived line BW384 (1, 3).

Mutant used for description and seed stocks:

glf1.a (GSHO 98) in Himalaya; cer-zh.54 ( NGB 110938, GSHO 455) in Bonus was used for allelism tests; glf1.a via R.I. Wolfe’s chromosome 4 multiple recessive marker stock in Bowman (PI 483237)*8 (BW385, NGB 20623, GSHO 2015); cer-zh.54 in Bowman*3 (BW164, NGB 21996); glf1.h in Bowman*5 (BW384, NGB 22146).
