Abstract

The large subunit of Fraction 1 protein from Lycopersicon esculentum, Nicotiana tabacum and Petunia hybrida has been examined by isoelectric focusing of the S-carboxymethylated polypeptides, and by double immunodiffusion with antiserum raised against Fraction 1 protein. The immunological results reveal heterogeneity in the large subunit primary structure not identified by isoelectric focusing. A variable phylogeny can be generated depending on whether serological or electrofocusing criteria are used.
