Studies on antigenic differences in needle proteins of Pinus sylvestris L., P. mugo Turra, P. uliginosa Neumann and P. nigra Arnold
By means of serological methods (double immunodiffusion, immunoabsortion and quantitative immunoprecipitation), using three kinds of antisera: antisylvestris, antimugo and antiuliginosa authors performed a comparison of antigenic properties of proteins from needles of <i>P. sylvestris, P. mugo, P. uliginosa</i> and <i>P. nigra</i>. Proteins characteristic for the species <i>P. sylvesiris</i>, and <i>P. uliginosa</i> were found. On the basis of the results obtained it was established, that the most distinct species are <i>P. mugo</i> and <i>P. sylvestris, P. uliginosa</i> is antigenically different from the two taxa but is showing greater similarity to <i>P. mugo</i> than to <i>P. sylvestris. P. nigra</i> proteins are different from proteins <i>P. sylvestris, P. mugo</i>, and <i>P. uliginosa</i>. They show however, some antigenic similarity to <i>P. sylvestris</i> proteins.
