摘要：
The nucleotide and amino acid sequences of the movement protein (NSm) genes of five isolates of Groundnut bud necrosis virus (GBNV) originating from different hosts and parts of India such as cowpea and tomato from Kerala, groundnut from Tamil Nadu, and potato from Madhya Pradesh and Rajasthan were determined and compared to the known NSm sequences. Sequence analysis revealed that the NSm genes of GBNV isolates were identical in length (924 bp encoding 307 amino acids). GBNV isolates shared maximum identity (98-100%) at amino acid levels with GBNV-Type isolate, while 82-83% and 34-65% amino acid sequence identities were observed with Watermelon silver mottle virus and other Tospoviruses respectively. The NSm genes among GBNV isolates originating from different hosts and locations appeared highly conserved (93-100%), suggesting their common origin.
