BGS 536, Eceriferum-yy, Cer-yy
Stock number: BGS 536
Locus name: Eceriferum-yy
Locus symbol: Cer-yy
Previous nomenclature and gene symbolization:
Glaucous head = ge (11).
Glossy spike 1 = Gle1 (10).
Glossy spike 1 = Gle1 (10).
Inheritance:
Monofactorial dominant (6, 9).
Located in chromosome 1HS (10); Gle1.a is about 4.2 cM distal from the Hor2 (Hordein 2, HorB) locus (3,10); Cer-yy.849 is associated with SNP markers 1_0654 to 1_0419 (positions 0.00 to 6.37 cM) in 1H bins 01 to 02 of the Bowman backcross-derived line BW154 (1); Gle1.a is associated with SNP markers 1_0654 to 2_1226 (positions 0.0 to 13.50 cM) in 1H bins 01 to 02 of the Bowman backcross-derived line BW383 (1), likely in 1H bin 01.

Description:
Surface wax coating on the spike appears absent (wax code - ++ ++) (7). Concerning the chemical epicuticular wax composition, the Cer-yy mutant in Bonus determines waxes lacking β-hydroxy-β-diketones and having relatively increased proportions of primary alcohols. The distribution of the lipid classes is similar to that of wild type plants (9). Other morphological changes were not observed in Bowman backcross-derived lines BW154 and BW383 with Cer-yy.849 and Gle1.a, respectively (2). Based on identical patterns of SNP markers retained in BW154 and BW383, Cer-yy.849 and Gle1.a originated from the same source (1, 2).
