Protein Electrophoretic Profiles and the Origin of the B Genome of Wheat

Abstract

Protein electrophoretic profiles cast doubt upon the prevalent theory that the B genome of the polyploid wheats was derived from a species of Aegilops. They suggest, instead

The extent and structure of genetic variation in species of the Sitopsis group of Aegilops

“…The extent of genetic variation found within the populations and species examined in this study is greater than previously reported in Sitopsis species (Johnson, 1972;Nakai, 1979;Brody & Mendlinger, 1980; The Genetical Society of Great Britain, Heredity, 74, 616-627. using seed from only a few plants. The amount of genetic variation found in the Sitopsis species was similar to that found in most other autogamous plant species but the extent of genetic diversity was higher (Nevo et a!., 1979;Hamrick, 1983).…”

Morocco as a possible domestication center for barley: biochemical and agromorphological evidence

“…The A-hordeins are less variable both in the cultivated and in the wild species than the B-, C-and D-hordeins (Dolí and Brown 1979;Shewry et al 1979Shewry et al , 1983 and are, therefore, more suitable biochemical markers in phylogenetical studies. Wheat CM-proteins were among those used by Johnson and coworkers in their exiensive studies on the origin and evolution of Aegilops-Triticum species (Johnson 1972: Johnson and Hall 1965. Our survey has been complemented with an agromorphological study of the H. spontaneum accessions.…”

Variability of 3 cytoplasmically encoded proteins in the Triticum genus

“…1956; Riley et a!., 1958), T searsii (Feldman and Kislev, 1977), T sharonense (Kushnir and Halloran, 1981), all from the Sitopsis section, or T. urartu (Johnson, 1972).…”
