In this work, Potato virus Y (PVY) resistant potatoes were generated using an environmentally safe construct. For this purpose, a ‘shooter’ mutant Agrobacterium-based transformation system was used. The isopentenyl transferase gene (ipt) present on the Ti plasmid of ‘shooter’ strains enhances shoot regeneration and can be used as a phenotypic selection marker. The introduced marker-free binary vector...
The freezing tolerance of 38 independent transgenic potato lines derived from the cultivar Desiree was tested in vitro using plantlets. The lines were transgenic for the DREB1A gene under control of the rd29A promoter, both of which were derived from Arabidopsis thaliana. The level of damage caused by freezing varied significantly among the transgenic clones and a non-transgenic control (cv. Desiree)...
