We have monitored the response of potato to the infection with PVY NTN in two potato cultivars, a sensitive and a resistant one, 30 min and 12 hours after inoculation. Genes differentially expressed in both cultivars after inoculation, were those related to the photosynthesis, while genes involved in recognition and signalling were differentially expressed only in the sensitive cultivar. In the resistant cultivar we observed a strong differential expression of genes involved in defence response.

The whole RNA genomes of six European Potato virus Y (PVY) isolates, representing isolates of the PVYO, PVYN and PVYNTN subgroups, were sequenced and the reactions of a range of tobacco and potato cultivars after the inoculation were determined. The results resulted on the discovery of three new isolates of PVY. The occurrence of these biologically diverse isolates with their highly homologous genomes brings into question the exact nature of gene structure in relation to function.
