KASIB spring common wheat genotype identification on glutenin and gliadin subunits

چکیده
Based on the electrophoretic spectrum, analysis, 216 genotypes of spring wheat were identified as belonging to 25 types including 18 types of HMW-glutenin for 188 homogeneous cultivars. Most of the spring wheat KASIB could be characterized by the subunits 2 * 7+9 5+10 (40% genotypes), and subunits 2* 7+9 2+12– (30%) and subunits 1*7+9 5+10– (8%). The diversity appears to be determined by varying chromosome 1A and 1B at the 5 subunits and 1D-4 subunits HMG. Judging from the distribution of genotypes KASIB nurseries are mostly HMW-glutenin determining high quality baking by subunits: 1A-2 *(77-79%) and 1 (14-15%), at 1B-7+9 (81-82%) and 7+8(13-15%), by 1D –5+10 to 60%. A new subunit is to be included to this set ie., “4+10” for 1D for samples from Erythrospermum 55/9401-20 (Pavlodar Research Institute, KASIB8-9), Fiton 41 (KASIB 8-9) relative to genofund of high-quality genotypes found in Kazakhstan. Cultivar “Iridost” is identified with alleles 5.5+10 on chromosome 1D, previously identified for cultivars Tselinogradka, Tselinnaya 24, Akmola 3. In cultivar Chelyaba, chromosome 1B set possessed only 6+8 subunit and in the mix for cultivars Lutescens 29-94; for genotypes: E-607 and E-757 a rare characteristic subunit7*+8 was found. Genotypes OK -1, Fiton 25 and GVK 1916-9 carrying wheat-rye 1B/1R-translocation clustered distantly from all other genotypes. Wheat-rye translocation (IB/ IR) were identified more in samples for Omsk breeding and West Kazakhstan in each KASIB (exceptKASIB4-5), for all samples submitted “Kurgansemena” (except Lutescens415/00) and “Agrosemkonsalt” (KASIB8-9 and 10-11), as well as for LLP “Fiton” breeding samples (Fiton 41 and Fiton 43, including CIMMYT shuttle breeding material.

Characterization of Proteins from Grain of Different Bread and Durum Wheat Genotypes
The classical Osborne wheat protein fractions (albumins, globulins, gliadins, and glutenins), as well as several proteins from each of the four subunits of gliadin using SDS-PAGE analyses, were determined in the grain of five bread (T. aestivum L.) and five durum wheat (T. durum Desf.) genotypes. In addition, content of tryptophan and wet gluten were analyzed. Gliadins and glutenins comprise fr...

Six commercial U.K. cultivars of winter wheat selected to represent different abilities to partition nitrogen into grain protein were grown in replicated field trials at five different sites over three seasons. The proportion of LMW glutenin subunits decreased and the proportion of gliadins increased during grain development and in response to N application. Differences were observed between th...

The polypeptide subunits of wheat glutenin obtained after reductive cleavage of disulfide bonds have been separated into two fractions by a modified Osborne technique. Approximately 62% of the subunits by weight are soluble, as is gliadin, in neutral 70% ethanol; the ethanol-soluble subunits are mainly of 44,000 molecular weight (MW). The ethanol-insoluble glutenin subunit fraction is markedly ...

[b]Abstract Introduction and objective[/b]. Gluten proteins (gliadins and glutenins) are polymorphic wheat storage proteins of allergenic properties. Significant differences in chemical composition between both protein groups allow to expect highly specific immunological response of individual subunits and fractions in reactions with IgE sera of people allergic to wheat. The aim of these studie...
