FIGURE 1

Schematic representation of the genomic organization of TYMV RNA and 206K protein processing. The open reading frames are indicated by open rectangles, and correspond to the 69K suppressor of RNA silencing and movement protein, the 206K replication polyprotein and the coat protein (CP). Protein functional domains of the encoded 206K protein are indicated. 206K is proteolytically processed at peptide bonds 1259–1260 (HEL↓POL) to generate 140K and 66K. The former is further processed at peptide bonds 879–880 (PRO↓HEL) to generate 98K and 42K (Jakubiec et al., 2007).
