BGS 29, Erectoides-d, ert-d
Stock number: BGS 29
Locus name: Erectoides-d
Locus symbol: ert-d
Previous nomenclature and gene symbolization:
Erectoides-7 = ert-7 (4).
Inheritance:
Monofactorial recessive (4, 5, 13).
Located in chromosome 7HS (1, 6, 13, 14); ert-d.7 is near the ert-a (erectoides-a) locus (11, 12); ert-d.7 is about 4.5 cM distal from the cer-f (eceriferum-f) locus (15, 16, 17); ert-d.7 is associated with SNP markers 1_0056 and 1_0576 (positions 51.93 to 54.30 cM) in 7H bin 04, with SNP markers 2_1338 and 1_0823 (positions 65.93 to 173.82 cM) in 2H bins 06 to 09 and with SNP markers 2_0193 and 1_1503 (positions 65.93 to 173.82 cM) in 3H bins 05 to 12 of the Bowman backcross-derived line BW306 (2). The ert-d locus is likely in 7H bin 04, but a 2HL/3HL translocation is required for full expression (2, 3).

Description:
Spikes have a compact or semicompact appearance caused by a reduction in rachis internode length, with rachis internode length values from 1.5 to 1.8 mm for mutants of group one and 2.1 to 2.7 mm for mutants in group two (14). Plants with an allele at the ert-d locus can be placed in two plant height groups, but mutants with compact spikes are not all in the short plant height group (14). The ert-d.7 allele is in group two based on rachis internode length and is closely linked to the translocation point (9). Rachis internode length increases following GA3 treatment of plants that have alleles at the ert-d locus (18).
