Research Abstract |
To understand how flagella and cilia respond to external stimuli and instantaneously modify their movement, regulatory mechanisms of flagellar and ciliary movement via calcium signaling during sperm chemotactic behavior and motility activation in Ciona intestinalis and ciliary reversal movement in sea urchin larvae were analyzed. Sensory mechanism of sperm chemoattractant, calcium-independent regulatory mechanism of flagellar asymmetry, cAMP signaling in sperm motility activation and calcium influx during ciliary reversal movement were revealed by these studies.
