Abstract

The nucleocapsid protein (N) gene of a Tospovirus causing potato stem necrosis disease was cloned and sequenced. The N gene of potato tospovirus isolates collected from potatoes from Gujarat, Madhya Pradesh and Rajasthan, India, were 831 bases long and could potentially code for a 276 amino acid-long protein. Sequence analyses showed that the N gene was most closely related to groundnut bud necrosis virus (GBNV). The amino acid sequence identity with GBNV was 98-99%, confirming that the potato stem necrosis disease is caused by a strain of GBNV, designated as GBNV-Po. Further, a high degree of sequence conservation among the N genes of GBNV-Po isolates (98-99% identity) was also observed
