Abstract
The electrophoretic characteristics of the cytoplasmically controlled large subunit of the Fraction I protein of 36 alloplasmic and three euplasmic control lines are reported. These lines, representing the cytoplasms of 32Triticum and Aegilops species, had either H- or L-type large subunits in their Fraction I protein; the diploid Triticum and most Aegilops species, including Ae. bicornisand Ae. sharonensis,had the L-type subunits; whereas, all the polyploid Triticum species (emmer, timopheevi, common wheats), Ae. speltoides, Ae. aucheri,and Ae. longissimahad H-type subunits. Therefore, section Sitopsis of Aegilops exhibits interspecific heterogeneity. The H-type is believed to have originated in the Sitopsis section from an L-type subunit because of the prevalence of the latter among the diploid species.This publication has 1 reference indexed in Scilit:
