Abstract

Glutenin subunits from nullisomic-tetrasomic and ditelocentric lines of the hexaploid wheat variety 'Chinese Spring' (CS) and from substitution lines of the durum wheat variety 'Langdon' were fractionated by reversed-phase high-performance liquid chromatography (RP-HPLC) at 70 °C using a gradient of acetonitrile in the presence of 0.1% trifluoroacetic acid. Nineteen subunits were detected in CS. The presence and amounts of four early-eluted subunits were found, through aneuploid analysis, to be controlled by the long arms of chromosomes 1D (1DL) (peaks 1-2) and 1B (1BL) (peaks 3-4). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that these four subunits are the high molecular weight subunits of glutenin, which elute in the order 1Dy, 1Dx, 1By, and 1Bx. Similar amounts of 1DL subunits were present (6.3 and 8.8% of total glutenin), but 1BL subunits differed more in abundance (5.4 and 9.5%, respectively). Results indicate that most late-eluting CS glutenin subunits were coded by structural genes on the short arms of homoeologous group 1 chromosomes: 6 by 1DS, 5 by 1AS, and 4 by 1BS. Glutenin of tetraploid 'Langdon' durum wheat separated into nine major subunits: 6 were coded by genes on 1B chromosomes, and 3 on 1A chromosomes. Gene locations for glutenin subunits in the tetraploid durum varieties 'Edmore' and 'Kharkovskaya-5' are also given. These results should make RP-HPLC a powerful tool for qualitative and quantitative genetic studies of wheat glutenin.
