Aim. The aim of our work was to obtain transgenic potato plants of Ukrainian varieties with the expression of a double-stranded RNA suppressor of proline dehydrogenase gene. We propose the decrease of proline degradation level and increase of overall proline concentration in obtained transgenic plants. Methods. The Agrobasterium tumefaciens-mediated method of genetic transformation to obtain transgenic plants of potato was used. Internodes of aseptic potato plants were transformed with a binary vector pBi2E containing an inverted repeats of two copies of proline dehydrogenase gene’s first exon and the gene of neomycin phosphotransferase II (nptII). Results. As a result of experiments kanamycin resistant transgenic potato lines of Deseiree, Belarusian 12 and Slavianka varieties were obtained. The transgenic nature of the obtained plants was confirmed by PCR with primers specific to the first exon of proline dehydrogenase and to nptII genes. Conclusions. The optimized conditions of genetic transformation and used agrobacterial strain allow to obtain the transgenic plants of a model potato variety Désirée, as well as varieties Belorussian 12 and Slovyanka which are of practical interest for cultivation in Ukraine. Keywords: transgenic plants, potatoes (Solanum tuberosum L.), stress resistance, proline.

The most serious insect pest problem in the potato crop in Colombia is the lepidopteran Tecia solanivora that causessignificant economic losses. In this research, we designedexpression cassettes based on the cry1Ba1 gene of Bacillusthuringiensis that could confer resistance to T. solanivora via the variety Pastusa Suprema. We selected the elements of thedesigned expression cassettes through an analysis of scientificliterature and patent databases; the considered factors were theproteolytic activation of the Cry1Ba1 protoxin, modification ofcodonic use, polyadenylation signals, and cryptic splicing sites. We used a tissue-specific patatine promoter to reduce potentialbiosafety risks, because it is expressed only in the tuber. Thefreedom to operate analysis suggests that the commercial use of the designed expression cassettes in transgenic potato plants does not affect the rights of third parties in Colombia.
