Figure 6. The tombusvirus p33 replication protein co-localizes with AtOrp3A and AtPVA12 proteins in Nicotiana benthamiana.

Figure 6

(A) Partial co-localization of TBSV BFP-tagged p33 replication protein with the YFP-AtPVA12 VAP protein in N. benthamiana cells. Expression of the above proteins from the 35S promoter was done after agro-infiltration into N. benthamiana leaves. Note the altered membrane structure in the subcellular area showing co-localization of BFP-p33 and YFP-AtPVA12 (portion of the image was enlarged at the bottom panel), which might be due to local membrane proliferation. (B) Co-localization of TBSV BFP-tagged p33 replication protein with the nYFP-AtPVA12 VAP and AtOrp3A-cYFP protein complexes in N. benthamiana cells. Expression of the above proteins from the 35S promoter was done after agro-infiltration into N. benthamiana leaves. Note that nYFP-AtPVA12 VAP and AtOrp3A-cYFP proteins were detected by BiFC. The subcellular areas (likely representing the ER membranes) where one viral and two cellular proteins are co-localized are marked with arrows. Control BiFC experiments were as in a previous paper (not shown) [56].
