    Notes: A potyvirus that induced stunting and a characteristic bushy appearance at the apical region, due to proliferation of terminal branches with narrowed, reduced and deformed leaflets, was isolated from chickpea in India. The virus was sap-transmissible to 14 species of Chenopodiaceae, Leguminosae, Solanaceae and Malvaceae; Chenopodium amaranticolor was a good local lesion host. Virus particles, trapped by immunosorbent electron microscopy and stained with uranyl acetate, were 710 ×10 nm long. Purified virus preparations contained a single polypeptide species of 32,500 Da and one nucleic acid species of 3.1 · 106 Da. The virus was serologically related to soybean mosaic, azuki bean mosaic and peanut mottle viruses but not to clover yellow vein, pea seed-borne mosaic and bean yellow mosaic viruses.On the basis of these properties, the virus was identified as a previously undescribed potyvirus in chickpea, for which the name chickpea bushy dwarf virus is proposed.

    Notes: A disease of peanut characterized by stunting of plants, veinal chlorosis, outward bending of leaflets, and proliferation of axillary buds has been observed in several parts of Peninsular India since 1977. The disease was restricted to peanut crops raised during the post-rainy season. A rhabdovirus was associated with this disease. This appears to be the first record of natural occurrence of a rhabdovirus in peanut.

    Notes: Summary.  The RNA-2 molecule of an isolate of the L serotype of Indian peanut clump virus (IPCV) was shown to consist of 4290 nucleotides with five open reading frames (ORF). The arrangement of the ORFs resembled that in RNA-2 of Peanut clump virus (PCV) from West Africa. The proteins encoded by the ORFs in IPCV-L RNA are between 32% and 93% identical to those encoded by PCV RNA. Partial sequence data for the RNA-2 of isolates of the H and T serotypes of IPCV show that the coat and P40 proteins encoded by the 5′-most ORFs of RNA-2 of IPCV-L, IPCV-H and IPCV-T are as similar to each other as any is to the corresponding proteins of PCV. A conserved motif ‘F-E-x6-W’ is present near the C-termini of the coat proteins of all three IPCV serotypes and of PCV, as it is in the coat proteins of other viruses that have rod-shaped particles, such as Tobacco mosaic virus and Tobacco rattle virus. The results support the distinction of IPCV and PCV as separate virus species, but also raise the question of how the serotypes of IPCV should be classified.

    Notes: Summary The complete nucleotide sequence of the S RNA of peanut bud necrosis virus (PBNV) has been determined. The RNA is 3 057 nucleotides in length, contains inverted repeats and two open reading frames (ORFs) with an ambisense coding strategy that are separated by an A+U-rich intergenic region. One ORF (1 320 nucleotides in the viral sense strand) encodes a Mr 49.5 kDa protein, identified as the nonstructural (NSs) protein based on similarity to published tospovirus sequences. The second ORF (831 nucleotides in virus complementary strand) encodes a Mr 30.6 kDa protein. This protein was identified as the nucleocapsid (N) protein based on sequence similarities. Amino acid sequence comparison of N and NSs proteins revealed identities of 22–34% with the reported tospovirus isolates of serogroups I, II, and III, whereas it had 82–86% identity with viruses in serogroup IV, watermelon silver mottle virus (WSMV) and tomato isolate of peanut bud necrosis virus (PBNV-To). Two subgenomic RNA species detected in PBNV infected tissue corresponded to the predicted sizes (1.65 and 1.4 kb) of the NSs and N mRNAs. The data presented show conclusively that PBNV should be included in serogroup IV, along with WSMV and PBNV-To.

    The nucleotide sequence of RNA-1 of Indian peanut clump furovius (1996)

    Notes: Summary The nucleotide sequence of RNA-1 of an isolate of the H serotype of Indian peanut clump virus (IPCV-H) was shown to comprise 5 841 nucleotides. The RNA contains three open reading frames (ORF) which are between nucleotides 133 and 3 522, nucleotides 3 526 and 5 103 (assuming expression by suppression of the ORF 1 termination codon) and nucleotides 5 168 and 5 539. The encoded polypeptides have M r , of 129 687 (p130), 60 188 (p60) and 14 281 (p14). ORF 2 is thought to be expressed by suppression of the termination codon of ORF 1 to produce a M r , 189 975 product (p190). p130 contains sequences characteristic of proteins with methyl transferase and NTP-binding properties and p190 contains these and sequences characteristic of RNA-dependent RNA polymerases. The nucleotide sequence of IPCV RNA-1 is similar to that of peanut clump virus (PCV) and corresponding encoded polypeptides are 88% (p130), 95% p60 and 75% (p14) identical. The sequences of the translation products are also similar to those of soil-borne wheat mosaic virus and barley stripe mosaic virus. Oligonucleotide primers, designed on the basis of the sequences of RNA-1 of IPCV and PCV, were effective in reverse transcription-PCR amplification of these RNAs and that of IPCV isolates of the serologically distinct L and T serotypes.

    Notes: Summary.  The nucleocapsids purified from peanut plants systemically infected with peanut bud necrosis virus (PBNV), a member of the genus Tospovirus, contained both viral(v) and viral complementary(vc) sense L RNAs. Defective forms of L RNA containing ‘core polymerase region’ were observed. The full length L RNA of PBNV was sequenced using overlapping cDNA clones. The 8911 nucleotide L RNA contains a single open reading frame (ORF) in the vc strand, and encodes a protein of 330 kDa. At the 5′ and 3′ termini of the v sense RNA there were 247 and 32 nt untranslated regions, respectively, containing an 18 nt complementary sequence with one mismatch. Comparisons of the predicted amino acid sequence of the L protein of PBNV with other members of Bunyaviridae suggest that the L protein of PBNV is a viral polymerase. The L protein had highest identity in the ‘core-polymerase domain’ with the corresponding regions of other tospoviruses, tomato spotted wilt virus and impatiens necrotic spot virus.

    The coat protein of Indian peanut clump virus: relationships with other furoviruses and with barley stripe mosaic virus (1994)

    Notes: Summary The 5′-most open reading frame of the c.4kb RNA-2 of Indian peanut clump furovirus (IPCV) encodes a protein of 208 amino acids. This protein is thought to be the coat protein of IPCV because its amino acid composition and Mr closely resemble those reported for IPCV coat protein and because its amino acid sequence is 61% identical to that of the coat protein of peanut clump virus (PCV) from West Africa. The extent of the sequence identity between IPCV and PCV coat proteins confirms previous conclusions that the viruses are distinct rather than strains of one virus. The sequences of the coat proteins of IPCV and PCV were between 18% and 26% identical to those of other furoviruses and those of unrelated tobamoviruses and tobraviruses. In contrast, the coat protein sequences were 37% (IPCV) and 36% (PCV) identical to that of the coat protein of barley stripe mosaic hordeivirus (BSMV). This similarity between the coat proteins of viruses from different groups (=genera) is unusual but is consistent with previous reports of sequence relatedness in various genes between certain furoviruses and BSMV.

    Evidence that whitefly-transmitted cowpea mild mottle virus belongs to the genus Carlavirus (1998)

    Notes: Summary.  Two strains of whitefly-transmitted cowpea mild mottle virus (CPMMV) causing severe (CPMMV-S) and mild (CPMMV-M) disease symptoms in peanuts were collected from two distinct agro-ecological zones in India. The host-range of these strains was restricted to Leguminosae and Chenopodiaceae, and each could be distinguished on the basis of symptoms incited in different hosts. The 3′-terminal 2500 nucleotide sequence of the genomic RNA of both the strains was 70% identical and contains five open reading frames (ORFs). The first three (P25, P12 and P7) overlap to form a triple gene block of proteins, P32 encodes the coat protein, followed by P12 protein located at the 3′ end of the genome. Genome organization and pair-wise comparisons of amino acid sequences of proteins encoded by these ORFs with corresponding proteins of known carlaviruses and potexviruses suggest that CPMMV-S and CPMMV-M are closely related to viruses in the genus Carlavirus. Based on the data, it is concluded that CPMMV is a distinct species in the genus Carlavirus.
