Аннотация
In this paper, the results of long-term screening of independently derived transgenic tobacco plants carrying the synthetic BWI-1a gene of serine proteases inhibitor from buckwheat are presented. For several years periodic spot checks of persistence and expression of the heterologous protective genes in vegetatively cloned collections and seeds of transgenic plants were conducted. The persistence of expression of the target gene after ten years of passage of plants in aseptic culture without selective pressure in their seed progeny for at least three generations and derived callus was shown. Extracts of tissues of all the variants of transgenic plants inhibited the growth of phytopathogenic bacteria and the germination of spores of fungi. The degree of the suppression of a pathogen in this case was hardly reduced. In the second seed generation, the number of defective seeds increased and there was a sharp decline of germination ability of the seeds even in nonselective conditions.
