Abstract
The method of biological ballistics (biolistic transformation, genetic bombardment) of plants is one of
the most modern methods used for direct gene transfer into plant cells. The main advantages of this method
include the ability to simultaneously incorporate several target genes into the plant genome, carry out transfer
without unnecessary agrobacterial parts and plasmid DNA sequences, and the short time needed to produce
transgenic cells. For different plant objects, the efficiency of obtaining transgenic plants by the ballistic method
varies from 1 to 3 %. For potato plants, the transformation efficiency is quite low at the moment and the selection
of optimal conditions for biolistics is one of the pressing issues of practical biotechnology. This article presents a
successful experience of introducing two genes of interest into two potato varieties using the biolistic approach.
The results of biolistic transformation experiments are presented for two types of explants: potato internodes
and calli of the varieties Aksor and Nevskiy. Of the 862 explants used for transformation, 56 regenerated plants
were obtained. PCR screening of transformants revealed one plant with the insertion of the chitinase gene, one
with the insertion of the endo-β-1,3-glucanase gene, and co-transformation by both genes was confirmed in four
regenerants. The average transformation efficiency for potato explants was 0.7 %. A high number of regenerants
(56) as opposed to a low number of transformants (6) reflects an attempt to increase the number of regenerants
by using a lower concentration of the selective agent (kanamycin). Although this approach requires more effort,
it can be used to produce potato lines with integrated genes of interest for further use in crop breeding. The lines
of potato obtained in the current study by introducing two genes associated with the plant response to fungal
pathogens will be further assessed for their resistance to fungal diseases and, if successful, will be used in potato
crop breeding.
