Experimental Virus Evolution Reveals a Role of Plant Microtubule Dynamics and TORTIFOLIA1/SPIRAL2 in RNA Trafficking
Figure 2
Average absolute fitness (W) of the TMV ancestor and evolved lineages.
W is shown for infection in A. thaliana tor1/spr2, tor2 and WT plants, and in BY-2 protoplasts. Tor2 lineages show adaptation for efficient systemic movement in tor2 plants without consequences on replication efficiency (lack of a change in W compared to ancestor in protoplasts). Tor1 lineages are affected in replication efficiency and show slight adaptation for efficient systemic movement in tor1/spr2 plants. Asterisks indicate statistically significant differences from the ancestor.
