Comment

A locus designated Gli-DT1 controlling an omega-gliadin of Ae. tauschii was mapped on the short arm of chromosome 1D between loci Gli-D1 (strictly Gli-Dt1) and Glu-D1 (strictly Glu-Dt1), 13.18 cM proximal to the former and 40.20 cM from the latter {02109}. The only omega-gliadin to date identified as being encoded by this locus, namely T1, is of unusually low electrophoretic mobility in SDS-PAGE gels and was formally thought to be a high molecular weight glutenin encoded by the Glu-Dt1 locus of Ae. tauschii (see note following the Glu-D1 list in section 'Glutenins'). The authors speculate that, due to their similar relative map positions, the loci Gli-A4, Gli-D4, Gli-R3, Gli-Sl4 and this locus, Gli-DT1, form a series of 'Gli-4' orthologous loci. However, this should be interpreted in the light of the above discussion on Gli-A3 and Gli-A4. A 1,200 bp Dra I RFLP was identified as a gene-specific probe for the T1 omega-gliadin {10645}.
