| Abstract: | Seed storage proteins have proved to be a powerful biochemical marker for taxonomic research, but they have not been extensively employed in forest tree studies. In order to improve the understanding of the taxonomy of the genusPinus, total seed proteins of 12 pine species have been analyzed by means of SDS-PAGE (Sodium dodecylsulphate-polyacrylamide gel electrophoresis). The results showed the presence, in the genusPinus, of two main sub-taxa, corresponding to the subgeneraHaploxylon andDiploxylon. Differences and affinities between Mediterranean pine species were found in agreement with classification ofKlaus (1989). |
