2 Figure S1 Transient co-expression of U1:GFP and RFP-tagged marker proteins for the inner nuclear membrane or nucleolus/Cajal bodies in N. benthamiana epidermis cells. a-e) U1:GFP co-expressed with AtFib2:RFP, a nucleolus and Cajal body marker; f-j) U1:GFP co-expressed with AtSun1:RFP, a marker for inner nuclear membrane. a,f) GFP channel; b,g) RFP channel; c,h) autofluorescence of chloroplasts shown in blue; d,i) DIC channel and e, j) merged channels. Note that the nucleus shown in f-j represents the same nucleus as in in Fig. 1f. Bar represents 10 µm.

4 Figure S2 Transient co-expression of U2:GFP and RFP-tagged ER marker or endosome protein in N. benthamiana epidermis cells. a), d), g) and j) show U2:GFP, whereas b) and e) show the RFP fluorescence of the ER marker protein; h) and k) the RFP-tagged endosome marker protein. c), f), i) and l) merged pictures. Co-localization of U2:GFP and marker proteins appear yellow-orange. All pictures are projections of a z-stack, except pictures a-c) and g-i). Bar represents either 20 µm (a-c, g-i) or 10 µm (d-f, j-l).

Note that picture in g-i) represent a magnification of squared area in d) to show the web-like structure of the ER. Co-localization of U4:GFP and ER marker protein appear yellow-orange. All pictures are projections of a z-stack, except pictures g-i). Bar represents 10 µm (a-f) or 20 µm (g-i).

Nanoviral protein:cMyc:YFPN and nanoviral protein:HA:YFPC were expressed transiently in leaves of N. benthamiana plants and analyzed at 2 dpai by western blot analysis using either (a) anti-HA- or (b) anti-cMyc-specific antibodies for detection. Predicted molecular mass of nanovirus proteins and as BiFC constructs are summarized in panel c. Please note that U2-VenusC-HA is larger, and CP-VenusN-myc smaller than expected, which can only be explained by degradation and/or post-translational modifications. Expression constructs of U2-VenusC and CP-VenusN were sequenced several times and expressed several times with no different result as shown here.

7 Figure S5 Figure S5 Yeast-2-hybrid assay to confirm NSP & NSP interaction (GBT9 N + GAD N). Interaction of pSV40 + p53 serves as a positive control in this assay.

Note the re-localization of M-Rep in complex with CP to the nucleolus rim and speckles within the nucleus. White arrows pinpoint to the nucleolus (Nu) whereas (N) is the nucleus. Chloroplasts (Chp) are shown in blue. Bars represent 10µm.
