“In Vitro” Analysis for Drought Tolerance of Different Transgenic Potato Lines Resistant to PVY

Abstract

Potato is an excellent staple food, but it is very sensitive to diseases, pests and different abiotic factors. Potato viruses are between the diseases causing great losses in potato crop production. In our previous research two different potato cultivars ('Baltica' and 'Désirée') were transformed using A. tumefaciens C58C1 pGV2260 with the hairpin construct pRGGYCPiPCY to obtain different potato varieties PVY^NTN resistant (Rakosy-Tican et al., 2010).

On the other hand, abiotic stress, such as drought, is another cause which determine the decrease of productivity in potato. One of the main methods for producing drought-tolerant plants is in vitro selection under water stress.
