An insight into differentially regulated genes in resistant and susceptible genotypes of potato in response to tomato leaf curl New Delhi virus-[potato] infection.

•Microarray analysis was done in contrasting potato genotypes inoculated with ToLCNDV-[potato].•Analysis indicated that 1111 and 2588 genes were altered (>2 fold) in K. Bahar and K. Pukhraj, respectively.•Cell cycle genes, R genes, HSPs, F-box proteins and transcription factors were identified in K. Bahar.•Several genes with unknown functions were 5 to 100 fold changed in both cultivars.•VIGS based studies were carried out for three DEGs in Kufri Pukhraj.
