โœฆ Synopsis

Two-dimensional electrophoresis revealed biochemical variation for glu-B1 high molecular weight (HMW) glutenin subunit 7 present in Dutch wheat (Triticum aestivum) varieties . This variation was not recognized by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) . In T turgidum ssp . dicoccoides, HMW glutenin subunits were detected which do not occur in varieties . Some of these subunits show similar relative mobilities during SDS-PAGE as subunits present in varieties and as such unambiguous identification is not possible . Before species related to T aestivum are used in a breeding programme, their HMW glutenin subunits should be identified by two-dimensional electrophoresis, in order to avoid the introduction of HMW glutenin subunits, of which the influence on bread-making quality is not known .

The diversity of high molecular weight (HMW) glutenin subunits of 502 varieties of durum wheat (Triticum durum) from 23 countries was studied using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Twenty-nine types of patterns were observed with 18 mobility bands. A total of 18

Restriction enzyme digests of DNA from nullisomic-tetrasomic and intervarietal chromosome substitution lines of wheat were probed with a high molecular weight (HMW) glutenin cDNA. Three restriction endonucleases were used to investigate restriction-fragment differences among five wheat varieties. Th
