Nucleotide sequence and genome organization of peanut stripe potyvirus

Virus-encoded proteinases of the picornavirus super-group.

“…The equivalent region of the proteinase domain of the polyprotein encoded by bymovirus RNA-2 does not, however, appear to contain this motif. This could correlate with HC-Pro : RNA binding in cis during the replication of HBE Review : picornavirus proteinases Review : picornavirus proteinases ;Ghabrial, et al, 1990) ; barley yellow mosaic virus (BYMV ; Kashiwazaki et al, 1989) ; Johnson grass mosaic virus (JGMV ; Gough & Shukla, 1993) ; pea seed-borne mosaic virus (PSBMV ; Johansen et al, 1991) ; peanut stripe virus (PSV ; Gunasinghe et al, 1994) ; pepper mottle virus (PMV ; Vance et al, 1992) ; plum pox virus strain D [PPV(D) ; Teycheney et al, 1989] ; aphid non-transmissible plum pox virus [PPV(NAT) ; Maiss et al, 1989] ; plum pox potyvirus isolate SK68 [PPV(SK68) ; Palkovics et al, 1993] ; Potato virus A [PV(A) ; Puurand et al, 1994] ; potato virus Y [PV(Y) ; Robaglia et al, 1989] ; shallot potyvirus (SPV ; S.

Frequent occurrence of recombinant potyvirus isolates

“…The locations of the putative recombination breakpoints are indicated by dashes below the alignments. The numbering is that of PStV-BI2 (Gunashinge et al, 1994), the last digit of each figure indicating the corresponding position. R denotes G/A when these nudeotides were equally represented at a given position in a sub-group.…”

“…As in the PVY analysis, three regions were selected and analysed. With nucleotide numbering according to the complete sequence of isolate PStV-BI2 (Gunashinge et al, 1994), the region N-ter extends from positions 8945-9118, C-ter from 9548-9808 and 3'NTR from 9809-10061. Fig.…”

Coat protein gene of a PStV-Bm isolate from West Nusa Tenggara, Indonesia

“…PStV is classified into the Potyvirus genus (Potyviridae). It is a single-stranded RNA virus that encodes several proteins, such as protein P1, helper component-proteinase (HC-Pro), protein P3, protein 6K (6K1), cytoplasmic inclusion (CI), 6K2, nuclear inclusion a (Nia), nuclear inclusion b and RNA-dependent RNA polymerase (NIb-Pol), and coat protein (CP; Gunasinghe et al 1994;Higgins et al 1998;Kim et al 2003;Elmahdi and El Salam 2016).…”
