Molecular characterization of a Potato virus Y isolate from tomato crop in Yazd (Iran) based on sequencing of partial genome

Tomato (Lycopersicum esculentum Mill.) is one of the most important crops in Iran and throughout the world. In the previous survey conducted in 2013, PVY was introduced as the dominant virus in Yazd (Iran). In the present study, the partial genome sequence of a selected isolate called T5 was determined and analyzed. Following total RNA extraction of the T5 isolates, three fragments with 824, 1700 and 837 bp lengths were amplified using CPr/CPf, M4T/Sprimer and P1/P2 primer pairs respectively in RT-PCR. According to the nucleotide and amino acid sequences comparison of the CP, NIb and P1 regions of the isolate with the other PVY isolates in the Genebank, T5 is a member of NTN strain.
