Abstract
The polypeptide composition of Fraction I protein (ribulose-1,5-bisphosphate carboxylase) prepared from leaves of two clones of the parasexual hybrid plant Arabidopsis thaliana + Brassica campestris as well as their parents was analyzed by isoelectric focusing. The protein in hybrid plants contained a heterogenous population of small subunits resulting from the expression of both Arbabidopsis and Brassica nuclear genes, whereas the large subunit polypeptides, and hence the functional chloroplast DNA, were from the Brassica parent.Keywords
