Watermelon bud necrosis virus (WBNV), a member of the genus Tospovirus, family Bunyaviridae is an important viral pathogen in watermelon cultivation in India. The complete genome sequence properties of WBNV are not available. In the present study, the complete M RNA sequence and the genome organisation of a WBNV isolate infecting watermelon in Delhi (WBNV-wDel) were determined. The M RNA was 4,794 nucleotides (nt) long and potentially coded for a movement protein (NSm) of 34.22 kDa (307 amino acids) on the viral sense strand and a Gn/Gc glycoprotein precursor of 127.15 kDa (1,121 amino acids) on the complementary strand. The two open reading frames were separated by an intergenic region of 402 nt. The 5' and 3' untranslated regions were 55 and 47 nt long, respectively, containing complementary termini typical of tospoviruses. WBNV-wDel was most closely related (79.1% identity) to Groundnut bud necrosis virus, an important tospovirus that occurs in several crops in India, and was different (63.3-75.2% identity) from the other cucurbit-infecting tospoviruses known to occur in Taiwan and Japan. Sequence analysis of NSm and Gn/Gc revealed phylogenetic incongruence between WBNV-wDel and another isolate originating from central India (WBNV-Wm-Som isolate). The Wm-Som isolate showed evolutionary divergence from the wDel isolate in the Gn/Gc protein (74.6% identity) potentially due to recombination with the other tospoviruses that are known to occur in India. This is the first report of a comparison of complete sequences of M RNA of WBNV.
