Summary
Muscle actin filaments labeled with rhodamine-phalloidin were observed to move on the surface coated with a crude extract of pollen tubes ofLilium longiflorum with an average velocity of 1.99±0.55 μm/sec. The movement required both Mg2+ and ATP. These results indicate that the extract of pollen tubes contains a myosin-like translocator
