Abstract: | The species specificity of heat shock proteins of callus cultures of Nicotiana chinensis, Nicotiana glauca, Nicotiana tabacum, Atropa belladonna, Lycopersicon peruvianum, as well as some somatic hybrids of A. belladonna + N. chinensis, was investigated by means of polyacrylamide gel electrophoresis in the presence of sodium dodecylsulfate. Despite the general similarity of electrophoretic mobility of heat shock proteins from different plants, a number of species-specific differences between the proteins of distantly related genera were found. Heat shock proteins may thus serve as genetic markers in somatic hybridization.Abbreviations hs heat shock - hsp heat shock proteins - SDS sodium dodecylsulfate - PAGel'phoresis polyacrylamide gel electrophoresis - TCA trichloroacetic aeid - NA-1(3;5;7;11;15) Atropa belladonna + Nicotiana chinensis, clone 1(3;5;7;11;15) |
