Abstract: | Albumin and globulin fractions were extracted from dormant seeds of all 20 taxa of Lasthenia. After disc-electrophoresis on basic 7% acrylamide gels, mean Rp values, coefficients of variation and 95% confidence intervals were computed for both types of protein bands. Dendrograms were produced using similarity coefficients, indicating interspecific affinities among the taxa which differ from the sectional taxonomy of the genus. Protein data concerning certain problematical relationships are compared with published taxonomical and chemical data. |
