Figure 4. Transient expression of myosin XI-2 and XI-K tails changes the accumulation pattern of the MP.

Figure 4

A, co-expression of MP:GFP with RFP. The MP:GFP accumulates in PD. B and C, co-expression of the MP:GFP together with myosin XI-2 tails does not affect significantly the localization of the MP:GFP to PD (B) but causes the accumulation of the MP:GFP in a single big aggregate in the vicinity of the nucleus (C, arrow). D, transient co-expression of myosin XI-2 tails and MP:RFP in N. benthamiana transgenic plants expressing GFP:HDEL as ER marker (16c). Accumulation of the MP:RFP in a single aggregate near to the nucleus upon inactivation of myosin XI-2 correlates with the accumulation of the GFP:HDEL indicating that the MP aggregates are ER-derived. E, co-expression of the MP:GFP with myosin XI-F tails. The MP:GFP accumulates in PD similar as in the control with RFP (A). F and G, co-expression of the MP:GFP together with myosin XI-K tails has no significant effect on the localization of the MP:GFP to PD (F) but causes accumulation of the MP:GFP in several aggregates (G, arrow). H, immunoblot analysis using HA-specific (top panel) and GFP-specific (middle panel) antibodies for the detection of myosin and MP:GFP, respectively. Bands corresponding to the class XI (≈100 kDa) myosin tails are marked by asterisks. Coomassie blue staining (bottom panel) is shown as loading control. A-H, proteins were expressed by co-agroinfiltration and observed at 1 dpa. N, Nucleus. No, MP:GFP expressed alone. Scale bars, 20 µm (A-C and E-G) and 10 µm (D).
