摘要：

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