Název v původním jazyce

The speed of mitochondrial movement is regulated by the cytoskeleton and myosin in Picea wilsonii pollen tubes

Popis výsledku v původním jazyce

Individual mitochondria in pollen tubes show three classes of linear movement: high-speed movement (instantaneous velocities }5.0 ?m/s), low-speed movement (instantaneous velocities {5.0 ?m/s) and variable-speed movement (instantaneous velocities rangingfrom 0.16 to 10.35 ?m/s). Latrunculin B completely inhibited mitochondrial vectorial movement. Jasplakinolide treatment induced a 28% reduction in chondriome motility, and dramatically inhibition of high-speed and variable-speed movements. Treatment with 2,3-butanedione 2-monoxime caused a 61% reduction of chondriome motility, and the complete inhibition of high-speed and low-speed movements. Taxol increased the speed of mitochondrial movement. Oryzalin induced curved mitochondrial trajectories with similar velocities as in the control pollen tubes. These results suggest that mitochondrial movement at low speeds is driven by myosin, while high-speed and variable-speed movements are powered both by actin filament dynamics and myosin.
