Experimental evolutionary studies on the genetic autonomy of the cytoplasmic genome "plasmon" in the Triticum (wheat)-Aegilops complex.

ABSTRACT: The term "plasmon" is used to indicate the whole cytoplasmic genetic system, whereas "genome" refers to the whole nuclear genetic system. Although maternal inheritance of the plasmon is well documented in angiosperms, its genetic autonomy from the coexisting nuclear genome still awaits critical examination. We tested this autonomy in two related studies: One was to determine the persistence of the genetic effect of the plasmon of Aegilops caudata (genome CC) on the phenotype of common wheat, Triticum aestivum strain "Tve" (genome AABBDD), during 63 y (one generation per year) of repeated backcrosses of Ae. caudata and its offspring with pollen of the same Tve wheat, and the second was to reconstruct an Ae. caudata strain from the genome of this strain and its pl
