Schematic representation of the organization of the five Pigeonpea sterility mosaic virus (PPSMV) genomic RNA segments (linear lines); their open reading frames (ORFs) (boxes), expression products of each genomic RNA (p1, p2, p3, p4 and p5) and their estimated molecular weights (kDa) are indicated. Letters A–F represent the conserved motifs on the RNA‐dependent RNA polymerase (RdRp) gene on RNA‐1; Gn and Gc indicate the N‐ and C‐termini of the glycoprotein on RNA‐2; N and C are the N‐terminal and C‐terminal ends of the proteins, respectively; nt, nucleotides.
